The Dollarbird, Eurystomus orientalis also known as the Dollar Roller is a bird of the roller family, so named because of the distinctive blue dollar shaped spots on its wings, as seen here.
Here an adult Dollarbird is bringing back an insect as food to feed its young chick, which is residing in a hole in the trunk (not visible in the pic). Interestingly, it made this particular nest in the hollowed out trunk which was part of a man-made structure off the coastline. Smart move as it is almost inaccessible to most predators save for raptors. The chick fledged about a week after this photo was taken.
