Streamlined long-winged falcon. Note gray upperparts with plain tail, boldly streaked underparts with rusty leggings and vent. Swift-like; flight more graceful and aerodynamic than Eurasian Kestrel. Compare with larger, stockier, shorter-tailed Peregrine Falcon. Favors open woodland, heathland, and farmland with stands of trees; often hunts over nearby water bodies and marshes. Hunts in the air, catching dragonflies, swallows, and other birds, which it sometimes eats on the wing.
