About These Birds
Bearded Wood-partridge
약 405g의 Odontophoridae 과 중형 신세계 메추라기로 수염처럼 보이는 뚜렷한 얼굴 줄무늬를 가진다. 멕시코 동부 시에라 마드레 오리엔탈의 제한된 지역 운무림 고유종. 씨앗과 무척추동물을 땅에서 채이며 먹는다. 취약종; 농업 확장으로 인한 서식지 손실로 멕시코 고지 삼림이 크게 파편화됨.
Buffy-crowned Wood-partridge
약 370g의 Odontophoridae 과 중형 신세계 메추라기로 황갈색-흰 눈썹선과 황갈색-갈색 깃털을 가진다. 멕시코에서 중앙아메리카를 거쳐 파나마까지 산지 운무림·습윤 고지림에 서식. 씨앗·장과류·무척추동물을 땅에서 채이며 먹는다. 최소 관심; 밀생 삼림과 은밀한 행동으로 자주 들리지만 좀처럼 보기 어렵다.
