The Bismarck Crow (Corvus insularis) is a species in the genus Corvus. It is currently classified as Least Concern on the IUCN Red List. Typically found in various aerial, terrestrial, and aquatic environments.

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.
