Vagrant Rails and Crakes (Family: Rallidae) 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 vagrants of the family Rallidae (Rails and Crakes) in Sri Lanka.     

     1) Water rail (Rallus aquaticus) R.Indicus

3 or 4 specimens procured by Lieut. Long of H.M. Ceylon rifle regiment at Jayelle (Sic = Jaela) paddy-fields and given to Layard is the only record of the occurrence of this rail in Sri Lanka (Legge V. 1880: 1018).

Hitherto no records available on its early stages of life cycle or on larval host plants in published materials on Sri Lankan butterfly fauna. Recently egg laying and larva feeding on Terminalia catappa (කොට්ටම්බා) flowers were observed by Sujeewa Gunasena (Sujeeva Gunasena ‎ Personal communication, October 28, 2014 &  https://www.facebook.com/kamanijeeva/media_set?set=a.811498772250436.1073741853.100001709620688&type=1&pnref=story)

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 22^nd 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 19^th 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 28^th 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)

Possible range extension of Rasboroides nigromaginatus(?)

Note : - Sudasinghe et al., 2018 based on a phylogenetic study, resolved the issues raised in this post at    the end. Now Rasboroides nigromarginatus is considered as a synonym of Rasboroides vaterifloris

Sudasinghe, H., Herath, J., Pethiyagoda, R. and Meegaskumbura, M. , 2018, ‘Undocumented translocations spawn taxonomic inflation in Sri Lankan fire rasboras (Actinopterygii, Cyprinidae)’. PeerJ [Online journal], (20 December 2018). Link >>

Endemic genus Rasboroides is restricted to the shaded rain forest streams of South-western wet zone from Kalu to Walawe drainages.  A single species of Rasboroides formerly known as Rasbora vaterifloris was divided into four different species recently base on morphological differences. Table 1 summarized some of their morphological features with distribution in the country base on Batuwita S. et al., 2013. 

Rasboroides nigromarginatus (Black Line Golden Rasbora/කලු-ඉරි හල්මල්දන්ඩියා[Kaluiri Halmaldandiya])

Rasboroides nigromarginatus was first described by a German scientist H. Meinken in 1957 as a new species base on a single specimen collected from the ‘Ceylon’ without knowing exact locality. He had found that specimen among some exported ornamental fishes from Sri Lanka and considered it as a synonymy of Rasboroides vaterfloris (Deraniyagala, 1958 & Pethiyagoda, 1991). It has not been collected since then until the rediscovery in 1994 from Athwelthota by R. Pethiyagoda & K. Manamendra Arachchi and independently in 2010 by members of Wildlife Conservation Society, Galle. 

With the recent review of Rasboroides group it is now considered as a valid species occurs only in Athwelthota area of Kalu river basin. Here we record a possible range extension of this species again on Kalu river basin but considerable distance away from the type locality.  We would like to keep exact locality undisclosed, considering past experiences of   extinction of some rare endemic fish species from certain localities without proper protection, due to excess collection for export and local ornamental fish industry (Ex. Extinction of bright color Rasboroides species from Puwakpitiya Dola in Indikada Mookalana and total extinction of them from Madakada Mookalana - Chamikara S., 2012).  

We were able to observe and photograph four live specimens of Rasboroides in a tributary of Kalu River in the Kiriella area of the Rathnapura district.  The stream is bordered to a rubber plantation but with well wooded  banks with several indigenous plants. One specimen we observed was bit bigger than other three and lack black color of un-branched ray of dorsal and other fins on the leading edge (However it is slightly visible on the dorsal fin ray on nearly half of its length – See picture).  But three small specimens had prominent black lines along leading edge of all their fins. Other than that large specimen was more yellowish on its dorsal and upper half of the side and fins while small specimens had more silver in dorsal as well as venter and sides.  However orange red color of dorsal fin and orange of caudal fin was not observed in any specimens. Taking accurate measurements of the specimens was impossible with living fishes due to obvious reason. But approximate size of the large specimen was visually estimated as 30mm and about 20mm of small three.  Body depth of all 4 specimens was around 30% SL.

Three out of four species of Rasboroides have been recorded from Kalu river basin and R. vaterifloris reported from Small shaded streams and rivulets in and around Gilimale is the closet Rasboroides locality recorded so far to the locality of the current specimens. However morphological features of them much resembles to the R. nigromaginatus hitherto only recorded from Athwelthota area.  
     Is this a hybridization of R. nigromaginatus and R. vaterifloris? Why only small individuals have prominent black ray on leading edges of fins? Are they juveniles and would it be faded away in adult specimens?  Or we are here dealing with two different species (We have observed that small individuals are schooling separately during our observation)? More research need to be done before come to a conclusion especially with exact measurements and scale counts with preserved specimens. But which is beyond our scope and for the time being we would like just to report this observation and highlight the need of conducting more research on our ichthyofauna and also most importantly conserving of their habitats with special consideration towards the streams and rivulets outside the protected forest reserves in Southwestern wet zone of the country.  Because those water sources are highly vulnerable to the human activities (We got to known that excessive fishing have been practicing in above area some time even with using explosives which destroy every living inhabitants of the stream from big to small). There are enough possibilities of discovering new species not only of fishes but also other animals as well in these unprotected areas and it is needed to conserve them before those ‘to be discovered’ species would be vanishing from the world before even known to the scientific community.
