コヨタカ Setopagis parvula

Small nightjar; streaked gray, brown, and rufous above with a white throat and buff collar. Males have a white wing band near the tip and pale central tail feathers, absent in females. Resembles Spot-tailed Nightjar, which has a well-marked buffy neck and lacks the white throat and white wing patches. Found in variety of open habitats including pastures, bushy areas, and forest edges. The song is an odd, memorable, descending “drui-dro-dro-dro-dro-dro.”
