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.

ムジボウシインコ

アマゾンオウムの中で最大級の種の一つであるコナフキリインコは、青灰色の頭部と羽毛に独特の粉をまぶしたような光沢を持つ繊細な粉緑色の羽毛が特徴で、この特徴から名前がついた。メキシコ南部から中央アメリカを経てボリビアおよびブラジルまでの南米大部分の低地熱帯林に生息する。つがいや小群れで移動する。世界的には軽度懸念種だが、生息地の消失やペット取引の影響を局地的に受けている。
