About These Birds
Montezuma Quail
약 185g의 Odontophoridae 과의 소형 통통한 신세계 메추라기로 수컷은 어릿광대 무늬의 흑백 얼굴을 가진다. 애리조나·텍사스에서 온두라스까지 산지의 소나무-참나무·초원 서식지에 서식. 강한 굽은 발톱으로 구근과 괴경을 파며 채이며 먹는다. 최소 관심; 은밀하여 좀처럼 보기 어려우며 토착 묶음풀 과도 방목으로 개체수 감소 중.
Nahan's Partridge
A small partridge (~280 g) of family Odontophoridae, dark reddish-brown with black barring. Endemic to lowland primary rainforest in Uganda and the Democratic Republic of Congo. Highly terrestrial, foraging on the forest floor for seeds, berries, and invertebrates. Vulnerable; requires intact primary forest and is threatened by widespread logging and agricultural conversion in Central Africa.
