加羅林夜鷹

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.

大苇莺

大苇莺（Acrocephalus arundinaceus）在IUCN红色名录中被列为极度濒危物种（CR）。由于种群数量严重下降和栖息地丧失，在野外面临极高的灭绝风险。
