Red-billed Curassow

Large, pale pigeon, unmistakeable if seen well, with large pale blue ocular ring and prominent white wing patches. Occurs in pairs or in small to large groups; mainly seen in trees, tops of cactuses, or in flight. Locally common in desert scrub, dry forests, and mangroves. Voice a very low “cooooo, tuk-tu-kUUuu, tuk-tu-kUUuu,” similar to other pigeons. The only pigeon with white wing patches in arid regions in its range.

Massive seabird of warm tropical oceans and coastlines. Overall black with extremely long, deeply forked tail and angular wings. Male completely black with inflatable red pouch on throat (not seen away from breeding colonies) and bluish eyering. In good light, black coloration can show purplish sheen. Adult female has white chest and golden bar on shoulder. Young birds have white head and breast. Often soars for long periods and flies with slow wingbeats. Steals food from other seabirds. Surprisingly acrobatic during aerial chases despite its large size. Limited range overlap with Great Frigatebird (mainly offshore western Mexico and in the Galapagos); identification is complicated by age and sex variation. Adult males are extremely similar; females and immatures best identified by exact pattern of white on head and breast, bill color, and eyering color.

A large, long-tailed bird of lowland and foothill forest. Blackish in plumage, with a bluish gloss on the back and a white tail tip. Note the wide red eye-ring, the yellow bill with red at the base, and the shaggy red crest from the crown. Forages in vine tangles for insects and other animal prey. Similar in size and shape to Scale-feathered Malkoha, but Red-crested lacks the obvious white hood. Call is a sharp “jok!”
