A closer look at a Whiskered Treeswift

posted in: Morphology-Develop. | 0

The Whiskered Treeswift (Hemiprocne comata) is a forest bird. It is usually seen high up in the forest canopy, among the tall emergent crownsas wee as along the forest edge. Occasionally it descends lower to secondary forests and matured orchards. It perches near the ends of bare twigs of tall trees looking out for small flying arthropods.

KC Tsang managed to capture the above image at the Ulu Temburong National Park, Brunei Darussalam in September 2013.

Noted KC, “I would like to venture to say that not many people would have seen the back view of this very handsome bird, the Whiskered Treeswift…”

Another image that KC captured is the treeswift turning 180º such that it is able to see behind (above). An earlier post LINK describes how the long neck folded into an s-shape enables the bird to pull such a stunt. The Common Kingfisher (Alcedo atthis) has similar ablilty LINK.

On the other hand, owls are able to turn up to 270º in either direction LINK.
