Abundant in Kenya but common throughout most of the African acacia range, these birds are swift, territorial and vocal. They perch on treetops and swoop down to scoop their prey, mostly lizards and small vertebrates. They nest in trees or termite rounds whereby they lay their eggs. Both sexes incubate the eggs. Their body is pale greenish blue; however, as their name suggests, the base of their throat and breast and their rump are pale violet.
