When seen rapidly and erratically flying overhead when catching their insect prey, the true beauty of these small birds cannot be appreciated. When observed closely on a perch, the iridescent blue-green upper parts and pure white underparts are striking. Image made with Canon 7D mark2 and Canon 500mm F4 IS L lens plus 1.4X teleconverter. Exposure was 1/400 second AT F 8.0, 0 EV, ISO 500.
