PORTLAND, Ore. (KOIN) --- The Oregon State Veterinary Diagnostic Lab and Oregon Department of Fish and Wildlife confirmed this week that the dead crows seen around the city earlier this year were indeed poisoned.
Residents reported seeing the birds falling out of the sky on January 30 and the days that followed. The crows were spotted in the area of Martin Luther King Boulevard and NE Jessup Street, and multiple agencies collected at least 10 dead crows from that multi-block region. Another dead crow was seen in the Park Blocks in downtown Portland.
Officials say they performed tests and found a neurotoxin called Avitrol. Avitrol is toxic to mammals and birds.
Officials say the person who poisoned the birds violated federal laws. A suspect has not been named.
