Nest fidelity of purple sunbird (Cinnyris asiaticus) on communal webs of a spider
P. Selvaraj* & S. Kamalanathan *Corresponding author. E-mail: prachemist@gmail.com
Nest predation is a major cause of avian breeding failure and parent birds adopt various anti-nest predation strategies to increase the survival rate of offspring. Purple sunbird uses snake moults as nest-building material, which could be a tactic to avoid predation of eggs and hatchlings inside the nest.

Although several checklists exist of herpetofauna in Bhutan, these are based on citizen science data or report the diversity of individual regions and published records are lacking for many areas. Like the country as a whole, there is no formal checklist or report for Sarpang District despite the fact that most of this district is encompassed within three protected areas namely Royal Manas National Park, Jigme Singye Wangchuck National Park, and Phibsoo Wildlife Sanctuary.
Fishes of the cyprinid genus Pethia are diagnosed from other cyprinid genera by a suite of characters that includes small adult size (usually less than 50 mm standard length (SL), exceptionally up to 80 mm SL), absence of rostral barbels, absence or rudimentary maxillary barbels, last unbranched dorsal-fin ray stiff and serrated, 3 to 4 unbranched and 8 branched dorsal-fin rays, 3 unbranched and 5 branched anal-fin rays, lateral line complete, interrupted or incomplete with 19–24 scales in lateral series, and a unique color pattern consisting of a humeral spot, a black blotch on the caudal peduncle, and in some species, black blotches, spots or bars on the body. Pethia are distributed throughout South and Southeast Asia, from Sri Lanka and peninsular India in the west, to Myanmar in the east.

Migrations of butterflies are common phenomena, yet they are one of the greatest natural events on earth. The migration of monarch butterflies, Danaus plexippus (L.) is a spectacular event that has received great attention in northern America. They travel 1,200–2,800 miles from the northeast United States and southeast Canada to the mountain forests of central Mexico, where they find suitable climatic conditions to hibernate from the beginning of November to mid-March. This swarming occurs primarily across North American land mass, so does not cross the sea. Although migration appears to be widespread among butterflies, its prevalence, and migration behaviours, are poorly understood.
Abstract We add seventeen new provincial records for fifteen snake species of Laos with precise localities and elevations. These new records result from 45 independent surveys conducted at different times between the years 2016 and 2021 in all Laotian provinces except Attapu. In all field trips, we took a series of photographs that allowed us to prepare high-resolution photographic plates that then allowed us to identify all individuals down to species level. No specimen was killed and preserved. Here we provide the list of all new localities of snakes photographed during our surveys. We discuss potential systematic problems and the biogeographic implications of these new provincial records.
