Sulawesi Crow Corvus celebensis

Medium-sized black crow with a relatively long, slightly decurved bill. Plumage has an iridescent dark blue sheen when seen up close. Due to absence of generally more adaptable Large-billed Crow on Sulawesi, this species can be found in both intact lowland forest as well as somewhat more degraded and fragmented habitats. Often encountered as pairs or small flocks in rowing flight over roads, rivers, and clearings. Gives loud nasal caws, often with a rather dry quality. Formerly treated as part of a more generic “Slender-billed Crow” that ranged from the Philippines to Sulawesi.
