A breeding record of the brown hawk owl (Ninox scutulata) in Assam, India
S.P. Ranade* *E-mail: s.ranade@bnhs.org
The brown hawk owl, Ninox scutulata (Raffles, 1822) is a common, medium sized bird of prey on the Indian subcontinent and listed as of least concern. Its distribution range extends up to eastern Siberia, Japan, the Andmans, the Malay Peninsula, the Great and Lesser Sundas, Wallacea, Taiwan, the Philippines and Australia. There are 11 well documented subspecies across this wide distribution. A pair of brown hawk owls was observed nesting on a Dillenia indica tree (Family Dilleniaceae), in Guwahati, Kamrup District, Assam, India. The nest was in a cavity at a height of about 4 m. The tree was about 14 m tall and the main trunk was about 7 m in girth. It had a dense canopy with its large elliptical leaves.
The crowned river turtle, Hardella thurjii (Gray, 1831) is widely distributed from Pakistan to Bangladesh, and possibly in western Myanmar. It prefers the middle and lower reaches of the northern river systems on the Indian subcontinent, comprising the Indus, Ganga, Brahmaputra, and their tributaries. The species is classified as Endangered, but nationally remains a poorly protected species under the Indian Wildlife Protection Act. This communication presents the first photographic evidence of the crowned river turtle, from Gujarat State, India. It was previously reported from North Gujarat two decades ago, but without any evidence.

Chromatic leucism in the flap shell turtle, Lissemys punctata from Bangladesh

The spotted flap shell turtle, Lissemys punctata (Bonnaterre, 1789) has a distribution in Bangladesh, India, Myanmar, Nepal and Pakistan. In Bangladesh, this species is widely distributed throughout the freshwater wetlands and the low-lying floodplains, coastal islands, and hill districts. This species is listed in CITES (Appendix II) and protected by Bangladesh Wildlife Conservation & Security Act 2012 (Schedule II), where commercial trade is strictly prohibited. Lissemys punctata has an oval and domed carapace with olive-green colour spotted by dark yellow blotches. The head is also olive green often with yellow blotches, whereas the plastron is whitish or pale yellow. The colour of this species may vary depending on its habitat and defence strategy. Colour aberration in animals may occur due to a lack of melanin. Golden yellow colour aberration (chromatic leucism) is rare in animals, especially in turtles. This might be because of the absence of melanin in the outer dermis. The presence of high xanthophores and yellow pteridine pigments in the skin are also responsible for the golden yellow colour aberration.
Nearly one in every five species of reptiles in the world is threatened with extinction and thus is conservation dependent. In order to develop effective and targeted species conservation strategies, detailed information on their distribution, systematics and ecology are necessary. Information such as the natural history and in-situ reproductive behaviors would be crucial for highly threatened species that require ex-situ conservation measures. Agamid lizards are a major component of the global reptile diversity and a significant number are threatened due to habitat loss and other threats such as smuggling.

Ophiophagy by banded krait (Bungarus fasciatus) exposed by a road kill
L. Biakzuala, Malsawmtluanga & H.T. Lalremsanga* *E-mail: htlrsa@yahoo.co.in
Bungarus fasciatus (Schneider, 1801) is a nocturnal, large bodied krait species, widely distributed throughout South and Southeast Asia. It is found at a variety of habitats with relatively large home ranges. The ophiophagous diet of this venomous snake comprises a broad spectrum of prey items, even including its congener B. caeruleus. It also preys on skinks, fish, frogs, and eggs of snakes. On 16 June 2021, at 2105 h, a fresh road-kill of an adult male B. fasciatus (total length 1.46 m) was observed on a newly constructed tarmac road (width of road ~6 m) at New Khawlek (23°19'16.00"N, 92°38'36.95"E; alt. 715 m a.s.l.), Lunglei District, Mizoram, India. It seems the krait remained vulnerably exposed on the motorway while consuming a redtail pit-viper, Trimeresurus erythrurus (Cantor, 1839) (total length 48.8 cm), and was fatally run over while busy swallowing more than half of the length of its prey, most probably a few minutes prior to our arrival at the site.
