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.

Common stork's bill

<em>Erodium ciconium</em>, the common stork's-bill, is an annual or biennial flowering plant in the family Geraniaceae, order Geraniales. It is native to the Mediterranean region and southern Europe and has been introduced to parts of North America. The species typically inhabits dry, disturbed habitats including roadsides, cultivated fields, rocky slopes, and coastal areas, favoring sandy or calcareous soils with good drainage. Its pink to purple flowers are relatively small, and the distinctive elongated fruit resembles a stork's bill, a characteristic shared across the genus <em>Erodium</em>. The beak-like fruits are adapted for wind and animal dispersal, with hygroscopic awns that drill the seed into the soil through coiling movements in response to moisture changes. Biological traits such as typical lifespan duration, average biomass, and detailed dietary associations remain poorly documented at the species level. <em>Erodium ciconium</em> has not been formally evaluated by the IUCN, though it is generally considered a common species without significant conservation concern across most of its range.
