Paradise Jacamar
Galbula dea
The paradise jacamar is 25.5 to 34 cm (10.0 to 13.4 in) long and weighs 25 to 32.5 g (0.88 to 1.15 oz). Both sexes of the nominate have a dark brown crown and are glossy black on the rest of the upper parts. They have a white throat and upper breast; the rest of the underparts are blackish. The other subspecies differ in a few ways. G. d. amazonum's crown is lighter and the white throat more extensive, and G. d. phainopepla is similar to it. G. d. brunneiceps's crown is lighter and its upper parts have a bronzy greenish sheen. Voice: The paradise jacamar's song is "a well-spaced "peep peep peep peep peep peep pee pee pe pe", usually descending, becoming slightly faster and weaker towards end" . Its calls are variously "a single 'pip', 'peeap' or 'glewweh'" .
