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.

ciliate oak scale

Ciliate oak scale (Eulecanium ciliatum) is a soft scale insect in the family Coccidae, found in Europe. Like other soft scales, the adult female forms a protective waxy or leathery scale cover under which she lays eggs and overwinters. Eulecanium ciliatum is associated with oak (Quercus) as its primary host, though it may also occur on other deciduous trees. The species feeds by piercing plant tissue and extracting phloem sap, and heavy infestations can weaken host branches; however, it is generally not considered a major economic pest. The name ciliatum refers to fringed or ciliate margins of the scale cover or body. Scale insects of the family Coccidae are widespread in temperate and subtropical regions, and many European species are incompletely documented in terms of distribution and population status. Eulecanium ciliatum has not been formally assessed by the IUCN. Natural enemies including parasitoid wasps, predatory beetles, and lacewings help regulate scale insect populations in forest ecosystems. The taxonomy of European Eulecanium has been subject to revision, and several historical records may require reassessment given updated species concepts. Oak forests across Europe support a rich community of specialist scale insects, many of which provide food for insectivorous birds during the nesting season. Conservation of mature oak woodland benefits the entire community of oak-associated invertebrates.
