Back in Texas, I frequently saw Kestrels catch grasshoppers. But best afternoon ever was at Tikal, years ago, watching two Bat Falcons dive from a temple roof comb and catch big bees. They use their feet; no "fly catching" for them.

If you see a Canyon Wren and a Bald Cypress together, you might be in Texas.
