The house crows Corvus splendens Vieillot are accustomed to construct nest in suitable trees belonging to certain species. In the present study an attempt was made to draw the affinity of crows with the nest-tree species occurring in and around Kolkata (22°34′N, 88°24′E), West Bengal, India. Accordingly, survey was conducted in different road side trees during the period of eight consecutive breeding seasons from 2006 to 2013. Of the recorded 46 nest-tree species belonging to 27 families, irrespective of Ivlev’s and Jacobs preference indices, 13 were of ‘exclusive selection’, 2 were of ‘no active selection’ and 16 were of ‘complete avoidance selection’ by C. splendens for nesting. The status of the remaining 15 nest-tree species were either avoiding or no active selection in nature. Out of 13 exclusive/complete selection nest-tree species 8 species harboured 85.65 % of the total 1,171 nests recorded out of 3,083 nests in course of studies. Apart from canopy configuration, leaf phenology and food resource mobilization these nest-tree species had a number of spots, amongst the ramifications, presenting a platform because of agglomeration of 2–3, 4–5 or more than 5 suitable branches. As such kinds of spots were the sites for construction of nest by C. splendens; it is imperative that the said factor determines the affinity of house crows with the nest-tree species.
