It looks like this individual has a full crop! Taken during the Cibolo Bioblitz on 10/10/2015. This was the last day of their twice-per-year week-long Wildlife Field Research Week.
Red-shouldered Hawk in flight over Mound Meadow
Pair chased off an Osprey on Sims Bayou trail off Airport and MLK Jr Blvd
As I was approaching some tall grass and weeds in the Lake Creek Branch greenbelt park I heard a big commotion. When I looked toward the noise I saw a big hawk flying away with a snake in its grasp leaving behind a cloud of dust. It landed in a willow tree branch not far away where I took these photos.
The snake was about 3 feet (1 m) in length and dark on top and lighter underneath, but I'm not sure what kind it was.
Red shouldered hawk
The Red-shouldered Hawk (Buteo lineatus) is a medium-sized hawk. Its breeding range spans eastern North America and along the coast of California and northern to northeastern-central Mexico. Red-shouldered Hawks are permanent residents throughout most of their range, though northern birds do migrate, mostly to central Mexico. The main conservation threat to the widespread species is deforestation.
