Blyth's Swift (Apus leuconyx)

 Very rare vagrant bird with few sight records in Sri Lanka. Blyth's Swift breeds in Himalayas from Murree Hills to Assam valley and in South Assam Hills and is a winter visitor to India, Bangladesh and Sri Lanka. As it is with all other swifts, Blyth's Swift feeds entirely on flying insects.

Indian Swiftlet/ඉන්දු උප තුරිතයා/කැදලි තුරිතයා [Indu Upa Thurithaya/Kedali Thurithaya] (Aerodramus unicolor)

 

A fairly common breeding resident, locally occurred throughout the country over towns, open country and forest canopy. But it is much common in the hill country. It feeds mainly on flying insects as flocks, sometimes in company with other swifts. The breeding season appears to be in the first half of the year and probably again from August to September. It build a nest, a small half cup constructed with its own saliva, more or less mixed with moss and other fibrous materials, affixed to the surface of a ledge or the sloping roof of a cave, railway tunnel, culvert or such a place. It lays two eggs and half grown young birds seems to be prefer clinging to the outside of the nest. Indian Swiftlet use same caves for breeding as well as for the roosting as large colonies and always choose darkest part of the cave for the nest.

Brown-backed Needletail/කටුපෙඳ තුරිතයා/පිටබොර කටු-තුරිතයා [Katupenda Turitaya/Pitabora Katu-Turitaya] (Hirundapus giganteus)


 Rather uncommon breeding resident, locally occurs throughout the island, mainly in the rain forest areas though visit open country and forests in other areas. It lives as small flocks or as solitary birds and feeds  entirely on flying insects. Brown-backed Needletail breeds from February to April (Harrison J. & Worfolk T., 2011) or August-September (Henry G.M, 1998 & Kotagama, S., Ratnavira, G. 2017) in a big, hollow forest tree. It enter by a hole near the top of the trunk and deposit three to five eggs, without any nest in the bottom of the cavity, often at ground level or even below (Base on Indian observations and so far no nest has been described from Sri Lanka).

Alpine Swift/මහ තුරිතයා/ඇල්පයින් පිරි-තුරිතයා[Maha Turitaya/Alpine Piri-Turitaya] (Tachymarptis melba)

 Rather rare breeding resident inhabiting hills and foot hills. But can be occurred anywhere in the island. It flies as solitary birds or as small flocks, usually with other swifts and feeds entirely on flying insects like moths, beetles, etc. Alpine Swift select cracks and crevices of large rocky areas for roosting and nesting. Nesting period appears to be in the first half of the year. The nest is a shallow cup of straws, feathers, etc. stuck together with its own saliva and glued to wall of crevice or cave on cliff.  It lays probably two or three eggs in it.

Little Swift/House Swift/White-rumped Swift/කළු තුරිතයා/පුංචි තුරිතයා [Kalu Thurithaya/Punchi Thurithaya] (Apus affinis)

 

Common breeding resident locally occurs from lowlands to higher hills, often near large rocky outcrops. It usually speeding through the air in search of small flying insects, as large scattered flocks, often with other species of swifts and swallows. Flying insects form their main food. The breeding season is during the first half of the year and the nest is a large cup shaped structure made up of grass, straws and feathers glued together with the bird's saliva and stuck to the roof of a cave or underside of a bridge or the like. They breeds in colonies and often use nests for the roosting as well. So birds frequent at their nesting places all the year round.

Vagrant Swifts (Family: Apodidae) recorded in Sri Lanka

Birds that appear outside their normal range are known as vagrants. This post summarizes up to date published sight records of four unconfirmed vagrants* of the family Apodidae (Swifts ) in Sri Lanka.

*Species for which there are only one or two sight records exist categorized here as unconfirmed vagrants. Problematic records without sufficient details are also included.

1) White-throated Needletail (Hirundapus caudacutus)
Amila Salgado reported a sight record of White-throated Needletail first time in Sri Lanka in Pokunutenna (located in the North-Eastern boundary of the Udawalawe national park) on 22nd February 2007. He had observed several of them in a flock of swifts which included little swifts, Indian swiftlets and Asian palm swifts. He has also mentioned about a sight record of this swift in 2003 at Sinharaja by a visiting bird watcher though which was not reported formerly (Salgado A., 2007). A sight record of two White-throated Needletails on 19th February 2003 in Sinharaja is mentioned under ‘List of rejections (after 1990)’ of Ceylon bird club (http://www.ceylonbirdclub.org/List-of-Rejections.pdf). This is probably the same sight record Salgado was referring above.

     2) Pallid Swift (Apus pallidus)
A swift probably of this species was photographed in South-east Sri Lanka (Rasmussen P.C. and Anderton J.C., 2012: 259-260)

     3) Fork-tailed Swift [Pacific Swift/Large White-rumped swift] (Apus pacificus)
First record in Sri Lanka by Deepal Warakagoda from Bundala national Park in 28th November 1996 (Hoffmann, T. W., 1997 & Warakagoda, D., 1999).  A sight record by M.J. Pointon (UK) at Bentota in December 1997 is the second record of it in Sri Lanka (Hoffmann, T. W., 1999). However another record is given as the second report of it in/near Yala Block 1 by Warakagoda D. & Sirivardana U. in the summery of bird club notes for 2008-2010 periods (Warakagoda D. & Sirivardana U., 2011)

     4) Dark-rumped Swift (Apus acuticauda)
A sight record at Kandy in February 1993 by A.J. Vincent is the only record (Kotagama S. & Ratnavira G., 2010: 257)

Asian Palm Swift (Cypsiurus balasiensis)



Common breeding resident in low country and lower hills especially where palm trees such as Palmyras or Talipots are available.  It keeps in flocks and spends its time flitting about in open areas in search for small flying insects. It breeds probably year round and the nest is a small cup of feathers and cotton, glued with its saliva under fan-palm leaf or occasionally the fronds of the Areca or Betetnut palm (Only if no fan-palm is available).
