One of the most intelligent and adaptable birds in North America. American Crows thrive in urban, suburban, and agricultural environments, forming large communal roosts in winter that can number in the hundreds of thousands. Their problem-solving ability and social learning make them highly resistant to conventional deterrents.
Tears open garbage bags and waste containers; plunders agricultural corn, grain and fruit crops; dense winter roosts cause severe noise and faecal contamination; predates on eggs and chicks of other species; vectors for West Nile Virus.

A murder of crows
Stems from medieval folklore where crows were viewed as omens of death and were believed to put "guilty" members of their own flock on trial.
A congress of crows
A reference to their loud, raucous group behaviour — historically likened to the noise and apparent disorder of a legislative assembly.
A parliament of crows
Comes from their loud, alternating caws, which historically reminded people of politicians debating in a legislative chamber.
At approximately 480 mm, the american crow fits a T3 — Large tunnel (130 × 500 × 630 mm). The tunnel is the physical entry point — sized precisely to admit the target species while excluding larger non-target birds. Species-specific attractant bait draws the american crow into the detection zone inside the tunnel, where AI computer vision confirms species identity at 99.7% accuracy. Once confirmed, CO₂ is introduced gradually into the chamber; the bird becomes drowsy and loses consciousness without pain or distress. Euthanasia follows only after explicit authorisation from a licensed operator, and the specimen is stored in the integrated freezing chamber with a full compliance audit trail.
The T3 — Large tunnel is available on the APC-N1 and APC-N4 — both units carry this tunnel size as a standard configuration.

Tunnel size is set by the species' standing height — sized to admit the target bird while excluding larger non-target species.
