Giant Kingfisher.

The Giant Kingfisher is the largest Kingfisher and it certainly lives up to its name being an incredible 18 inches in length. It frequents wooded rivers, lagoons, lakes and mangrove plantations. It perches quietly, often out of sight, watching for crabs and fish. The male birds have a chestnut breast and a white belly with black barring. This bird looks like a juvenile because the barring on the belly is not showing much yet.
The female’s plumage is the reverse of this.
In flight they are so large they can be confused with some small Herons.
We found this bird perched over a water filled ditch as it tried to regulate the heat by ventilating on a blisteringly hot day.
