Breeding and Reproduction of the Blue-Eared Kingfisher
Breeding and reproduction in the Blue-Eared Kingfisher (Alcedo minting) offer a fascinating glimpse into the life cycle of these vibrant birds.
Here’s an overview of their breeding behavior:
Breeding Season
The breeding season for Blue-Eared Kingfishers typically occurs from late March to July. During this time, males and females engage in courtship displays and nest-building activities.
Nest Construction
Both males and females participate in excavating their nest caves, which are typically dug into riverbanks or sometimes in rotten trees. These cozy burrows can extend up to one meter deep, protecting the eggs and chicks.
Egg Laying
A female Blue-Eared Kingfisher will lay between 4-7 eggs per clutch. The eggs are pearly white ovals laid directly on the bare ground of the nest burrow.
Incubation
Both parents take turns incubating the eggs for approximately three weeks until they hatch. During this period, the parents diligently keep the eggs warm and protected.
Chick Rearing
After hatching, the chicks are initially helpless and rely entirely on their parents for food and warmth. The male provides food for the female and chicks, frequently delivering fresh catches to the nest.
