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.

Colombian Soft-furred Spiny-rat

<em>Diplomys caniceps</em>, the Colombian soft-furred spiny rat, is a rodent in the family Echimyidae found in Colombia. The genus <em>Diplomys</em> is characterised by a pelage that, despite the common name, is relatively soft compared to other spiny rats, with spine-like guard hairs interspersed among the fur. This species is assessed as Data Deficient by the IUCN, indicating that available information is insufficient to determine its conservation status reliably. Data Deficient assessments typically arise when a species occupies remote or poorly surveyed habitats, or when taxonomic uncertainties complicate population estimates. <em>Diplomys caniceps</em> is believed to inhabit tropical lowland and montane forests of Colombia, where it likely feeds on plant material including seeds, fruits, and fibrous vegetation. As a medium-sized terrestrial rodent, it probably serves as prey for a range of forest predators. The lack of ecological and distributional data underscores the need for targeted field surveys. Biological traits of this species remain poorly documented in the scientific literature.
