A small, dainty bee-eater of arid, open terrain with scattered trees, including semideserts, palm groves, and gardens. Mainly green with a slender black face mask, throat band, and a stunning electric-blue face and throat. Juveniles are duller than adults and lack the short tail spike. In flight, note the rusty underwing with a black trailing edge. Flies gracefully as it catches insects and other prey. Calls are a series of gentle liquid trills or more staccato notes.
