タニシトビ Rostrhamus sociabilis

Unique snail-eating raptor. Widespread and fairly common in Central and South America, but very limited range in U.S. Found exclusively around lakes and marshes with plenty of vegetation. Adult male is entirely dark gray with red eyes, orange feet and base of bill, briefly turning red in breeding season. Females and immatures are streaky brown. Note very sharply hooked bill, long broad wings, and short dark tail with a white base above and below. Look for pairs or small groups flying over marshes with slow, buoyant wingbeats. Frequently perches on bushes.
