チャックウィルヨタカ

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.

ハイイロイカル

灰色の上面、白みがかった下面、黒い頬ひげで縁取られた特徴的な白い喉を持つ中型から大型のずんぐりした鳥で、ハイイロフウキンモドキはメキシコから中央アメリカを経てボリビアとアルゼンチンに至る広大な分布域の森林縁辺部、庭園、二次林に生息します。適応力が高く、熱帯ラテンアメリカ全域の郊外の公園や庭園で繁栄しています。豊かで変化に富んだ音楽的な鳴き声を発し、撹乱された新熱帯の景観でよく観察される大型の鳴禽類の一つです。
