Красногрудый зимородок Megaceryle torquata

Largest kingfisher in Americas with exceptionally enormous bill and raucous calls. Blue-gray with shaggy crest, white collar, and rufous belly. Male and female similar, but note different breast pattern: entirely rufous on male, while female has blue-gray band bordered by white. Often conspicuous, searching shallow water for fish from a prominent perch and chattering noisily when disturbed. Singles or pairs are also often observed flying high overhead and giving loud "keck" calls. Nests in burrows excavated in banks, generally along watercourses.
