Chuck-will's-widow

The Chuck-will's-widow (Antrostomus carolinensis) is the largest nightjar in North America, named for its distinctive far-carrying call — a resonant four-syllable whistle repeated persistently on warm nights. It breeds across the southeastern United States, from the Atlantic coastal plain through the Gulf states and up the Mississippi Valley to southern Indiana and Kansas. The species migrates southward in autumn to winter quarters in the Caribbean, Central America, and northern South America. Like all nightjars, it is a crepuscular and nocturnal insectivore, capturing large moths, beetles, and other flying insects in flight using its enormous, bristle-fringed gape. By day, the Chuck-will's-widow roosts on the ground or along horizontal branches, relying on cryptic mottled plumage for concealment. It nests directly on the leaf litter of open woodland and scrub, typically in pine-oak forests, dry forests, and woodland edges. The IUCN classifies this species as Least Concern, though Breeding Bird Survey data suggest moderate long-term population declines linked to forest fragmentation and light pollution that disrupts insect prey availability. Conservation of large-scale woodland tracts in the southeastern United States benefits this species and its associated nightjar community.

Collared Inca

콜롬비아에서 볼리비아에 이르는 안데스 산악림에 서식하는 중대형 벌새인 목테두리잉카벌새는 넓은 흰색 가슴 띠와 비행 중 잘 보이는 뚜렷한 흰색 꼬리 반점을 가진 눈에 띄는 흑백 깃털을 가지고 있습니다. 해발 1,700-3,200미터의 삼림 및 삼림 가장자리에 서식하며 다양한 꽃식물에서 먹이를 찾고 안데스의 대형 꽃 관목과 나무의 중요한 수분 매개자입니다. 대조적인 흰 꼬리 반점은 제자리 비행 중 두드러지게 번쩍이며 종 식별에 도움을 줍니다.
