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.
<em>Comatricha filamentosa</em> is a myxomycete belonging to the genus <em>Comatricha</em>, order Stemonitidales, class Myxomycetes. The species is distinguished within the genus by features of its filamentous capillitial threads and spore morphology, which are used as diagnostic characters in taxonomic identification. It has been recorded from Europe, where it inhabits decaying wood and plant litter in forest and woodland habitats. Like other plasmodial slime molds, <em>C. filamentosa</em> passes through a motile plasmodial feeding stage, consuming bacteria, fungi, and decomposing organic matter, before forming fruiting bodies under conditions of environmental stress or nutritional depletion. The resulting sporangia release spores suited for wind dispersal. This species plays a role in nutrient cycling within woodland ecosystems. No quantitative biological metrics are available, and it has not been assessed by the IUCN.
