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.

Rufous-tailed Hummingbird

붉은꼬리벌새(Amazilia tzacatl)는 중앙아메리카와 남아메리카 북서부에서 가장 흔한 벌새 중 하나로, 녹색 상체와 선명한 적갈색 꼬리가 특징인 중형 종이다. 멕시코에서 에콰도르, 트리니다드까지 해발 0~2,100m의 숲 가장자리, 정원, 농장, 2차 성장림 등 다양한 서식지에서 발견된다. 먹이 식물과 급이대에서 영역을 적극적으로 방어하며, 서식 범위 전역의 정원에서 자주 목격된다. IUCN 관심필요종이다.
