Texas: Old Port Isabel Rd to Mexico
Heavy fog rolled in the next morning but it didn’t take long for the blazing sun to burn it off. The Lower Rio Grande Valley is hot. Each day I dug deep to my Floridian roots, sucked it up, and birded through the thick wall of humidity and heat. While applying regular applications of sunscreen and bug spray. It’s easy to forget that trying daily routine from the (mostly) comfy Pacific NW.
But of course the same reasons I’m repelled from the southeastern US are what attracts such a great diversity of birds. Heat and bugs. We had plenty of both at our next Texas hotspot, Old Port Isabel Road, seven miles of gravel road through lowland open grassland habitat.
One of the first bird’s to greet us was the Eastern Meadowlark.
I recognize that shape. This meadowlark is best distinguished from the Western variety by song. Western: a rich, low, descending warble “sleep loo lidi lidijuvi.” Eastern: simple, clear, slurred whistles “seeeooaaa seeeeadoo” higher, clearer, with no gurgles (Sibley 2016).
Shortly after we heard another tell-tale “Bob-white” call of the Northern Bobwhite! This was one of my most eagerly anticipated sightings. So cool. Even if they just ran away from us.
Then someone spotted a White-tailed Hawk far in the distance. Worst views ever so here’s a slightly less worse view from a later sighting. Clearly white-tailed.
I should mention another hawk of Texas that should have been familiar but wasn’t.
Red-tailed Hawks. Like the one below. Where are the patagial marks? It doesn’t match Eastern or Southwestern varieties in guidebooks. Leave it to red-tails to break the mold. Jerks.
At least Harris’s Hawks follow the rules. And there were plenty of these along the road.
Not just raptors, there was also a fun new sparrow to ID, the Olive Sparrow. It has one of the greatest sparrow songs I’ve heard with a catchy bouncy-trill ending.
Near the end of this road we all got a great surprise on a telephone pole.
Mythical falcons seen only in guidebooks come to life. Aplomado Falcons! (Aplomado Spanish for “lead-colored”). Then they did what no birds ever do. They both flew directly towards us.
They passed us by at eye level flying incredibly fast and low over the prairie.
It was absolutely stunning. There’s some controversy about “counting” this species for checklists; they currently meet the ABA checklist requirements but “Texas Bird Records Committee (TBRC) currently considers the reintroduced population of Aplomado Falcon to be not established, nor self-sustaining and thus deems this species not countable.”
The last wild breeding pair was seen in New Mexico in 1952. These that we saw are a result of a falcon-reintroduction program by the Peregrine Fund. Thanks to predator-resistant nesting platforms and the release of 1,500 chicks (since the 80s) there is now a small breeding population in this part of Texas.
I’m grateful because either way you count it, the falcons are amazing. And since it’s my 400th bird species they count extra for me.
What happens after an Aplomado sighting? We could have ridden the high the rest of the day but it was still early. So we did the only thing we could do. We headed to South Padre Island for 0.99 beer bongs.
Jk. We birded on. The afterparty started at the South Padre Island Birding and Nature Center where a white-morph Reddish Egret drunkenly danced in the tides.
An Osprey danced with a Northern Mockingbird.
Black Skimmers danced in the sky.
And gators sat stoned grinning in the corner.
We also saw Scissor-tailed Flycatchers aka wallflowers.
And Little Blue Heron and Tricolored Heron doing The Robot.
It was good times. We took a break from partying and birded near a random boat ramp.
Among other shorebirds, we found a Wilson’s Plover under the only bit of shade around.
Then there was time for one last stop. Mexico. Or at least up to the border. This took some confident driving skills by Jen.
At least the tide was going out. Right? Then, before picking out birds in Mexico, finding a dead dolphin on the beach, laughing at cartoon crabs and watching Max catch a fish with his bare hands, we had the second most exciting bird encounter of the day. AJ yelled for us to look at the dark bird over the water!
We all turned to see a Parasitic Jaeger chasing after a Sandwich Tern!
But you can’t see jaegers from the shore?! These are pelagic birds! You have to be seasick on a boat miles off shore to see them!
Except when you’re in Texas. Aplomado to Jaeger in a day? The tropics are growing on me.
Birders gone wild,
Holy Hot Wire! That one electric line just kept on dishing up great raptors! How can they say these introductions are not successful, Im sure it was the hand of man that depleted them and now they are resurrected by the same so one cancels out the other. Check the box!!
Wow on the Jaeger I def would have seen this and thought it was some kind of weird sea gull, so I must study it well JIC!
So much dancing on South Padre, and no beer bongs involved. Though for only 99 pennies we probably should have picked one up. I missed those herons doing the robot. Sad face.
Could that rule-breaking red-tail be a Swainson’s?
Funny you should say that! This was that hawk at Estero (the first round when we were looking for the becard). Swainson’s came up- “but that belly band” swayed discussion to immature weird Texas red-tailed. But it could be weird Texas Swainson’s? I’m open. It’s a jerk either way.
