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.

Coastal stingaree

Coastal stingaree (Urolophus orarius) is a small batoid ray in the family Urolophidae, endemic to shallow coastal waters of southern Australia, particularly along the coasts of South Australia, Victoria, and Tasmania. Like other stingarees, it has a rounded disc, a short tail armed with one or two venomous spines, and lacks a distinct rostrum. It inhabits sandy and muddy nearshore substrates in depths typically less than 30 metres, where it forages for polychaete worms, crustaceans, and small molluscs buried in the seabed. Females are ovoviviparous, giving birth to small litters of live young following internal development. Coastal stingaree is assessed as Endangered by the IUCN, driven by its restricted range, slow reproductive rate, and significant bycatch in inshore commercial and recreational fisheries operating across southern Australian coastal waters. Bottom trawling, prawn trawling, and gillnetting are identified as major threats. The species receives limited targeted conservation attention and is not currently the subject of specific fisheries management measures. Its small home range and coastal distribution make it especially vulnerable to localised fishery impacts.
