Cameron County Birdathon 2024

25 April 2024

            I didn’t hold high hopes of getting a big list today, as not only were the prevailing winds from the south (therefore pushing migrants right on through rather than forcing them to land on the coast), but they were pretty robust at 20-30 mph (with higher gusts)!  But as always, when the date is set, you do the best you can and just gladly embrace whatever God brings by!

            I usually start at Resaca de la Palma State Park an hour before dawn, as it’s a safe place to sit and listen for night birds!  The good news was that the main gate was open when I got there (normally I don’t think they open it until 7:00), but the bad news was that it was probably to allow the construction crew to get in early:  I had just discovered that morning while getting my on-line permit that they were resurfacing the tram road, so walking down to the “bridge” at the resaca was out!  But that also allowed me to sit near the Visitor’s Center where a Rose-throated Becard was reported, and where the Northern Beardless Tyrannulet usually hangs out (dipped on both, for the record), so I found a picnic table and enjoyed the dawn chorus (and scared a few Peccaries who wandered too close in the dark!).  I logged Pauraque (1) right as I pulled into the drive, actually, and White-winged Doves (2) were already going at it.  Sneezing Couch’s Kingbirds (3) were next, followed by several Brown-crested Flycatchers (4), all singing their unique “dawn songs”.  Eventually a McCall’s Screech Owl (5) trilled, and Mourning Doves (6) broke through the myriad Whitewings.  Cardinals (7) starting tuning up in the distance, and a White-tipped Dove (8) moaned from the woods.  A distant Altamira Oriole (9) did his happy whistle while a Mockingbird (10) drowned everything else out when he started up!  A few Green Jays (11) chattered from the woods, and a Great-tailed Grackle (12) made such a loud noise behind me that I thought part of the building had fallen off!  The sad song of a Clay-colored Thrush (13) wafted through, as did the rolling song of a Yellow-billed Cuckoo (14).  The Olive Sparrows (15) finally woke up with their bouncing-ball songs, and a Ladder-backed Woodpecker (16) laughed in the distance, followed immediately by a “chunging” Golden-fronted Woodpecker (17).  A Buff-bellied Hummingbird (18) rattled from the butterfly garden, and could barely pull out the guttural song of a Long-billed Thrasher (19).  Inca Doves (20) started singing “Bob Hope” from the parking lot, and when it was light enough to see, a Bronzed Cowbird (21) landed in a nearby tree and did his “Darth Vader” thing!

            About that time the crew had shown up, and somebody tripped the alarm in the Visitor’s Center, so since no one seemed in a hurry to shut it off, I figured it was time to move on (it was almost sunrise, the official “go-to-the-next-place” time anyway)!  Picked up a Black-bellied Whistling Duck (22) and yelling Kiskadee (23) on the way out, and the mesquite savannah along New Carmen Road added Red-winged Blackbird (24) and a singing Blue Grosbeak (25).  Heading north on New Carmen, a Peregrine Falcon (26) flew overhead, and heard Brown-headed Cowbird (27) and Eastern Meadowlark (28) on the fly.  A pair of Caracaras (29) were on a power pole, and a Common Nighthawk (30) “beented” unseen (I actually did have a nighthawk in the park, but he was silent, and it was too dark to see where the white band landed on the wing, so I was glad to hear this guy).  A House Sparrow (31) chirped at the buildings at the intersection with Olmito Road, and somewhere along here a Dickcissel (32) “bratted” overhead.  Heard both Western (33) and Tropical Kingbirds (34) from the car on the way to the freeway, and added Laughing Gulls (35) flying across the freeway!

            The next stop was the UTRGV campus in Brownsville, which can be good for parrots, but also had a couple of rare warblers recently.  Approaching the parking area for Lincoln Park, I heard Chachalacas (36) chorusing in the nearby woods, and Green Parakeets (37) screeching overhead.  A Baltimore Oriole (38) chattered from a small tree, and at the resaca a Common Yellowthroat (39) sang.  A Yellow Warbler (40) also sang and chirped from one of the trees, while a Carolina Wren (41) sang in the distance.  On the way to the bridge a Hooded Oriole (42) “wheeped” overhead, and House Finches (43) chirped in the trees.  The resaca was pretty empty, but a Snowy Egret (44) did fly right at me, and past the Pollinator Garden (where the MacGillivray’s Warbler had been seen), an Indigo Bunting (45) and Summer Tanager (46) sang from some trees near the shoreline (this was also the area where the lost Fan-tailed Warbler had been hanging out for three months).  I added the feral Muscovies (47) to my list, and on the way back a Tennessee Warbler (48) allowed a look.  Just before crossing the street some Black-crested Titmice (49) started calling and singing, and a Starling (50) fluttered around back in the parking lot.


Muscovy Duck

            Then it was time to head to South Padre Island, where most of the migration and shorebird action takes place!  On the way to the freeway added Rock Pigeon (51), and in the Bahia Grande wetlands along SR 48 added Great Egret (52), Roseate Spoonbill (53), and Great Blue Heron (54) on the fly.  Crossing the Queen Isabella Causeway added Brown Pelicans (55) diving for lunch, and a stop at the Stripes added Purple Martins (56) that were nesting in their light pole!

            Since the tide was out, I figured I could drive onto the Flats without rusting out my car (again), so was able to get close enough to the shorebird flock to actually see what was out there.  Willets (57) called incessantly, and Barn Swallows (58) were swooping all over.  Royal Terns (59) were on a sandbar, along with a lone Red-breasted Merganser (60).  Sandwich Terns (61) were with the Royals, and a white morph Reddish Egret (62) came sailing in and danced a little.  Although I could hear the Least Terns calling (63), I had to use the zoom on my camera to pick out a Black-bellied Plover (64) in the mix.  A Tricolored Heron (65) was providing fodder for a photographer that was on his belly shooting the birds, while Sanderlings (66) and Short-billed Dowitchers (67) fed further out.  Black Skimmers (68) were on another sand bar, along with a single Ruddy Turnstone (69), with a big flock of Dunlin (70) way out there that I again needed the zoom to identify!  A Neotropic Cormorant (71) batted by, along with a Ring-billed Gull (72).


Reddish Egret

Snowy Egret

            With the arrival of the south winds, the departure of the birders was evident, so I was able to easily find my favorite parking spot at the top of the “circular area” at the Convention Centre!  This area has several rows of foliage that provide great cover for migrating birds, and I had barely stepped out of the car before a Catbird (73) went zipping across!  Volunteers had put out seed where three days ago a Lazuli Bunting (a rare bird for these parts) had joined the Indigos, but this day only the Indigos were still there, joined by a female Rose-breasted Grosbeak (74) and a Dickcissel.  A Mottled Duck (75) quacked while I was shooting a female Painted Bunting (76 – never did see a male this day) and a female Tennessee Warbler that came in close.  Spent several minutes at the Drip where I added the ubiquitous Ruby-throated Hummingbirds (77), and a gentleman there had just photographed a Western Tanager (an expected migrant but rather rare)!  He (the tanager) never returned, so I headed out to the “back yard” where Peggy Rudman informed me that I “just missed” the tanager!   Unfortunately, when doing a Birdathon, you can’t spend too much time waiting for one bird, so I continued perusing the back yard, getting video of a female Summer Tanager and a Catbird having words over an orange!  A check of the Flats from the overlook added nothing new (the cormorants were lining the posts, as always), but a Savannah Sparrow (78) popped up from the grass, so that was worth it!  The Western had returned while I was gone , so I decided to sit at a nearby bench within calling distance for five minutes, adding an Orchard Oriole (79), Gray-cheeked Thrush (80), and Veery (81).  Then a lady I didn’t know called, “The Western Tanager is back!”  So I left everything on the bench (except my camera 😊) and ran over to bag him for the list (82)!  Spent five more minutes at the Drip where Black-necked Stilts (83) called from the wetland and a Hooded Warbler (84) came in for a bath.

            Headed next door to the Birding & Nature Center where some friends had reported some great warblers from the boardwalk there, so I had high hopes!  Added a Eurasian Collared Dove (85) calling in the parking lot, and in their little central pond Mom Mottled Duck had a little brood of ducklings!  What I assumed was a Mallard (86) in eclipse plumage was preening away, but Javi Gonzales (the center’s naturalist) bust my balloon when he told me it was actually a hybrid that’s been there for several years (a true Mallard would have molted out of eclipse several times over, which this one hadn’t…).  I was cheered by several Yellow-headed Blackbirds (87) over by their big waterfall, as well as a convention of Rose-breasted Grosbeaks at their tray feeder!  A Cattle Egret (88) was trying to hide in Songbird Alley as I went in to pay the entrance fee, after which I headed on the boardwalk where most folks were engrossed in the live alligator demo going on!  I squeezed by and rested at the first bird blind, adding Marbled Godwit (89) to the list amongst the shorebirds already logged.  Further down, their famous Mangrove Warbler (90 – currently just a race of the Yellow but a good candidate for a split as they’re so radically different in all respects) was singing away, but with the wind was content to stay hidden in the mangroves.  All the good migrants were being seen in a sheltered area “around the corner”, but alas, none of the wonderful birds my friends had seen that morning showed up except for a Warbling Vireo (91) and a Grasshopper Sparrow (92), which threw me at first, as I only see them in the open brushlands in winter!  In the open fresh water wetland a Common Gallinule (93) bobbed along while a Green Heron (94) called unseen.  A young White Ibis (95) was hanging with the whistling ducks, and added Blue-winged Teal (96) and a Coot (97) in the area where we had a Least Bittern three days before, along with a Tricolored Heron (who was still in the same spot)!  Added nothing new in the East Pond, but a brilliant Roseate Spoonbill posed as well as another Mottled Duck.  A non-Barn Swallow flew overhead that I concluded was a Northern Rough-winged (98), then spent a few minutes at the Parking Lot Drip; while not adding anything new, had nice encounters with Catbirds and a lady Summer Tanager.

            On to the Valley Land Fund Lots on Sheepshead, a famous migrant trap nestled in the midst of a residential area, where there was a little more action:  both Mr. and Mrs. Blackpoll Warbler (99) came in to an orange almost immediately after stepping out of the car!  I told Mary Volz to conjure me up something good for bird #100, and instead Father Tom pointed out a White-eyed Vireo on the ground, who eventually came right up to us!  (We all agreed that the Blackpoll would have been a better “#100”… 😊)  Lizzy Cavazos got me on a Black-and-white Warbler (101), after which they admitted that those wonderful warblers they saw on the boardwalk were seen early that morning (and it was already afternoon when I got there), which made sense – alas, you can’t be everywhere first thing in the morning!  There were plenty of already-logged Tennessee Warblers and Baltimore Orioles about, but I heard an Eastern Wood Pewee (102) while perusing the rest of the area, which was new.  While giving the north side 15 minutes in the shade of their bench, a Scissor-tailed Flycatcher (103) got added to the list while an Inca Dove vigorously courted a female next to me!

            The last ditch try for migrants was the Laguna Vista Nature Trail, so over we went, adding a Turkey Vulture (104) on the way.  This trail has three blinds with water features, and two of those blinds were already stuffed with birders, including Father Tom and Danny Salinas and his wife (Mary actually had to stand outside because there weren’t enough “holes” for her camera)!  The highlight here was a lovely Magnolia Warbler (105), but a female Orchard Oriole and Olive Sparrow also came in while I was there.  After ten minutes I headed for the next blind and “changed the guard” with Lizzy – nothing showed up here except another Ruby-throated Hummer.  Leaving that blind for the next one I was happy to hear a Curve-billed Thrasher (106) for the list, and a gentleman shooting something in the tree between us announced that he had a Verdin (107)!  The third blind was also stuffed with photographers, so I was the one to stand outside this time, only the sun was brutal and nothing was coming in, so I abandoned my post and headed for Palo Alto Battlefield.

            What I didn’t factor into the itinerary was the fact that they close the gates at 5:00!   The nice ranger let me rush out onto the trail long enough to add Cassin’s Sparrow (108 – dipped on the Botteri’s) and rush back before getting locked in!  From there headed to the Cannon Road Loop, which would be the last stop of the day.

            The loop actually consists of several eBird hotspots, but the actual Cannon Road hotspot is a tract of the Lower Rio Grande Valley NWR where the road passes through a lush area of Valley woodland.  Some Lark Sparrows (109) were cavorting along the road going in, but the target here was a Yellow-green Vireo (110) that had been setting up a territory for several years!  Thankfully was able to bag him right away and get a “proof” recording (they still get flagged as a review species), but he wouldn’t allow any video.  Tropical Kingbirds were all over, and down the road a bit a Lesser Goldfinch (111) was calling.  Leaving the woodland for some farmland and Adams Gardens Reservoir I added a calling Killdeer (112).


Tropical Kingbird

            I had seen a low-clearance car barreling down the dike along the reservoir and wondered, “How’d they get up there?!” when the area had been closed off for years!  But lo and behold, the southwestern access to the dike was open and graded, so up I went, and I was thrilled to see that indeed the southern dike was open and drivable!  Some local birders had reported lots of Hudsonian Godwits in the “southeast corner” of the reservoir (and at the time again thinking to myself, “How’d he get out there??”), and there were indeed lots of birds, so in short order I added Wilson’s Phalarope (113), Lesser Yellowlegs (114), Least Sandpipers (115), Shovelers (116), Long-billed Dowitchers (117), and Stilt Sandpipers (118) to the list.  Arriving at the famous southeast corner, I couldn’t find any Hudwits, but there was a nice flock of White Pelicans (119) along with more spoonbills!  It was getting late, and not having been back there literally in 15 years, I didn’t want to get myself in a spot where I couldn’t turn around, so I did so at a reasonably wide spot and headed back to the west end, adding a few fly-by Franklin’s Gulls (120).  I knew the western and northern dikes were open as Deb Anderson and I had driven them recently, so I checked the birds along that stretch; nothing new, but there were still lot of phalaropes, ducks, dowitchers, Black-necked Stilts, and a nice Marbled Godwit that was vocalizing.

            I wanted to check the sod farms for grasspipers before I lost the sun, so I blasted up to FM 800 and over to Weaver Road, then down to Hanka Sod, where Horned Larks (121) darted across the road on the southbound leg.  Didn’t have to wait long to hit pay dirt with several Buff-breasted Sandpipers (122) working the sod, but they were the only grasspipers to be had (but the best one, to be sure)!  I continued down Weaver and traversed that section of the NWR tract in hopes of adding Common Ground Dove and Groove-billed Ani; dipped on those targets, but got to see a nice Yellow-billed Cuckoo.


Buff-breasted Sandpiper

            Wrapped up the day with 122 species on my written list; eBird only recognized 119, as I unashamedly counted the feral Muscovies, the hybrid that I felt was really mostly Mallard 😊, and the “should be split” Mangrove Warbler!

Cameron County Birdathon 2023

4/30/23 

After being jolted awake at midnight by an Emergency Alert by the NWS warning of a severe thunderstorm on its way with 80 mph wind gusts, I didn’t get that planned extra two hours of sleep, especially when said storm hit with a vengeance!  Except for a couple of short glitches, thankfully the power didn’t go out (my boss and other friends around the Valley didn’t fare so well on that account L), and headed out to Resaca de la Palma State Park at 5:00 to hopefully bag some night birds and sit in the dawn. 

Had to park outside the park as the first gate was still closed (and the wind still howling to boot), but as I got settled, interestingly the first bird I heard was a migrant Dickcissel flying overhead in the dark!  Because the wind was so bad I opted to sit in the car and listen, and it was awhile before things started tuning up; the first brave soul was a White-winged Dove (2), followed by a distant Cardinal (3).  A Common Nighthawk (4) “beented” low overhead, and a Brown-crested Flycatcher (5) and Couch’s Kingbird (6) competed with their dawn songs.  I was very gratified to hear a distant Chuck-will’s-widow (7) singing from the woods, but was surprised that he beat out the resident Pauraques, which were soon to follow (8).  Soon more things joined the Dawn Chorus:  the sad lilting of the Clay-colored Thrush (9), the familiar cooing of the Mourning Dove (10), a rollicking Carolina Wren (11), a tittering Tropical Kingbird (12), a bouncy Olive Sparrow (13), and a raucous Green Jay (14).  As it got lighter a few Black Vultures (15) left their roost, and was very happy to log the distinctive “dear-dear-dear” of the Beardless Tyrannulet (16), a mid-Valley specialty making inroads into Cameron County!  Soon the Kiskadees (17) woke up, and a Great-tailed Grackle (18) flew over.  Some chattering from the trees betrayed the presence of several Baltimore Orioles (19 – these guys would be all over the county this day), and a Long-billed Thrasher (20) started his halting song. A Golden-fronted Woodpecker (21) called from somewhere, and a pair of Brown-headed Cowbirds (22) sat on the wire.  When the sunrise alarm went off and I prepared to leave, a singing Bronzed Cowbird (23) got in just under the wire!

Heading back up New Carmen Road to the freeway, a Turkey Vulture (24) sailed across the road, and several Eastern Meadowlarks (25) sang from the mesquite savannah on the west side of the road.  A Red-winged Blackbird (26) sang on a wire along Olmito Road, while a Black-crested Titmouse (27) whistled from a tree somewhere.  A couple of Starlings (28) flew across the freeway heading south, along with a few Rock Pigeons (29), and once off the freeway an onto the urban roads was able to hear House Sparrows (30) and log a Mockingbird (31) flying up to a snag.  I pulled over to write down what I had seen/heard before I forgot them (easy to do the older I get L), and in the process logged a calling Rose-breasted Grosbeak (32) in someone’s yard!

Turning right on Southmost Road, then turning right on Sabal Palm Road, added a singing Blue Grosbeak (33) in the field.  However, I was dismayed upon cresting the levee to discover that Sabal Palm Sanctuary was closed! L  I assumed it was due to storm damage (normally Wednesday is the only day they’re closed), but still disappointed in that this is one of the few places in Cameron County to bag the specialty woodland birds that favor the riparian forest (at least those you didn’t get at the dawn watch at Resaca de la Palma)!  So I turned around and at least stopped along the road for a couple of minutes to bag what I could, and added fly-by Barn Swallows (34), a flyover Laughing Gull (35), and singing Black-and-white Warblers (36).  An Olive Sparrow popped up for a picture, while a Harris’ Hawk (37) soared overhead and an Eastern Wood Pewee (38) caught bugs and returned to his snag.  A Chimney Swift (39) batted over, and about then another birder rolled by, saw the closed gate, turned around, and asked me about it – turned out he was doing a cross-country birding trip and was terribly disappointed that the place was closed!  But he was headed to South Padre Island next, and I knew the show would be good there (as the trees along the road were filled with more orioles)!  On the way out I bagged a Lark Sparrow (40) in the field.

Baltimore Orioles 

A pair of Black-bellied Whistling Ducks (41) flew over the road on the way to Old Port Isabel Road (herein OPIR), and about that time a report came over the LRGV Rare Bird What’s App group that the Sheepshead Lots on the Island were just hopping with migrants, including some hard-to-get warblers!  I was sorely tempted to drop the plan and run over there, but the Lord had to remind me that the point of a Birdathon is to hit the key habitats, come what may, and that it was best to stick with the plan.  So stick with the plan I did, and was rewarded at the first stop along OPIR (which can be a dicey dirt road but is necessary to bag certain coastal prairie species) with a singing Cassin’s Sparrow (42)!  Further down a Whimbrel (43) flew by, and the breeding Willets (44) were calling all over.  The only reason Cattle Egret was #45 was because I forgot to write it down once I got to OPIR (I had seen one in transit), but a Mottled Duck (46) and Snowy Egret (47) in the canal were technically the next birds seen.  Somewhere a Killdeer (48) called, and a pair of Caracaras (49) flopped around in the distance.  What was even more shocking was hearing the deep “double note” of a pair of King Rails (50) from a hidden wetland; normally an inland fresh-water bird, any reports in Cameron County get flagged, probably due to the similarity with the coastal Clapper Rail, and the reviewers want to make sure the person submitting the report really did have a King Rail!  In another little pond a Coot (51) and Northern Shoveler (52) got added, and finally logged a singing White-eyed Vireo (53) in the thornscrub.  Many swallows were going through:  mostly Barnies, but I was able to get on one long enough to nail down as a Bank Swallow (53).  A Verdin (55) chinked from the scrub, and at the pond past the “Creepy Chicken Coop” a Least Sandpiper (56) poked along.  A roadside bush had more Baltimore Orioles, but in addition, a Hooded Oriole (57) “wheeped” and then made a brief appearance! 

Not too far past that is where “county maintenance ends” where, unless absolutely dry, you don’t dare go any further (which is too bad, because the habitat down there can be good for Aplomado Falcon, which I dipped on), but a two minute stop at least added singing Bobwhites (58)!  I kept seeing these little birds zipping through and buzzing, and finally got a good enough look to safely count Indigo Bunting (59 – which I wasn’t really worried about as I knew there’d be droves of them on the Island), and a pale-rumped, dark-headed swallow proved to be a Cliff (60).  A cute Lark Sparrow posed for pictures by the road, and another little pond on the way out thankfully had a Least Grebe (61, as I usually get that one at Sabal Palm).  Past the railroad tracks in a flooded field a Lesser Yellowlegs (62) fed close to the road, and a whole flock of Franklin’s Gulls (63) lazed further out!  Huge Loma Alta Lake is always right in the sun, so I usually don’t give that much of a look, but this time it was easy to pick out a Roseate Spoonbill (64)!

So because OPIR was impassable (I really didn’t expect otherwise after the storm) I backtracked and headed up SR 48 to Port Isabel.  On the way I stopped at the boat ramp for shorebirds, as I figured The Flats behind the Convention Centre would probably be inaccessible as well, and it turned out to be very productive.  Along the highway picked up a Chihuahuan Raven (65) being chased by something (probably a Mockingbird), and at the boat ramp itself added squeaky Least Terns (66), Black Skimmers hunkered down in the vegetation (67), a Semipalmated Plover (68), and a single Neotropic Cormorant (69) in with the group.  A Royal Tern (70) flew over, and both a Sanderling (71) and Ruddy Turnstone (72) fed close to the parking lot.  A couple of Black-bellied Plovers (73) flew by, and heard the harsh calls of a Sandwich Tern (74).  Lastly, several Black-necked Stilts (75) were against the bank.

Headed up to the Island after that, adding a Brown Pelican (76) hanging in mid-air as I went over the causeway.  As expected, the parking lots closest to the Convention Centre were packed with the cars of birders looking to take advantage of the “fallout”, but I drove to the back of the building first to see if I could access The Flats via a little trail there (you can actually drive out there, but after being chastised by my mechanic for rusting out my car’s undercarriage, I try not to do that anymore), but the water was right up to the shore, so considering the probability that I wouldn’t be able to park any closer to the garden area, I just walked over from there.

During migration faithful volunteers will put out seed, oranges, and nectar for the tired birds, and the Ruby-throated Hummingbirds (77) sure appreciated that!  The wind was still howling, so it was tough to see migrants in the trees, but circling around the “back yard” managed to add Catbird (78), American Redstart (79), and Northern Waterthrush (80) to the list (Baltimore Orioles were still monopolizing the joint).  Ran into a couple of beginning birders who were puzzling over a bird they had seen, and were doubly alarmed as the only match in the book they could find was an Evening Grosbeak, which would be unheard of here!  I was puzzling myself, when I found a Dickcissel right where they said the bird had flown, so I got them on it, and that’s indeed what they had seen!

Heading out on the boardwalk a flock of Eastern Kingbirds (81) posed, and managed to add Great Blue Heron (82) and an immature Little Blue Heron (83) in the tidal area.  While others managed to get some good migrants in the mangroves, I couldn’t find a thing (not even the Pied-billed Grebes that are usually out in the bay), so I headed back and ran into Michael and Donna Marsden; Michael was a birding buddy who would often do some guiding for my boss Keith!  They had mentioned a Scarlet Tanager (which I had missed), but it showed again at the foot of the boardwalk so I could count it (84)!  A nice male Common Yellowthroat (85) popped up, while Michael had also reported seeing a Least Flycatcher and another puzzling Empid; thankfully the Puzzle came in, which turned out to be an Acadian Flycatcher (86)!  (Dipped on the Least, though… L).

I returned to the other boardwalk through the freshwater marsh and added Tricolored Heron (87), and at the blind at the end where I rested for five, logged a Common Gallinule (88), Green Heron (89), and a flyover Marbled Godwit (90)!  This particular boardwalk passes a pond where, on the way back, I spooked a pair of Blue-winged Teal (91), but also some shorebirds close by that I hadn’t noticed on the first pass, and wouldn’t have noticed this time if the Pectoral Sandpiper (92) hadn’t yelled at the Western Sandpiper (93)!  But in the mix was a larger sandpiper that I puzzled over, finally settling on Baird’s (94), because it can very similar to the White-rumped Sandpiper in some plumages.  I ran into Michael and Donna again at the foot of the boardwalk and told him about the sandpiper, and he was very anxious to go check it out (not Donna – she was there for the warblers J)!  He concurred that it was a Baird’s due to the all-dark bill (White-rumped has a chestnut base to the lower mandible which is diagnostic – if you can see it)!  He also picked out a Stilt Sandpiper (95) that I had missed, and an overhead swallow that turned out to be a Rough-winged (96).

Back at the gardens, warblers were showing up at the water feature and thereabouts:  was able to add Magnolia (97), Chestnut-sided (98), and an Ovenbird (99) almost at my feet that I couldn’t spot (my eyes are really getting bad L)!  Donna had seen a Golden-winged Warbler (one of those hard-to-find migrants) while Michael and I were grueling over shorebirds, and I so wanted that to be Bird #100!  So we waited patiently for it to show up (Donna spotted a Lincoln’s Sparrow, a common wintering bird, in the meantime and I refused to look at it J), but a Summer Tanager at the water feature ended up taking that honor!  A Veery (101) also popped up in there, and when I finally declared for the umpteenth time that I had to get moving (every new report of the Goldenwing sent me back J) I was able to add a Yellow Warbler (102) and a female Painted Bunting (103) on the way to the car.

Even though the next-door Birding and Nature Center boasts the same habitat at the Convention Centre (indeed, in the old days they shared boardwalks), good migrants can still show up there, so I swung in and spent five minutes at their “parking lot” water feature, where more Baltimores and Rose-breasted Grosbeaks showed up (in addition to another waterthrush), but nothing new for the list. While sitting at the Songbird Alley water feature a pair of Clapper Rails (104) sounded off from the salt marsh, and a young Orchard Oriole (105) came in to the drip.  I took a quick walk around their one-mile boardwalk loop and only added Short-billed Dowitcher in the shorebird department (106), and at the very end some flocking Purple Martins (107); the wind was just keeping everything down, including the vagrant Hammond’s Flycatcher I was hoping to bag!

Next was the Valley Land Fund Lots on Sheepshead, where I was hoping the action would still be as good as it had been that morning, but alas, a lot of the goodies had moved on (including yet another Goldenwing, and a Cerulean Warbler that was so tired it was giving everyone there great photo ops).  Again, faithful volunteers were putting out multiple oranges, and most of these were being claimed by Tennessee Warblers (108) in addition to the ubiquitous orioles.  I ran into Michael and Donna again, who pointed out a White-crowned Sparrow (109), a wintering bird I had to document as they should have left a while ago!  A Eurasian Collared Dove (110) made the list, as did an Inca Dove (111) that Donna found for me (I think she was amused by my getting excited about that, but for a Birdathon, every species counts)!  They had just seen the reported Lazuli Bunting, so we staked out that corner of the observation area to no avail, then watched the berm where dozens of Indigo Buntings and a few Dickcissels were feeding, hoping he might go there!  We got a Swainson’s Thrush (112) instead, and an Orange-crowned Warbler (113) came to a close orange.  Michael had told me about a Hooded Warbler back where I had parked, so I went back there, hoping to add it, but could only kick up a nonetheless very cooperative Redstart!  Another birder there said, “Did you find your Hooded Warbler?”  No.  “There it is right there!”  Great bird, with chuckles all around (114)!

After checking out the whole area and not finding anything new, decided to head across the causeway and over to the Laguna Vista Nature Trail, another good migrant trap.  After parking and entering the trail, hit pay dirt with a Black-throated Green Warbler (115) in the little grove of trees there (which can often be the birdiest spot in the place, despite the three blinds with water features)!  Heading to the first blind I ran into Michael and Donna again, who reported a Blackburnian Warbler back at the entrance, so I went running back to spend about five minutes looking.  No Blackburnian, so I shuffled back to Blind #1, where a gentleman had just finished putting out some food and had reported a Kentucky Warbler and Yellow-breasted Chat!  So I spent a little over five minutes there (I normally spend 15 but on a Birdathon you gotta keep moving) and was able to pick up a Buff-bellied Hummingbird (116) at the feeder!  Nothing came in to Blind #2, but on the way to #3 a Common Ground Dove (117) flew out of the thornscrub and landed briefly on the trail!  In the blind, the White-tipped Doves (118) were doing their coke-bottle coos, and one even flew overhead in a display flight!  Was happy to pick up a Ladder-backed Woodpecker (119) calling, and mused about how all my additions were not migrants, but local birds that I otherwise would have probably picked up at Sabal Palm had they been open! 

But things livened up back at that little grove:  migrants were in and out, with yet another waterthrush in a puddle and Magnolia Warbler in the trees, but was thrilled to log a Yellow-throated Vireo (120) that gave great looks!  A Nashville Warbler (121) peeked at me, and from another tree a lovely Northern Parula (122) made a pass!  But even more exciting for me was a Philadelphia Vireo (123), not much to look at but a challenge to ID sometimes, and even easy to miss some years!  Back at the car, I was chatting with Lizzie, another birding buddy, when I noticed a note on my car:  it was from Donna, saying that the Blackburnian had come back!  Well, I did spend another five minutes staring down the tree she had him in to no avail, so I sadly let that one go… 

Backlit Magnolia Warbler

There were reports that Port Isabel Reservoir had some good shorebirds, but when I got there the trail I normally go on was impassable, and another entrance down the [dicey] road yielded nothing new (besides being blown off your feet and looking right in the sun), so I wrote that one off and took the back roads to the freeway, picking up White-tailed Hawk (124) on the way.  The next destination was Hanka Sod Farms on Weaver Road, as some migrant shorebirds favor that habitat.  But I first made a quick stop at the Ebony Unit of Longoria WMA where the resaca there yielded a Spotted Sandpiper (125) and several lovely Wilson’s Phalaropes (126), in addition to previously-logged ducks and coots.  Back at the car a Lesser Goldfinch (127) “wheed”, and driving slowly through the NWR tract on the way to Weaver Road bagged a calling Great Crested Flycatcher (128).  Sadly, there were no shorebirds at all on the sod fields (except for Killdeers), but did have several Lark Sparrows feeding close to the road!  Said road past the admin building was too slick to drive on (lots more sod fields are down that road), so I backtracked and headed up to FM 800 where hopefully the La Feria Sod Farms (also owned by Hanka Sod, I noticed) would have something.  Thankfully they did, and thankfully they showed up at a spot where I could safely get off the road:  three American Golden Plovers (129), a shorebird that only comes through in spring, so I was very happy to bag them!

Last stop of the day was Tiocano Lake, another NWR tract on a narrow road heading to Santa Rosa.  There are very few spots to safely pull over (and despite the 30 mph speed limit, locals fly down that road like nobody’s business), but right away I was treated to a mob of feeding shorebirds, most of which were Wilson’s Phalaropes and Stilt Sandpipers!  Fulvous Whistling Ducks (130) were calling unseen (until a little later), and added Long-billed Dowitcher (131) and Semipalmated Sandpiper (132) to the day list.  Crawling down to the intersection added a Loggerhead Shrike (133) on a wire before turning around, and then headed down to the one place you can get totally off the road, near a little fresh water opening where I parked and waited for sunset.  This is always productive, as just sitting and listening added Sora (134) and yet another King Rail (this is actually the most reliable place in the Valley to get that bird)!  Some White-faced Ibis (135) flew past, and as I got on a flock of egrets, I noticed a couple of young White Ibis (136) in with them!  A Yellow-crowned Night Heron (137) called from the opposite shore, and to the east I could make out the sharp “kleeping” of some American Avocets (138) along with the barking of the stilts.  The last bird of the day was a surprise flock of Yellow-headed Blackbirds (139)! 

Shorebirds at Tiocano Lake

At least I thought that was the final total:  I submit checklists to eBird for each place I visit, and while I might forget to write something on the running list, I rarely forget to enter things in the checklists as the pre-determined checklist itself reminds me of what I saw/heard.  Well, it turns out that I forgot to write down four birds, all along OPIR:  some Gull-billed Terns (140) feeding in the field with the Franklin’s Gulls, a Scissor-tailed Flycatcher (141) on a wire, a Great Egret (142 – actually had several that day), and an Upland Sandpiper (143) that took off and called shortly after starting on the road!  Despite some serious misses, the Lord certainly blessed!
