The kestrel caught its meal while hidden in the grass so I could not see exactly what it was, my guess would be a grasshopper. It flew down, caught it in a split second, then flew back up to the wire, you can see one set of talons curled around the prey in this shot. It perched with its back to me and ate the meal without letting me get a glimpse of it. Didn't take it long.
Female American Kestrel (Falco sparverius )
