Today's bird is the Summer Tanager! Summer tanagers live mostly in the southeastern United States with a little bit of overlap inthe New Mexico and Arizona. During migrations, they often pass through and a few sometimes even spend the winter here in the RGV. I think they're pretty awesome looking: the boys are fire-engine red like this one and the girls are a lovely yellow. You can tell the apart from other birds that may look or move similarly because of the big, thick bill.
I took this picture on October 8, 2012 at the Sheepshead lots on South Padre Island.
