The Common Kingfisher (Alcido atthis), also known as Eurasian
Kingfisher or River Kingfisher, is about 16 cm long small bird with green-blue
upper parts, azure blue back and rump, amber underside, long black beak, white
throat, small orange legs, and short stubby tail. It is a resident species
across Eurasia and North Africa.
They live on
small fish and other aquatic insects which they catch from under water surface by
flash diving from their perch. They must
eat about 60 per cent of their body weight each day to survive. So, these birds
prefer shallow but clear water habitats where they can easily see their prey
under water. This is why the Kingfisher density is an important indicator of
the health of the freshwater bodies. Higher density indicates better quality
water.
