Nests of Collared Kingfisher
Collared Kingfisher is most commonly found in coastal areas, particularly in mangrove swamps. It also inhabits farmland, open woodland, grassland and gardens. In some parts of its range, especially on islands, it can be seen further inland, ranging into forest or into mountain areas. Birds often perch conspicuously on wires, rocks or bare branches.
Feedings of Collared Kingfisher
The small crabs are the favoured food in coastal regions but a wide variety of other animals are eaten including insects, worms, snails, shrimps, frogs, lizards, small fish and sometimes other small birds as well. The bird perches almost motionless for long periods waiting for prey. When it spots something it glides down to catch it and then flies back to the perch where larger items are pounded against the branch to subdue them. Any indigestible remains are regurgitated as pellets
Nestling of Collared Kingfisher
The nest of Collared Kingfisher is a hole, either a natural tree hole or a burrow excavated by the birds themselves in a rotten tree, termite mound or earth bank. They will also occupy old woodpecker holes. Two to seven rounded whitish eggs are laid directly on the floor of the burrow with no nest material used. Both parents take part in incubating the eggs and feeding the chicks. The young birds leave the nest about 44 days after hatching. Two broods are often raised in a year.
