Field notes

  • It is notably small for a corvid, measuring roughly 14 inches, which is closer in size to a Blue Jay than an American Crow.
  • The plumage exhibits an intense, silky blue or violet iridescent sheen that is more prominent than in most other crow species.
  • Unlike the typical 'caw' of its relatives, its voice is a low-pitched, guttural croak that sounds remarkably like a frog.
  • It was first recorded in the United States as recently as 1968, appearing at a landfill in Brownsville, Texas.
  • It is highly social and gregarious, often foraging in large flocks that can number in the hundreds outside of the breeding season.
Habitat
Arid lowland scrub, brushy fields, farms, and urban outskirts.
Range
Northeastern Mexico (Tamaulipas and San Luis Potosí) and the extreme southern tip of Texas.
