Chong'an Moustache Toad

The Chongan Moustache Toad (Leptobrachium liui) is a robust, terrestrial frog in the family Megophryidae, native to the subtropical mountainous forests of south-central China, particularly the western Fujian, Jiangxi, and Sichuan provinces. Megophryid frogs are a diverse Asian family adapted to cool, humid forest streams, and many species display remarkable breeding biology. The moustache toad is best known for the extraordinary breeding biology of its congener Leptobrachium boringii — males of that species grow sharp, keratinous spines on the upper lip during the breeding season, used in aggressive fights over calling sites — and similar adaptations may occur in L. liui. Adults are cryptically coloured in browns and greys, resembling leaf litter. They breed in fast-flowing mountain streams, where females deposit large eggs in sheltered sites and the resulting robust, bottom-grazing tadpoles are well adapted to current environments. The IUCN classifies Leptobrachium liui as Least Concern with a broad enough range in montane forest habitats of central China to sustain viable populations. Threats include forest degradation, water pollution from agricultural runoff, and collection for the food and traditional medicine trades, which affect many frog species in China and Southeast Asia.

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.
