We didn't get a good enough look at several other birds for a confident ID. We saw some doves, but think they were Mourning Doves. There were lots of Grackles, including the Boat Tailed Gackles we always find in Texas. A Cooper's Hawk strafed the arroyo several times, and a large flying bird turned out to be a Roseate Spoonbill! We kept hearing a soft chucking sound in the grass and brush, and hoped it was a Chachalaca, but will keep trying until we are sure. This nature center was in the middle of Harlingen, and had no trail maps available, so we just asked dog walkers how to get back to the parking lot. Thank goodness we found the motel before going birding. If we waited until dusk, we never would have found it!
Total for today - 16 birds in about 1.5 hours including 4 lifers. It's going to be a great vacation!
