Galbula is the type and largest genus of the jacamar family (Galbulidae) of piciform birds, and its suborder Galbulae. Sometimes, the Piciformes are split in two, with the Galbulae upranked to full order Galbuliformes.[1]
They are smallish to mid-sized forest birds of the Neotropics, with long pointed bills, elongated tails, and small feet. Colored in metallic iridescent hues – typically greenish – at least on the upperside, some have a red or brownish belly. Males and females are generally similar in appearance, but in most species differ in minor plumage details. As usual for Piciformes, they nest in burrows they dig out themselves. In the case of this genus, nests are dug in earthen banks along rivers or roads, or in termitaria. As with other jacamars but otherwise unknown among Piciformes, their chicks do not hatch naked. They have a piping song and feed in typical jacamar fashion, by catching flying arthropods, typically larger insects such has butterflies.[1]
Most Galbula species are fairly common in their natural range, which despite rampant deforestation is still extensive. Only the coppery-chested jacamar (G. pastazae) occurs in a more restricted region in the Andes foothills, and is considered a threatened species.[1]
Species
Ten living species are presently recognized in this genus, and it is not very likely that this will change much. Listed in the presumed phylogenetic sequence, they are:
- Yellow-billed jacamar, Galbula albirostris
- Blue-necked jacamar, Galbula cyanicollis
- Rufous-tailed jacamar, Galbula ruficauda
- Green-tailed jacamar, Galbula galbula
- Coppery-chested jacamar, Galbula pastazae
- Bluish-fronted jacamar, Galbula cyanescens
- White-chinned jacamar, Galbula tombacea
- Purplish jacamar, Galbula chalcothorax
- Bronzy jacamar, Galbula leucogastra
- Paradise jacamar, Galbula dea
A fossil species, Galbula hylochoreutes, has been described from the mid-Miocene of Colombia. It was apparently more specialized for aerial feeding than the living species.
