Trip Report: South Texas, November 11-19, 1999

Urs Geiser, Woodridge, Illinois, USA;


The Lower Rio Grande Valley of Texas is one of the few "must see" destinations for any serious North American birder (the others being southeastern Arizona and south Florida); places of great bird abundance with a good sprinkling of across-the-border species that are not easily seen elsewhere. This was my first trip to that area, and it had a potential of almost 80 life birds (including a good number of unlikely rarities). 40-50 life birds were a more realistic goal. Furthermore, it gave me the opportunity to see again a number of coastal species that I hadn't seen since a trip to Florida as a beginning birder in 1989.

November is the time of the annual Rio Grande Birding Festival (in addition to the time of the year when many of the Mexican strays show up), and we decided to take advantage of at least one of their field trips to see some of the more difficult species. However, the festival is a large affair, and in the end, I was glad to stay away from it for the most part.

I originally planned on traveling with my friends, Bob and Karen Fisher, who had already visited the Valley once before, but human and feline health problems caused them to cancel on short notice. I decided therefore to do the trip alone. I was able to obtain a cheaper airfare to Corpus Christi than directly to the Valley, and thus it was decided to take advantage of the vicinity to Aransas N.W.R., winter home of the endagered Whooping Crane. (I actually managed to observe three crane species within six days, after seeing an extraordinary Common Crane in Indiana on 11/6/99.)

From Corpus Christi, travel was by rental car, and all lodging was in standard chain motels (pre-booked). The major highways leading out of the Valley have immigration checkpoints, thus proper identification papers (in my case, Resident Alien card) are required to avoid problems. Restaurants are plentiful in the larger towns, although only one chain of fast food serves breakfast before 6 a.m.

The weather was sunny every day (except for some passing threatening clouds on the 15th) and warmer than average for the season, with highs in the upper 80s (around 30°C) and lows in the upper 50s or lower 60s (around 15°C). On several days, there was early fog that disappeared during the morning. On most days, there was a light wind from the east. Sunrise was a little after 7am and sunset before 6pm.

For reference material, I had the brand-new 3rd edition of the National Geographic Society's Field Guide to the Birds of North America (1999), S.N.G. Howell and S. Webb's A Guide to the Birds of Mexico and Northern Central America (Oxford University Press, 1995), and a borrowed older edition of A Birder's Guide to the Rio Grande Valley (ABA Lane Guide Series). The registration material from the birding festival contained a Texas state highway map and the Rio Grande Valley Birding Map. The latter, which is apparently available for free (advertisment supported) from local sources, proved to be extremely useful. Not only were there many more roads shown than on the state map, it also contained a large list of birding places with descriptions on the back side. I would strongly suggest for any visitor to find this map at the earliest convenience. On the other hand, it is probably not necessary to bring a DeLorme road atlas, as most of the birding places are well signed and access described in the afore-mentioned sources.

I have posted a separate picture gallery with some of the better photos from the trip.

Itinerary - Daily Accounts

With a total of eight nights, it was decided to spend three nights in the lower Valley (Harlingen, the site of the festival), and three in the upper Valley (San Juan near McAllen). The first night had to be in Rockport for the boat trip to Aransas, and the last one in or near Corpus Christi, as it would be rushed to drive all the way from the Valley and catch a plane on time. Furthermore, the Corpus Christi area offers some nice coastal birding, which meant that the coastal locations of the Valley (Boca Chica N.W.R. and South Padre Island) were not necessary to visit.

Thursday, November 11 - Arrival

I arrived in Corpus Christi at 4 p.m. After noticing my first life bird (the abundant Great-tailed Grackle) and settling into the car, I wanted to find some birds during the last hour of daylight. I passed the downtown area and crossed over the huge bay bridge direction north. At the north end of the bridge there is a little park, Indian Point Park, where I pulled away from the highway. There were numerous shorebirds, pelicans, herons, gulls, terns, and I had a teaser look at possible Cave Swallows. After sunset, I drove to Rockport, where I spent the night.

Friday, November 12 - Aransas N.W.R., Fulton - Corpus Christi - Drive to Valley

In the morning fog, I arrived at Capt. Ted's dock in Fulton before 7 a.m. However, as there were only a handful of people present, we had to wait for a church group with reservations that was stuck in traffic in the fog and didn't arrive until 40 minutes later. Luckily, the fog lifted just about then. The boat crossed the bay fairly quickly and only slowed down when it entered the channel along the edge of Aransas N.W.R. There were again numerous wading birds including some Roseate Spoonbills, and soon, we saw our first Whooping Cranes, a family of two adults and a brown immature. While not close, they were easily seen with binoculars. We later saw a few more distant birds, not all within the refuge boundaries. Other interesting birds were the first Neotropic Cormorants, Common Loons, Am. Oystercatchers, White Ibis, Reddish Egret, and Clapper Rail. Back at the dock, I noticed that among the gulls and terns perched on harbor pilings there were three late Sandwich Terns, an unexpected bonus bird.

Capt. Ted handed us a sheet with suggested land birding spots in the area, and I decided to try out a few. A pond in the town of Lamar held a number of Black-bellied Whistling-Ducks, as well as a couple of large Alligators (the only ones seen on the trip). I drove the backroads of Fulton and eventually crossed the west arm of Copano Bay, attempting to reach U.S. 77 in Sinton. However, road construction forced a detour, and it became more direct to go through Corpus Christi again. I therefore decided to pay Indian Point Park another visit and found a few new species there, including Piping Plover and yet another Clapper Rail.

I spent most of the rest of the afternoon driving south on U.S. 77, spotting a Harris's Hawk without being able to stop the car to take a good look. I arrived in Harlingen around 5 p.m. and spent the last daylight along the road to Laguna Atoscosa, where I spotted the first White-tailed Kites of the trip. I love these elegant birds! I spent the next three nights in Harlingen.

Saturday, November 13 - Laguna Atascosa N.W.R. - Brownsville

Most of this first full day of birding in the Rio Grande Valley was spent at Laguna Atascosa N.W.R. I was duly awed by the gaudy Green Jays at the photo blind which also yielded a few more life birds: White-tipped Dove, Inca Dove, Bronzed Cowbird, and Olive Sparrow. The trails around the visitor center were relative unproductive, partially due to the season and partially due to the drought - none of the small wetlands along the trail contained any water. Nevertheless, I found a few new birds, including the two common woodpeckers and several Great Kiskadees.

The freshwater namesake Laguna Atascosa, on the other hand, was choke-full with herons, ducks, coots, pelicans, and shorebirds. Nothing extraordinary, but just lots of birds!

Later in the hot midday sun, I took the long auto tour. Most of the shallow wetlands were again dry, and the birds were found on the main lagoon (part of Laguna Madre): thousands of Redhead and Northern Pintail were most evident. I managed to pick up another Piping Plover at the beach. Inland again, a Merlin perched in a low tree was a nice find, but the Paisano Trail only yielded a Greater Roadrunner.

Back at the visitor center, I ran into the Pete Dunne hawk workshop whirlwind outing with their huge tour buses - not my taste of birding, irrespective of the guy's accomplishments and deserved reputation. I prefer a slower pace and absolutely hate crowds.

To round out the day, I decided to check out one of the places listed on the Birding Map for parrots, and I picked Dean Porter city park in Brownsville. I didn't find any parrots that evening, but the resaca (oxbow pond) held a Least Grebe, and ducks, including some Black-bellied Whistling-Ducks, were feeding in someone's back yard.

Sunday, November 14 - King Ranch - Harlingen - San Benito Area

Despite my distaste for large groups, I had signed up for the King Ranch field trip, mainly to see Ferruginous Pygmy-Owl, which would probably be hard to find on one's own. Another target species was Audubon's Oriole. The King Ranch takes up all of Kenedy County and then some. It contains a number of different habitats, and it is not really overgrazed, so that large tracts of fairly decent live oak woods survive in its holdings. We birded the southernmost section of the ranch, which is apparently the best for birding. A large tour bus nimbly negotiated the gravel roads and the numerous gates. The guides, all employees of the King Ranch, were very capable, although I thought that they overplayed the screech-owl tape way too much to lure in random passerines. For the owl of course, it is almost essential, and the orioles were also brought out into the open buy a recording of their song.

It didn't take the guides too long to find a Ferruginous Pygmy-Owl which was later joined by a second, and they set up scopes for everybody to have good looks. While following the Audubon's Orioles into the woods, we accidentally flushed a Pauraque from the forest floor, and at the same time someone found an Eastern Screech-Owl hiding in a tree trunk.

A ranch pond held a number of ducks (including the only Cinnamon Teal of the trip), herons and shorebirds. Other interesting birds were several Crested Caracaras, White-tailed Hawks, Pyrrhuloxia, Verdin, and Vermilion Flycatcher, but Tropical Parula was elusive. I finally got a good look at a "certified" Long-billed Thrasher, something I had struggled with the previous day at Laguna Atascosa.

After our return to Harlingen, I was ready for some more quiet birding. I first checked out Hugh Ramsey park in Harlingen. There weren't a lot of birds there, but I had a quick look at a Green Kingfisher, and a Curve-billed Thrasher was pointed out by other birders.

I then drove around the country roads south of Harlingen, especially the area around the Las Palomas Wildlife Management Area. Of interest there was a Couch's Kingbird that actually called a few times for positive identification. Several Least Grebes were in a resaca, and I saw another Curved-billed Thrasher and the only Cooper's Hawk of the trip.

There remained just enough time for another attempt at parrots. This time, I followed some other birders' advice and went to the town of San Benito, where Green Parakeets had been seen a few days earlier. Indeed, I did find the flock in a trailer subdivision behind the local Wal-Mart, and it also contained an Aztec (a.k.a. Olive-throated) Parakeet, a species that is not currently accepted as established in the A.B.A. area. However, a conversation with a local resident revealed that the Red-crowned Parrots that used to frequent the same neighborhood had apparently moved on to some unknown other location a few weeks earlier.

Monday, November 15 - Brownsville - Sabal Palms - Santa Ana N.W.R.

Not counting the coastal locations, the remaining "must do" spots in the lower Valley were the Brownsville landfill and Sabal Palms Audubon Sanctuary (the southernmost point in Texas), thus I drove to Brownsville in the morning twilight. A large kingfisher at a bridge of the bypass road could have been a Ringed, but it disappeared before I was able to stop the car for a better look. I had conflicting information whether Sabal Palms would be open on Mondays or not, but since this was my only chance during this trip, I tried it anyway. However, the gate was locked, and I went to the landfill instead.

The Brownsville dump is well equiped for visiting birders, with a reserved birders' road separate from the garbage truck traffic. Unfortunately, during my visit the dump operations were not directly visible from the birders' road, and the view at the swirling flock of birds (mostly gulls, but also grackles, vultures, and starlings) was distant. No corvids were in sight, however, and I spent well over two hours waiting and also looking at the other birds. A Peregrine Falcon made occasional passes over the dump, and among the more interesting fly-by birds were two Roseate Spoonbills. Eventually, crow-like birds started to fly in from the south, but they were all "only" Chihuahuan Ravens, not the more sought-after Tamaulipas Crow. At that time, a couple from Massachusetts (Ed and Amy Slattery) drove up and told me that Sabal Palms was open now.

We abandoned the dump and drove the couple of miles back to Sabal Palms, which was indeed open now. A naturalist told us where he had seen a Clay-colored Robin that morning, so we went looking for it right away, but without success. At least we had excellent looks at a pair of Altamira Orioles. The couple from Mass. then returned to the visitor center to watch the hummingbird feeder while I took another look at the pond, which held a variety of water birds, including a few more Least Grebes. Just when I returned to the visitor center, I was told that I just missed a Buff-bellied Hummingbird, but then the naturalist took the feeders down. Apparently, they were closing up (officially, they were closed on Mondays, anyway, but they had some work to do on that day), and they don't leave the feeders outside when nobody is around. At least there were a number of Chachalacas to look at. I waited around the flower garden a little longer, hoping that the hummingbird would show up there with the feeder gone, but no luck.

Now it was time to move up the valley, and after crossing Brownsville (where I almost ended up on the international bridge), I followed U.S. 281, the old Miltary Highway, to Santa Ana N.W.R. where I arrived mid-afternoon. The wildlife drive wasn't open that day (nor was it on the following Thursday), thus I had to explore on foot. I covered a combination of the A and B trails around Willow Lake, with a side trip to Pintail Lake. The major bird concentration was at Willow Lake with a lot of shorebirds and ducks, and finally a Ringed Kingfisher. A calling Sora was the best bird at Pintail Lake, but there I was able to sneak up very close to an Armadillo, which was a life mammal. Finally, I drove to San Juan, where I stayed for the next three nights.

Tuesday, November 16 - Bentsen-Rio Grande Valley St.P. - Anzalduas Co.P.

I arrived at Bentsen-Rio Grande Valley St.P. (in the following, just "Bentsen") around 7 am when the park officially opens. I waited around the entrance station to pay my $2, but nobody showed up for 15 minutes, at which time I gave up. During the wait, I spotted an immature/female plumaged hummingbird that was definitely not a Buff-belly, but probably a Ruby-throated Hummingbird, also two Yellow-bellied Sapsuckers, and assorted passerines. My next stop was the trailer loop, where many "winter Texans" operate bird feeders. A Clay-colored Robin had been seen the week before at No. 18, but the tenants, the Culbertsons (Jim is well known for his bird photography, having photographed over 600 ABA species including the famous Stygian Owl of 1996, and his wife Pat was also very knowledgeable - her detailed instructions were crucial for my finding the Rose-throated Becard two days later), thought that the large crowds of the birding festival had driven the bird away.

Later, I checked out the picnic and boat ramp area. A rare (for the area) Red-naped Sapsucker was known to frequent trees near the boat ramp, and I was able to find it easily. I then tried to find a purported, totally out of place Fan-tailed Warbler (Basileuterus lachrymosa), but later scrutiny of the evidence convinced me that the observer had just seen an immature Common Yellowthroat with a fuzzy dark face that was definitely present ("but it flicked its tail just like the book says!"). This was probably the same bird that other birders had declared to be a Black-polled Yellowthroat (Geothlypis speciosa, a sedentary endemic of central Mexican marshes and extremely unlikely vagrant). A place like Bentsen, where rarities show up with some regularity, really ignites the imagination of some birders!

A pair of Least Grebes and both specialty kingfishers were more real, and I was actually able to watch a Green Kingfisher perched for a change. A midday walk on the Rio Grande River trail was unproductive, except for an encounter with a group of obviously illegal immigrants and subsequent uneasiness about the potential theft of my rental car for their quick get-away. The latter was unfounded, as they were soon picked up by another car.

Birding was slow in the afternoon heat, so I decided to go to nearby Anzalduas County Park to look for the reported Rose-throated Becard. I joined a group of other birders in a search of the many trees in the vicinity of the restrooms, but all we could turn up besides Green Jays and Great-tailed Grackles were a flock of warblers of at least five species, including a lovely Black-throated Gray and a Pine. The couple from Massachusetts from the previous day showed up again, and they participated in the vain search. I then hopped into their car, and we drove up to the dam, where we missed the Cave Swallows that were supposed to be there. We found, however, a strange looking flycatcher the size of a pheobe, but with bright orange belly and breast, whitish throat, and a dark line through the greyish brown face. All I can think is that this was a male Vermilion Flycatcher molting into his first bright plumage. At about that time, we spotted a very gray hawk on a utility pole, which we first took to be a White-tailed Kite. However, it didn't have the black shoulder patches and actually turned out to be a beautiful Gray Hawk, a species that is known to nest at Anzalduas.

After that, I returned to Bentsen for another look around the trailer loop and a long chat with Pat Culbertson. At almost dark, I did the obligatory drive around the park roads and found a total of six Pauraqes resting on the warm asphalt, their eyes glowing red in the headlights.

Wednesday, November 17 - Santa Margarita Ranch - Falcon Dam and St.P.

This was my trip to western reaches of the Valley. Somehow, I got my instructions mixed up about the place where one can find Browns Jays early in the morning and ended up at the Santa Margarita Ranch instead of the trailers at Chapeno. Both places cost $2 per person to bird, but I'm sure the ranch is better for overall variety, even though the jay is not normally expected there. As described in the Lane guide and the Birding Map, wait for someone to shop up and take your money before getting out of the car, because of the pack of watchdogs.

Luckily, the latter didn't follow me down the obvious path to the river, where I birded for about three hours in light fog. Along the trail, I heard the whistled hoots of a Ferruginous Pygmy-Owl (familiar from hearing the tape many times at the King Ranch), and when I walked a few steps in the direction, I saw the bird fly out and into inaccessible areas. Many of the typical birds of the riparian forest were present, including Altamira Oriole, various doves, Plain Chachalaca, Green Jay, and the woodpeckers (including a Yellow-shafted Northern Flicker). One bird that I didn't get a good look at before it disappeared could possibly have been a Clay-colored Robin. I waited in the area for a long time, but it never showed again. In the drier areas toward the gate and the car were Verdins and Pyrrhuloxia.

On the way out, the fog lifted, and a sparrow flock at a cattle feeding cart caught my eye: the majority of them were Clay-colored Sparrows, with some Savannahs mixed in. Several Crested Caracaras flew around. At the overlook of the large Falcon Ranch pond I added some ducks and herons to the day list.

I reached the area beneath Falcon Dam when it became hot. Nevertheless, I walked all the way down to the abandoned hobo camp (an old clothes line is all that remains). I could have saved myself the long walk, as the most interesting bird was within 50 yards of the car: a Zone-tailed Hawk that I didn't see until it flew out of the trees where I was chasing some dicky birds (which turned out to be just Chipping Sparrows).

Falcon State Park was almost empty, except for the natural gas people. The lake water level was very low. A large flock of White Pelicans was near the Mexican shore, and several large flocks of Greater White-fronted Geese flew around. Otherwise, meadowlarks of probably both species were among the few birds in the picnic area.

After a nap, I went exploring around the boat ramp area and found a Rock Wren and some Horned Lark. A drive around the park revealed some Pyrrhuloxias and Curve-billed Thrashers, also four Northern Bobwhite at the only feeder in the trailer camp. I was assured at the visitor center that Cactus Wrens, a bird I was looking forward to seeing, were around, so I walked a ways along the nearby nature trail. I never found the wren but had great looks at a Black-throated Sparrow and some Verdins.

I timed the long drive back to McAllen such that I would arrive at the bridge over the Arroyo Salado west of Sullivan City at sunset. Pat Culbertson and others had assured me that this was the place to find Cave Swallows returning to their night roost under the highway. After some wait in the fading light and with heavy traffic roaring by, a high-flying flock of swallows appeared, circled high once or twice and then dove very under the road bed, not to be seen again. So this was yet another encouncter with what must have been Cave Swallows based on the location, but I didn't really feel that I had an identifying look at the birds.

Thursday, November 18 - Anzalduas Co.P. - Santa Ana N.W.R. - Areas North of McAllen - Back to Corpus Christi

On this last day in the Valley, I had a few holes to patch on my list: The rare Rose-throated Becard was tempting, and I had now good instructions, then there were Buff-bellied Hummingbird, Hook-billed Kite, Cave Swallow (for the satisfying definite look), and Cactus Wren. Clay-colored Robin was a long shot, and I didn't have time to go back to Brown Jay or White-collared Seedeater territory (Falcon Dam area).

My first stop was Anzalduas County Park, where I was assured that the Becard would be actively feeding early in the morning to become virtually unfindable later in the day. Sure enough, I found the male of the pair present in a tree very close to where I parked the car. I was able to show the bird to a couple of other birders before it disappeared into dense foliage. At the dam, two Cave Swallows performed as required, and I also found the out-of-range Black Pheobe that had been reported there.

I also had instructions on where to find the hummingbird at Santa Ana, so that's where I went next. Sure enough, after some waiting around the crabflower patch near the old rangers residence, the bird showed up and was well seen. I later learned that I could have also looked for a Rufous Hummingbird nearby. On the trail toward Pintail Lake, I was lucky again when a Hook-billed Kite flew over. The lake itself held a nice flock of American Avocet but not much else, in contrast to Willow Lake that was again full of ducks and shorebirds.

For the Cactus Wren, I had to find dryer areas, and I went looking for the dirt road a few miles north of La Joya known as "Sparrow Lane" (described in Lane Guide and the Birders Map). I didn't see any sparrows there, but a Cactus Wren indeed popped out of a bush when I stopped the car at a convenient place.

With this, I had exhausted all my likely life bird targets, and I drove around the agricultural area north of Edinburgh looking for other birds that were possibly new for the trip. Two Lark Sparrows near Hargill were the only trip birds, however, I got a nice variety of interestingbirds along the dirt roads in the patch of Lower Rio Grande Valley N.W.R. north of Hargill: White-tailed Hawk, Couch's Kingbird, and Vermilion Flycatcher, to name just a few.

After that, it was time to leave the valley for the long drive north on U.S. 281. At Falfurias (a town hit by a hurricane in September 1999) I cut over to U.S.77 along Hwy. 285 which is also known as "Hawk Alley". I didn't see any unusual concentrations of raptors, but a ranch pond along the road with ducks and shorebirds (possibly including Wilson's Phalaropes) made for some diversion.

I arrived in Corpus Christi after 4 pm, with just enough time for some coastal birding, which I did at the place that I already knew, Indian Point Park. I didn't add any new species to the trip list, but the combination of coastal birds with inland, Valley birds led to the largest day list of the trip, 105 species. The night was spent in Corpus Christi.

Friday, November 19 - Corpus Christi - Departure

From an excellent website maintained by Patty Beasley (known to many birdchatters for her daily reports from the famous fall hawk watch at Hazel Bazemore Co.P.), I had a good list of local birding hotspots. The two possible life birds were Seaside Sparrow and Gull-billed Tern, none of which I found.

The Hans A. Suter Wildlife Area was somewhat of a let-down, as it was almost impossible to get a view over the water of Cayo del Oso. The place is probably pretty good for passerine migration, but not in November. From the glimpses at the birds in the water I could tell that there were a lot of Avocets out there with the usual suspects.

The many stops along the North Padre Island causeway were more productive, with a similar species mix as Indian Point Park and good opportunities to photograph birds at close range. The entrance fee to the National Seashore was too high for at most an hour's visit, so I checked out a couple of the nearby county beaches, which were good for Sanderlings and some gulls and terns (but not Gull-billed). I never saw any suitable habitat for the sparrow.

On the way back to the airport, I stopped at Tule Lake for another look at a nice mix of shorebirds (frequently harassed by a Northern Harrier). The instructions on the website are accurate (except that there is no street sign for Corn Products Rd., but it's the intersection where you have to turn anyway), and the place is not all that difficult to find. A stop at a traffic light gave another opportunity for a look at some Bronzed Cowbirds together with their Brown-headed cousins. With the beginning of the Thanksgiving holiday season, the flights back to Chicago (layover in Houston, stop in St. Louis) were much more crowded than on the way there.

This species has just been declared "countable" as an introduced species by the American Birding Association (ABA) (Birding 1999 31(6), 518-524). It cannot be ruled out that some birds are of wild origin. Their natural range is shown by S.N.G. Howell and S.

  113. Ruby-throated Hummingbird - Archilochus colubris
    A female-plumaged Archilochus hummingbird at the entrance station at Bentsen was almost certainly of this species (11/16).

  134. *Cave Swallow - Petrochelidon fulva
    A flock of Petrochelidon swallows seen in poor light at Indian Point Park near Corpus Christi (11/11) was almost certainly of this species (the similar Cliff Swallow should long have migrated south). Another flock was seen after sunset disappearing under a bridge of U.S. 83 at Arroyo Salado west of Sullivan City, but no diagnostic marks could be distinguished. Finally, a few birds were seen well in broad daylight at Anzalduas Dam (11/18).

The bird actually flew underneath the car with me standing next to the door, landed on the hood, and started to peck at the area nearest the warning bell.
  147. Brown Thrasher - Toxostoma rufum
    Some of the thrashers at Laguna Atascosa (11/13) looked brown enough to be of this species, but at that time I wasn't familiar with the similar Long-billed Thrasher yet.
