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.

Common Eyelash

The Common Eyelash (<em>Scutellinia scutellata</em>) is a small cup fungus belonging to the genus Scutellinia within the family Pyronemataceae. It is recognised by its distinctive scarlet to bright red disc-shaped fruiting body, typically measuring just a few millimetres across, and fringed with dark brown hair-like structures resembling eyelashes, from which its common name derives. This species is native to Asia and Europe and North America, and typically inhabits decomposing wood, moist soil, and other organic substrates in humid environments. Its geographic range is wide, with confirmed records across Asia including Taiwan, Europe including Belgium, Denmark, Norway, and Portugal, North America including the United States, and South America including Brazil. <em>Scutellinia scutellata</em> is assessed as Least Concern on the IUCN Red List, reflecting its broad distribution and apparent abundance. Biological traits such as lifespan, size, and specific dietary habits remain poorly documented in the scientific literature, though as a saprotrophic fungus it typically obtains nutrients by decomposing dead organic matter.
