The dorsal surface was characteristically olive brown to bright green in colour and the ventral surface was whitish. Black spots were distributed between nostril and between eyes. The length of snout-vent, head, snout were found to be 43.25 mm, 14.50 mm and 7.5 mm, respectively. Some information of its natural history is also included in the paper.

Garden, Bangladesh (NBGB), by direct field observation from September 2011 to February 2012. A
total of 65 species of birds belonging to 11 orders, 28 families and 53 genera were observed. Majority
of the birds were resident (56 spp.) and very few were migratory (9 spp.) in nature. Among the
identified birds, 34 species were passerine of which 29 species were resident and 31 species were
non-passerine of which 30 species were resident. Identified birds were categorized into five groups
(rare, few, fairly common, common and very common) based on their abundances where, more than
half of the birds were found to be very common.

Consequent to the land use and land cover change, habitat loss, fragmentation, and deterioration of the corridor status are the prime threats for the species. The current study aimed to delineate the routes and migratory corridors of elephants in the Indo-Bangla forest along the Patharia Hills Reserve Forest and characterizing existing threats on the corridor for long-term conservation of the elephants using field survey and geospatial techniques. The study identified and mapped the elephant corridor for the first time in the area and named it the "Juri-Patharia-Tilbhum elephant corridor." Land use and land cover changes in the corridor were markedly observed for over 4 decades (between 1972 and 2018). Forest-covered areas in the corridor were 32.06% in 1972, which has been reduced to only 2.98% in 2018, whereas human development types have all increased, grasslands by 127.18%, plantations by 146.56%, agriculture by 279.63%, and settlements by 147.17% between 1972 and 2018. The study concluded that the corridor area is at risk because of the lack of sustainable development in the area, which deliberately undermines conservation. Human settlement, road construction, and electrification in and around habitats and the corridor are vital threats faced by elephants in the Patharia Hills Reserve Forest. Conservation of habitat and corridor through both adoption of legal measures and community participation might be a better proposition for their long-term conservation in the habitat. The study appeals to the government to take conservation initiative in the area and suggest legal protection of the corridor and provide subsidies to the local private landowner to restrict the land-use change on the corridor.

Consequently, wild animals come out from the fragmented habitats and compete with the human for resources. In order to reduce this conflict, sustainable habitat management balancing the socioeconomic needs of the people is of the utmost importance. The present study is an effort to assess the elephant’s habitat suitability in the trans-boundary forested areas of India and Bangladesh, Patharia Hills Reserve Forest. This is an important study considering the increased human–elephant conflict in the area, and also the area is home to many IUCN’s red-listed animals including Chinese pangolin, spectacled monkey, capped langur. Field surveys were conducted to collect the elephant distribution data and identify potential anthropogenic disturbances. Remote sensing and geographic information system along with analytical hierarchy process were used in the methods for modeling habitat suitability to identify habitat parameters and preparation of suitability maps. Vegetation status (32.50%), settlements (23.30%), elevation (17.20%) and water sources (12.70%) were found to be the most weightage parameters for the movement of the elephant. The study on elephant habitat suitability mapping in the trans-boundary forest revealed that 6.88% area of the habitat is highly disturbed, 36.07% area is somehow disturbed, 35.38% area is moderately suitable and only 21.67% area is most suitable for the Asiatic elephants. Identification of suitable areas and potential factors disturbing the habitats is important for conserving and management of wildlife for particular species and in particular sociophysical conditions. Sustainable management strategies can be fixed based on the findings for the long-term conservation of elephants and other wildlife of the area.

A pair was observed mating near a small bush on an island in the Buriganga River at 11h10 on 14 January 2014. Nine successive copulations were separated by about 20 to 50 seconds. Masked Palm Civet Paguma larvata is believed to be rare in Bangladesh and its behaviour is very poorly known. A pair up a tree in Satchari National Park at 07h43 on 25 April 2014 was observed copulating (two bouts) and its post mating behaviour documented.
