I found the red-tail hawk.

5. They eat their own, as well as small pets.

I remember having parent/teacher conferences on a half day schedule with the parents of my 1st graders. While a parent and I were speaking I looked at her face, which was facing the open classroom door which was under big Pine Trees. I turned around to see why her mouth was hanging open...a Red Tailed was pulling the feathers out of a dove that was its victim. It looked like snow was falling, big lightweight snowflakes. We both said at the same time, "thank goodness the kids aren't here to see this".

At a park close to my home I would take my dog to roam about and many times, with both of my Chihuahuas, I would look up and see a bird...silent and circling above for a long, long time. My friend told me it was a hawk and to grab my dog. I laughed it off...he obviously was exaggerating. I was wrong. That bird circled over my dog for at least 15 minutes without flapping it's wings once. It just glided all over the hills and valleys for a long time. It was impressive but scary. After that I made sure to look out for them when we we to the park.
They even attack other, smaller birds in the heart of the city. My neighbor knocked on my door once to warn me to keep my dog inside since a Red Tailed Hawk was pulling the body of a dove apart right over my apt. in front of our eyes.
