The Bohemian waxwing is a starling-sized songbird, 19 to 23cm long, with buff-grey plumage, a pointed crest, a black face mask, red waxy tips on the wings and a yellow tail band. It lives in mature coniferous forest across northern Eurasia and North America, and outside the breeding season visits towns, gardens and roadsides, feeding in large flocks that can be very tame (Wikipedia, general species account).
It eats mostly fruit such as rowan berries in winter and insects in summer. The female incubates three to seven eggs in a cup nest in a tree for 13 to 14 days. It winters from eastern Britain across Europe to Japan and in some years irrupts far south of its usual range. The source does not mention Nepal or South Asia, so its status on the Nepal list should be checked (Wikipedia, general species account).
