The Dollarbird, Eurystomus orientalis is one of the rarest and endangered bird in Sri Lanka. During a pilgrimage to Ambulgala Rajamaha Viharaya on 6 July 2009, one individual of dollarbird was sighted at Ambulgala (6° 54’ 20.98” N, 80° 03’ 03.01” E) between Hanwella and Ranala around 17:20 h. The dollarbird perched on a branch of a Jack tree (Artocarpus heterophyllus) around 10 m from ground level. During 40 minutes the bird flew away two times and came back and perched on the same tree. The villagers reported that the bird has been roosting on the same tree for past two months. Dollarbirds have been previously reported from many locations, but this is the first record from Colombo District, which is 40 km away from the nearest previous record from Kalutara District, Sri Lanka.

The Kandyan Shrub Frog, Pseudophilautus rus is known only from two localities around Kandy (500–800 m a.s.l), Sri Lanka; Kiribathkumbura and Pilimatalawa. Mature males attain a SVL of 20.6–24.1 mm and mature females up to 23.1 mm. P. rus perches on low vegetation, usually on leaves and branches of shrubs, grass, and logs, 0.1–1.5 m above the ground. Males of the species produce one of the most frequently heard calls in suburban and urban areas in Kandy, together with the common shrub frog P. popularis. Here, I describe for the first time the advertisement call of P. rus.

Three tick species parasitizing a rock python in Sri Lanka

Parasitism is a relationship where one of the parties (the parasite) either harms its host or lives at the expense of it. Host parasite interactions are important driving forces in population dynamics and even extinction. These interactions are also indicators of ecosystem health and they are important in stabilizing food webs. A parasite may cause mechanical injury, stimulate a damaging inflammatory or immune response, or simply rob the host of nutrition. However in the wild most parasites must live in harmony with their hosts. If the parasites kill the host, they themselves would ultimately die without shelter and nutrition. Reptiles become hosts to a number of parasitic organisms ranging from protozoans to arthropods. Among these, ticks (hard and soft) are the most common arthropod group that parasitizes reptiles.

First record of the blue sea slug (Glaucus atlanticus) from Andhra Pradesh – India

The blue sea slug Glaucus atlanticus Forster, 1777 (Gastropoda, Glaucidae) is a nudibranch that occurs in temperate and tropical oceans throughout the world. It is characterized by a silvery white dorsal surface and dark blue ventral surface. The body is elongate measuring up to 3 cm and is flattened. The head is small and blunt with a pair of small oral tentacles near the mouth. The cerata or papillae are wing-like and extend laterally from three distinct pairs of peduncles. The papillae are placed in a single row (uniseriate) and may be 84 in total. A similar looking glaucid nudibranch, Glaucus marginata (Bergh, 1860), is a bluish-brown nudibranch with bluish underside, and differs from Glaucus atlanticus in bearing four pairs of clusters of papillae that are arranged in more than one row (multiseriate) and may be 139 or more in number. The latter species has been included by some authorities under the genus Glaucilla Bergh, 1860. Presently, both species are listed under Glaucus Poli, 1795.

Xenopeltis unicolor Boie, 1827 predation upon Sphenomorphus sp.

Bruno H. Martins & Gonçalo M. Rosa*
*E-mail: goncalo.m.rosa@gmail.com

Xenopeltis is a genus of non-venomous snakes characterized by its iridescent, highly polished scales which give to the species the common name “sunbeam snake”. Currently, two species are recognized. Xenopeltis unicolor Boie, 1827 is found in Southeast Asia and some regions of Indonesia occupying a variety of habitats from primary to secondary forests, agricultural and settled areas from elevations up to 1402 m. Being nocturnal and subfossorial, this species inhabits burrows excavated by small mammals and crevices within limestones, spending large amounts of time underground on the leaf litter. Pre-maxillary teeth are found in the aglyphous dentition of X. unicolor enabling a varied diet that consists primarily of frogs, lizards (particularly skinks), small mammals (such as rodents), birds and even other snakes.
