noun
carrion crow
Refers specifically to Corvus corone, a species of crow found in Japan and Eurasia. Often distinguished from the larger ハシブトガラス (jungle crow).
公園ではしぼそがらすが餌を探していた。
A carrion crow was searching for food in the park.
ハシブトガラス is the jungle crow (Corvus macrorhynchos), which has a thicker bill and a more domed head compared to the carrion crow.
Compound of 嘴 (はし, 'beak') + 細 (ぼそ, 'thin') + 烏 (からす, 'crow'), literally 'thin-beaked crow'. The exact historical derivation is uncertain, but the name describes the bird's relatively slender bill compared to other crows.
