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 swift

<em>Korscheltellus lupulina</em>, the common swift moth or ghost swift, is a moth in the family Hepialidae, order Lepidoptera. It is recorded from Belgium, Denmark, Norway, and Sweden, with a broader distribution across Europe and temperate Asia. The species typically inhabits grasslands, meadows, garden lawns, and field margins where its larval host plants grow. Adult ghost swifts are notable for their spectacular lek-like swarming behavior at dusk, in which males hover in groups to attract females, appearing to hover like ghosts over vegetation. Larvae of <em>Korscheltellus lupulina</em> feed underground on the roots of a variety of herbaceous plants and grasses, including hop (Humulus lupulus), which gives the species its specific name. Adults do not feed, having vestigial mouthparts, and live only long enough to reproduce. Biological traits including precise larval duration, adult size measurements, and detailed host plant specificity remain poorly documented at the species level. The species is assessed as Least Concern by the IUCN, with stable populations across its European range and no significant conservation threats identified.
