Purple-winged Ground Dove Paraclaravis geoffroyi

Extremely rare ground dove, possibly extinct. Males are dark gray-blue with broad dark bands on the wings; in flight, exhibit white outer tail feathers. Females are similar but brown. Apparently is (or was) highly dependent on humid forests with flowering bamboo. The song is undescribed, but was reportedly similar to that of Blue Ground Dove. Also separated from Blue Ground Dove by the black outer tail feathers and females with spotted wings.
