Common kingfisher,カワセミ

This is second installment of a six-part series of this feature article.
 Adult: Breeding season :Mmatchmaking and digging a hole for nesting
 Needless to say, the most important thing for animals to live is the acquisition of food.
In the case of kingfishers, according to ADW, they eat small fish, crustaceans and aquatic insects equivalent to 60% of their weight per day. It has a very strong territorial because it must secure a sufficient feeding ground for that. The range is said to be 1 km to 3 km.
Here, in February for breeding, males chase a female every day to determine the breeding partner. And the male starts digging the hole for nesting and the female also cooperates and does. From this time onwards, there is frequent courtship feeding that shows affection to the female until mating.
Moreover, the height of the nest hole from the water surface was 2m,and the nest burrow length I measured in the local was about 80 cm. The end of the burrow was wide sideways.
