There's significantly more than that amount. They started a few weeks before Thanksgiving and continue to wreak havoc on our neighborhood and entire area. They just keep moving from one property to another, damaging flowerbeds, lawns, bird feeders, cars, you name it. The sound is horrible; it's similar to a train wreck with the constant screeching. I finally was able to capture a bit of it today with the camera. Whenever we see them moving onto our property - I go outside and clap loudly four or five times and they move on. The children love it...but I hate them.
