About Eurystomus glaucurus (P.L.S.Müller, 1776)
This bird species, commonly called the broad-billed roller, has the scientific name Eurystomus glaucurus (P.L.S.Müller, 1776). The adult broad-billed roller measures 29–30 cm in total length. It has warm-toned back and head, with lilac-colored foreneck and breast. Most of the rest of its plumage is primarily brown, and its characteristic broad bill is bright yellow. Males and females have similar appearance. Juveniles are a drabber version of adults, with a pale breast. In its strong, direct flight, the broad-billed roller is very striking; the brilliant blue color of its wings and tail contrasts sharply with its brown back. Its call is a snarling k-k-k-k-k-r-r-r-r-r sound. This species lives in open woodland that has some tall trees, and it prefers habitats located close to water. Broad-billed rollers often perch prominently on trees, posts, or overhead wires, similar to giant shrikes. They remain inactive for most of the day, except when chasing intruders. In the late afternoon, they hunt to feed on swarming ants and termites, and sometimes they gather in groups of 100 or more individuals while feeding. They drink in the same manner as swallows, dipping their bills into water while flying. They nest in an unlined hole inside a tree cavity, and they lay a clutch of 2 to 3 eggs.
