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.

Coccora

The coccora (Amanita calyptroderma), also known as the California golden Amanita or the coccora mushroom, is a large, prized edible fungus in the family Amanitaceae, native to the Pacific Coast of North America from Oregon through California and into Baja California, Mexico. The species is especially associated with oak woodlands and mixed forests containing coast live oak, valley oak, and madrone, with which it forms ectomycorrhizal partnerships that are mutually beneficial—the fungus exchanges mineral nutrients for photosynthetically produced sugars from the tree's roots. The fruiting body is substantial and handsome: the cap ranges from pale yellowish-gold to rich orange-tawny, typically reaching 10–20 centimeters in diameter when fully expanded, with a smooth, sometimes patchy surface bearing remnants of the universal veil as scattered white patches. The gills are white and free from the stipe, and the base bears a large, sack-like volva from which the mushroom emerges—a characteristic Amanita feature. Despite belonging to the same genus as some of the world's most deadly mushrooms (Amanita phalloides, A. ocreata), the coccora is well-regarded by foragers in California, particularly within Italian-American communities who have long tradition of harvesting it. However, extreme care is essential, as it bears superficial resemblance to deadly species. The coccora is classified as Least Concern given its stable populations in western North American forests.
