****PHOTOS TO COME ONCE I GET HOME
I just made a brief down to the lower Rio Grande Valley in Texas starting on Wednesday and continuing through early Saturday. I made the trip mainly to try to track down a couple warbler species with the main one being a Tropical Parula for me in the US (I have seen the species many times in the tropics) and the other being a Mangrove Yellow Warbler. I arrived into Harlingen in the middle of the afternoon on Wednesday and then made the drive down to my Airbnb in Brownsville. The weather was very windy and warm when I arrived and these conditions unfortunately continued every day. By the time I drove down, did some shopping and dropped off my stuff at my Airbnb it was late afternoon. Although I didn’t think I would have much luck so late in the day with the wind I made a trip down to the UTRGV to try to locate one of two male Tropical Parula known to be at the site. As expected the wind was just too strong and there was little activity during my stop. At least I was able to recon the area a bit so I would know how to get around on the following morning.
On Thursday the 19th I was out before dawn and headed back down to the UTRGV campus. The wind was still strong before the sun came up and continued for my entire time there. Once it brightened a bit I started getting some warblers with the first being Common Yellowthroats and then Yellow rumped Warblers (mainly Myrtle’s with one Audubon’s) plus some Orange crowned Warblers and a Yellow throated Warbler. I then caught sight of a male Tropical Parula and then a Yellow rumped chased it away. One target down and my 51st warbler species ever in the US. I then spent the next two plus hours trying to relocate the bird to get photos with no luck with that. However I did keep finding warblers and eventually had a dozen species including other notables for the area like American Redstart and Tennessee Warbler as well as a female Tropical Parula x Northern Parula hybrid. The small area was really great for warblers with a dozen species and I can only imagine how much better it would be when there is no wind. With my target Tropical Parula seen and not reappearing for photos, I decided to make the 45 minute drive out to South Padre Island and try my luck in finding a Mangrove Yellow Warbler. Once again I had some great tips from Aidan on where to try for the bird and most importantly where to park. Once I crossed over the causeway to the island I quickly found multiple Mangrove Yellow Warblers and got some photos of this recently split species. There were at least three present with a couple singing occasionally and I got some crappy recordings. I have seen the species extensively in the tropics but only once before in the US and that was in Florida where the species does not have the full rusty head like the subspecies in far south Texas. I also added a Northern Waterthrush for the day in the mangroves and my total number of warblers for the day finished at 14 with four of those new for the year for me….my best warbler day for the year so far. I considered heading back down to the campus to try to get photos of the Tropical Parula late in the afternoon once I was back at my Airbnb but honestly I did not relish dealing with the absolutely shitty roads of Brownsville. The roads in Brownsville are a mess with poor conditions and signage and reminded me more of driving in a third world country than the US.
For my last full day in Texas on Friday I headed west to visit a few spots away from Brownsville. There had been a female Tropical Parula seen at Estero Llano Grande SP so that gave me a good excuse to head there. During previous trips to the valley I found the park to be very productive and it once again produced some good stuff. I arrived before dawn and was able to start exploring the park right away. I walked a variety of trails before making it to the area where the Tropical Parula had been seen. It was overcast with fairly light winds early on and was a nice break from the winds…the mosquitoes unfortunately loved the conditions too and they were a bit of a bother. The parula had been reported coming into a water drip set up so that is where I waited for it. After about 15 minutes a group of birds were moving through the dense vegetation near the drip and included two Orange crowned Warblers, a Nashville Warbler and the Tropical Parula. I got brief looks at it and I hoped it would come down to the drip but that was not to be. Eventually the Orange crowned Warblers came down and enjoyed the water. I waited for over 45 minutes and then checked some nearby areas without every seeing the parula again. The park produced five species of warblers during my time there. The sun was breaking through as I was leaving to make a stop at Santa Anna NWR and the temps jumped into the 80’s quickly and the damn wind picked up. The refuge was very quiet so I left to work my way back toward my Airbnb. With the slightly less windy conditions present I decided to drive directly back to the UTRGV campus to try to get photos of a Tropical Parula there. Despite spending three hot hours looking and listening I never did see the Parula for certain…I had a brief view of a warbler getting chased by a Yellow throated Warbler and Black throated Gray Warbler that may have been the parula. It was still worth the stop even without getting the parula as I had eleven species of warblers including a couple unusual species including American Redstart and Tennessee Warbler. By the end of the day I found a dozen species of warblers.
I had a late morning flight out of Harlingen on my way to Arizona on Saturday and I was only able to get a little birding in before heading to the airport. I decided to try my luck at Hugh Ramsey Park which is not too far from the airport. I arrived there before dawn
Overall for the trip I found a total of 15 species of warblers with five of them new for me in Texas (Yellow throated Warbler, Tropical Parula, Black throated Green Warbler, Mangrove Yellow Warbler and Northern Waterthrush).
The short trip produced four new warbler species for the year for me and brought that total up to twenty species.
