Brown-backed Needletail

Hirundapus giganteus

The brown-backed needletail, known scientifically as Hirundapus giganteus, is a remarkable avian species. This large swift, measuring an impressive 23 cm in length, is notably larger than its relatives, the Alpine swift and the white-throated needletail. It possesses a robust, barrel-like body and is predominantly dark brown in coloration, with a distinctive white undertail that extends onto the flanks. The species is aptly named for the spined ends of its tail, which, unlike the forked tails of typical swifts in the genus Apus, are not forked.

Identification Tips

When observing the brown-backed needletail, one should look for its heavy-set body and rapid flight, which is swift even by the standards of its family. The white undertail and flanks are key identification features, contrasting with the bird's otherwise dark brown plumage. The tail's spined ends are another characteristic to note, though they may be less visible in flight.

Habitat

These swifts are known to favor hill forests, where they are resident breeders. They have a strong affinity for vertical surfaces, which is reflected in their choice of nesting sites.

Distribution

The brown-backed needletail can be found across southern Asia, with its range extending from India to Indonesia and the Philippines.

Behaviour

This species is highly aerial, spending the majority of its life on the wing. It exhibits a remarkable adaptation in that it seldom, if ever, lands voluntarily on the ground. Instead, it uses its very short legs primarily for clinging to vertical surfaces.

Breeding

The breeding habits of the brown-backed needletail involve constructing nests within rock crevices found on cliffs. They are known to lay clutches of 3-5 eggs.

Similar Species

While similar in build to the white-throated needletail, the brown-backed needletail can be distinguished by its larger size and the white pattern on its undertail and flanks.

Diet and Feeding

Insects form the dietary staple of these swifts, which they adeptly capture with their beaks while in flight.

Conservation status

The IUCN Red List has classified the brown-backed needletail as Least Concern, indicating that, at present, the species does not face an immediate threat of extinction.

The best bird logging app
Birda is honestly the best bird logging app I have seen. I love all the features it has from being able to do a session and log all the birds you see in one sitting, to being able to connect with other birders from all over the globe!

We've been waiting for an App like this
Excellent! We've been waiting for an app like this! Thank you! It would be nice if you could assign additional birds to sessions later!

Simply fantastic
I love this app, it puts so much fun into recording the birds I’ve seen and heard while I’m out and about. The interface is user-friendly and suitable for all ages. It’s great to collect badges and to review my “lists”.

Just what birding needs
We need more fun in birding, for years it has had a reputation for being up tight and stuffy and only perused by retirees and anoraks. Birda helps change that perception and firmly brings birding into the 21st century! Fun, interactive while still contributing to science and conservation. If you aren’t on it, why not??

Great app for bird lovers
I love this app! It’s a wonderful way to track birding sessions, and also connect you with fellow birders. I also really like the unidentified bird section, it’s a great community tool to help figure out what a never-before-seen bird is!

Clean and easy to use
Really enjoying this app, it's clean and easy to use. I love the ease of being able to add those one-off birds without starting a whole checklist. I also like the social aspect, like the parts of my Facebook I like, without the ads and junk, just birds. Can't wait to see it become more populated.
