Abstract
The Asian paradise flycatcher Terpsiphone paradise is a graceful looking medium sized
bird widely found in the forest area of different parts of Asia including
India. These birds exhibit distinct sexual dimorphism with males being present
in two or more morphs. The present work is aimed to study the detailed
nesting behaviour and parental care of Asian paradise flycatcher from north 24
parganas district of West Bengal. Observations were carried out during May to
July of 2021 and 2022. A total of 12 nests were observed during our study. Our
observation revealed that these birds made small cup shaped nest. The female
usually lays 3-4 egg and both male and female alternately incubate the eggs
till they hatch. Both the parents take part in feeding and other parental
cares. We also observed a specific correlation between the development of
chicks and time of bathing of the parents. We report here, an ethogram based on
the observed behaviour of these birds. In short our study revealed some
insights into the nest building and parental care of paradise flycatcher.

Introduction
Terpsiphone paradise commonly known as Asian or Indian Paradise flycatcher is a beautiful looking bird found in different parts of Asia. In West Bengal they visit in summer (Grimmett et al., 2011, Rasmussen & Andertor 2012). Reports suggests that there is a nonmigratory variety of Asian paradise flycatcher belonging to subspecies affinis. The migratory subspecies is incei (Das N. & Adhikari S. 2019). The two subspecies differ in their breeding season. The size of the adult bird is between 18 to 22cm. Their heads are glossy black with a black crown and crest, black bill and black eye. They exhibit prominent sexual dimorphism. The females are rufous on the back side with grayish throat and grayish to white on the ventral side. Males occurs mainly in two morphs, one with rufous or glossy chestnut upper plumage and another with white plumage. The young males look almost like the females with rufous colour and short tail but have a black throat and blue ringed eyes.
The Asian paradise flycatcher has 12 tail feathers. Out of the 12 feathers two central feathers of adult males are elongated greatly and form streamers (Mizuta T. and Yamagishi S. 1998). The length of the tail of adult male can be 20-24cm, with the central feathers growing upto 30cm long streamers. The males acquire the long central feather in 2nd or 3rd year. Asian paradise flycatcher is socially monogamous animal and belongs to schedule IV according to wildlife protection act 1972 and is classified as least concerned by IUCN (IUCN 2019)
Studies on the nesting
behaviour and parental care of Asian paradise flycatcher are sparsely available
(Gokula V & Vijayan L 2003, Das N & Adhikari S 2019). The present work
is aimed to study the detailed nest building behaviour and parental care of
Asian paradise flycatcher.
