Oh yeah, there is a story about "Pale Male" the famous redtailed hawk that has decided to make a home in New York City, subsisting on the abundant rats and pigeons within the city and Central Park. Unfortunately, his mate was killed by people who spread poison to kill the pigeons. Looks like your juvenile Cooper's hawk has killed a pigeon as well.
Scene in my backyard this morning. Yes, we have exotic "boids" in New
Lucky my D300 was nearby, loaded and ready to go. The hawk flew away
with its catch in about a minute.
