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.

Cinnabar Boobook

The cinnabar boobook (Ninox ios) is a small owl in the family Strigidae, endemic to Sulawesi in Indonesia. It inhabits primary and mature secondary forest at low to mid elevations on the island, typically in humid lowland to foothill forest. Like other boobook owls, it is nocturnal, roosting in dense foliage during the day and hunting small vertebrates and invertebrates by night. The cinnabar boobook has rich rufous-brown upperparts and a distinctive reddish coloration that gives the species its evocative common name. The species is classified as Least Concern by the IUCN, with populations considered stable within its Sulawesi forest range. Sulawesi is a biogeographically remarkable island at the intersection of the Asian and Australian faunal zones, hosting a high proportion of endemic species. The island's forests face ongoing pressure from logging, mining, and agricultural encroachment, but the cinnabar boobook's adaptability to secondary forest provides some resilience. The species is entirely restricted to Sulawesi and does not occur in Europe; any database records listing Norway are data entry errors. The genus Ninox comprises the boobook owls of Australasia and Southeast Asia, with numerous island endemic species across Indonesia, the Philippines, and the Pacific islands.
