Collared Crow

<em>Corvus pectoralis</em>, the Collared Crow, is a large corvid in the family Corvidae. This species is classified as Vulnerable on the IUCN Red List, indicating a high risk of extinction under current conditions. It is documented in Taiwan and is also found in eastern China, inhabiting lowland areas including river valleys, agricultural land, and coastal regions. The Collared Crow is named for the distinctive white collar that separates its black head and upperparts from its white underparts. Members of the genus <em>Corvus</em> are known for high intelligence, omnivorous diets, and adaptability to human-modified landscapes. Despite this adaptability, <em>Corvus pectoralis</em> has experienced significant population declines, likely attributable to habitat loss, hunting pressure, and possibly competition with other corvids. Diet, population estimates, and biological measurements including average length, weight, and lifespan are not specified in available records. Biological traits of this species remain poorly documented in the scientific literature. Its Vulnerable status underscores the need for targeted conservation actions within its range.

ワタリガラス

最も知能の高い鳥の一つとして知られるワタリガラス（Corvus corax）は、道具の使用・計画・欺瞞行動など大型類人猿に匹敵する問題解決能力を示す。北極のツンドラから砂漠まで北半球全域に分布する適応力の高い雑食性種だ。複雑な社会階層を形成し、協力して採食し、遊び行動も観察される。高い知能と黒い羽毛から多くの文化の神話に登場する。
