Went out today at about 2pm and found a raptor perched on a line staring at my chicks. It flew off with its mate when I showed up and tried to take a picture. We live in a very urban environment and I've never seen a raptor out here (Oakland, CA in the flatlands). After some internet searching, it seems we have mated pairs of peregrine falcons nesting all over the bay. I was planning to let the chicks out of the run to roam the yard eventually, but now I'm no so sure -- should I be worried? Has anyone had a raptor attack in the city?
