Chaeturinae

Chaeturinae

 

a subfamily of birds of the order Apodiformes. The tips of the rachises of their tail feathers extend spikelike up to 1 cm and serve as a support for climbing in nesting places (cliffs, hollows, and chimneys). There are four genera, comprising 46 species; members of Chaeturinae are found mainly in the tropics and subtropics. There is one species, the needle-tailed swift, in the USSR.

Most authors consider that the lack of use of saliva in nest construction is a subfamily characteristic, in contrast to what is commonly seen in other Apodinae and Chaeturinae species (Lack 1956, Johnston 1961, Marin and Stiles 1992, Stopiglia and Raposo 2007).
Swifts of the subfamilies Chaeturinae and Apodinae, including White-throated Swifts, bring food to nestlings in the form of a bolus of aerial arthropods gummed together with saliva.
Black Swifts are capable of carrying a large mass of food in the esophagus for provisioning the chick, as opposed to a small bolus carried in the mouth, as in the Chaeturinae and Apodinae swifts (Collins 1998).
