It is relatvely robust to habitat loss, evident Bengal in India, but hardly any behavioural documentaton is enlisted tll date. The nestng behaviour of the subject bird encompassing its from its appearance in forest edges and urban green parental behaviours was studied on a wetland stretch of Ishapore, spaces. Combined with its extraordinarily widespread southern Gangetc Bengal. The present study mainly deals with the nestng behaviour, incubaton actvites, hatching, and parental care distributon, it is not locally nor globally threatened and is to fedging of a wild pair. The behavioural changes at par with the currently rated as Least Concern (LC) by the Internatonal changing weather conditons and the neighbouring species too were Union for the Conservaton of Nature (IUCN 2019). studied. Studies on the courtship, nestng, and feeding behaviour Keywords: Bart Beel, behaviour, brooding, courtng, fedging, are available sparsely (Mizuta & Yamagishi 1998; Gokula hatching, incubaton, Ishapore, parental care, Passeriformes. & Vijayan 2003). Many sightngs of this passerine variety were noted throughout the state but no informaton on its biology, ecology, or behaviour is available from The Asian Paradise Flycatcher Terpsiphone paradisi the lower Gangetc plain despite a good number of is a medium-sized passerine bird that inhabits forests photographic records. The present work aimed to study and well-wooded habitats in diferent parts of Asia. It the behavioural aspects of the Asian Paradise Flycatcher is a widespread resident in the Indian subcontnent in relaton with courtship, nestng, and parental care and migrates seasonally. In West Bengal State in India, from the southern part of West Bengal. however, the species is a summer visitor (Grimmet et al. 2011; Rasmussen & Anderton 2012). Asian Paradise Study site Flycatcher exhibits sexual dimorphism. Breeding pairs The study area was located near a wetland named are monogamous.

A safe hideout disturbances. The forest covered a long range of mostly at a distant bush resulted in locatng/recording the bamboo vegetaton, with mango and guava trees lining repeated visits of the couple to the nest, with alternate a narrow mud path. Agricultural felds, ponds, and the (mostly, the female was engaged in the incubaton wetland area are fooded during the monsoon. process) intervals of sitng (assumed to be incubatng the eggs), which confrmed the presence of eggs in the Behaviour study nest, though the number could not be confrmed then. Observatons were carried out from 05 June to 19 July Being socially monogamous, both male and female took 2017 on a single nest. The observatons were made from part in nest-building, incubaton, brooding, and feeding a safe hide-out with proper camoufaged clothing and of the young. A sudden heavy rain on the 11th day of ambience. A considerable distance from the nest was the observaton period showed the fact that both the maintained to avoid disturbances during observaton.

Tree and nest the nest was spoted confrmed the presence of nests of heights and distances were measured by TruPulse 300 a few other species, namely Lineated Barbet Megalaima laser range fnder. The girth of the tree at chest height lineate, Coppersmith Barbet M. haemacephala, and was measured using a measuring tape. The birds were Black-hooded Oriole Oriolus xanthornus. On the 27th day not marked, the size of the clutch was not measured, of the observaton period, the peeping of a chick was the and nest was not touched or brought down for observed inside the nest. The act of feeding the juvenile measurement purposes even afer being deserted by by the parents in alteraton, mostly again by the female, birds as chances remained for another couple to use the facilitated the documentaton. Right afer six days (i.e., same. on the 33rd day of the observaton period) from the frst observaton of the chick, two more chicks were observed Results and Discussion inside. Since the nest was not hampered or no atempt The nest was built at a height of 4.15m in the branch was made to have an eye-level view of the nestng, the of a Mango Tree Mangifera indica (height 6.35m, girth exact clutch size could not be determined; however, the 179cm). The nest was chiefy made with twigs and number of chicks (here, three in number) could possibly spider webs on the end of a short branch. The nest give an overview of the same. The feeding behaviour was located on the third day of the observaton period was observed prior to fedging, even when the chicks (Table 1). Initally, due to the height at which the nest were capable of coming out of the nest to the nearby was located and the tendency of the observers to not twigs/branches. Feeding mostly comprised of ants, disturb the ambience and the conditon of the nest, small insects, and damselfies torn into parts. it was not approached directly.
