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.

Cleopatra

The Cleopatra, Gonepteryx cleopatra, is a large, striking butterfly in the family Pieridae found across the Mediterranean basin, including southern Europe from Portugal and Spain east to Greece and Turkey, and extending into North Africa and the Middle East. The species is closely related to the common Brimstone butterfly but is larger and more vividly colored. Males display brilliant yellow-orange upperwings with a distinctive deep orange patch on the forewing, while females are pale greenish-white, resembling the Brimstone. The undersides of both sexes are pale green, providing excellent camouflage when resting on vegetation. The Cleopatra inhabits warm, rocky hillsides, maquis, garrigue, woodland edges, and citrus groves where its larval host plants, buckthorns (Rhamnus species), are present. Adults are strong fliers, frequently visiting flowers for nectar. Like the Brimstone, the Cleopatra overwinters as an adult, sheltering in dense evergreen vegetation during the coldest months and re-emerging on warm winter days. The species produces one generation per year. It is widespread and locally common across its Mediterranean range and is assessed as Least Concern by IUCN, though habitat loss from agricultural intensification and urbanization affects local populations.
