Jacamar del paradiso

Identificazione

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.

Tassonomia

Early in the 20th century the paradise jacamar was placed in the monotypic genus Urogalba, but it has been in Galbula since the middle of the century. It has four subspecies, the nominate Galbula dea dea, G. d. amazonum, G. d. brunneiceps, and G. d. phainopepla. It is possible that they are actually clinal variations of one species.

Areale e habitat

The paradise jacamar is found throughout most of the Amazon Basin. The subspecies are distributed thus:<p>The paradise jacamar mostly inhabits terra firme, várzea, and savanna forests, both primary and secondary. It is also found in dry forest and gallery forest. It is most often found along edges or in open areas such as clearings and treefalls, and rarely in the forest interior. Unusually for a jacamar, it is mostly seen in the canopy rather than the mid level. It is most often found below 500 m (1,600 ft) of elevation but locally occurs up to 1,100 m (3,600 ft).

Comportamento

The paradise jacamar's diet is primarily Lepidoptera, Odonata, Diptera, and Hymenoptera, but it also takes other flying insects. It perches on exposed branches by itself, in pairs, or in small groups and sallies out to catch its prey. It sometimes joins mixed-species foraging flocks in the canopy.<p>A pair of paradise jacamars was seen excavating a burrow in an arboreal termite nest, and pairs have often been seen near such nests. No other information about the species' breeding phenology has been recorded.<p>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 [the] end" [1]. Its calls are variously "a single 'pip', 'peeap' or 'glewweh'" [2].
