Eastern Bluebirds do not breed in the Rio Grande Valley but they always seem to be present at the Falfurrias Rest Area which is about 60 miles north of McAllen. I need to spend some time up here in the summer to see what's going on.
Most winters a Yellow-throated Warbler can be found with the Orange-crowns and Yellow-rumps.
A couple of Blue-headed Vireos turned out to be my first in Brooks County. Not sure how I've missed them in the past.
Audubon's Warbler seems to be regular here in winter.
On the way up I stopped at the old picnic area on US 281 right before the Brooks County line. I found a few sparrows, including this Grasshopper Sparrow, but not the Field Sparrows I had hoped for.
And a nice female Pyrrhuloxia.
