Crows and other members of the corvid family, such as rooks, ravens, jays, and magpies, have individually distinct voices. This is because crows produce loud vocalizations of much lower pitch than most birds, making it easier for humans to recognize individual crows. Scientific studies have shown that adult corvids have a wide variation in their voices, and rooks have their own repertoire of calls that are distinct from those of other males. Individually distinctive voices are especially important for social species like corvids, where multiple individuals live together for extended periods. [Extracted from the article] |
