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:

ImageScientific nameCommon NameDistribution
Galbula albirostrisYellow-billed jacamarBrazil, Colombia, French Guiana, Guyana, Suriname, and Venezuela
Galbula cyanicollisBlue-necked jacamarAmazon rainforest of Brazil, far northern Bolivia and eastern Peru
Galbula ruficaudaRufous-tailed jacamarsouthern Mexico, Central America and South America as far south as southern Brazil and Ecuador
Galbula galbulaGreen-tailed jacamarBrazil, Colombia, French Guiana, Guyana, Suriname, and Venezuela
Galbula pastazaeCoppery-chested jacamarsouthern Colombia, Ecuador and far northern Peru
Galbula cyanescensBluish-fronted jacamarwestern Amazon Basin of Brazil, Peru and far northwestern Bolivia.
Galbula tombaceaWhite-chinned jacamarAmazon Basin of Colombia, Amazonas and northern parts of Ecuador and Peru
Galbula chalcothoraxPurplish jacamarwestern Amazon Basin of Ecuador, Peru, southern Colombia and western parts of Acre and Amazonas
Galbula leucogastraBronzy jacamarBolivia, Brazil, Colombia, French Guiana, Guyana, Suriname, and Venezuela
Galbula deaParadise jacamarBolivia, Brazil, Colombia, Ecuador, Peru and the Guyanas

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.
