treeswifts
crested swifts
hemiprocnidae latin

It is in the order Apodiformes with treeswifts and hummingbirds.

Altogether, they were not too dissimilar to modern treeswifts.

The treeswifts exhibit a wide range of habitat preferences.

Unlike the true swifts, the treeswifts readily rest on high bare tree branches.

Treeswifts are small to medium sized swifts, ranging in length from 15-30 cm.

Swifts' nearest relatives are thought to be the New World hummingbirds and the Southeast Asian treeswifts.

Treeswifts or crested swifts are a family, Hemiprocnidae, of aerial near passerine birds, closely related to the true swifts.

The latter group is sometimes controversially included in the Aegialornithidae, as are the Jungornithidae, another prehistoric apodiform family that was somewhat intermediate between treeswifts and hummingbirds.

However the latest studies do not agree with this arrangement as these studies show turacos relatively close to Aequornithes (which include birds such as loons and herons) and the caprimulgiforms are more likely a paraphyletic lineage within Cypselomorphae (which also include the apodiforms, the hummingbirds, the swifts and treeswifts).

For instance, instead of putting the swifts, treeswifts, and hummingbirds in the same order that includes nothing else, Sibley and Ahlquist put them in the same superorder that includes nothing else, consisting of one order for the hummingbirds and another for the swifts and treeswifts.

Treeswifts or crested swifts are a family, Hemiprocnidae, of aerial near passerine birds, closely related to the true swifts.

The hummingbirds, swifts and crested swifts share other anatomical similarities with one another as well as similarities (notably as to the skull) with their probable closest living relatives, the owlet-nightjars (Mayr, 2002).

The Whiskered Treeswift (Hemiprocne comata) is a species of bird in the Hemiprocnidae family.

Treeswifts or crested swifts are a family, Hemiprocnidae, of aerial near passerine birds, closely related to the true swifts.

Other endemic Asian or mainly Asian families include Acrocephalidae, Aegithalidae, Certhiidae, Cettiidae, Chloropseidae, Dromadidae, Eupetidae, Eurylaimidae, Hemiprocnidae, Hypocoliidae, Ibidorhynchidae, Muscicapidae, Phasianidae, Pityriaseidae, Podargidae, Tichodromadidae and Turdidae.
