The Perfect Perch ~

The cypress tree in my front yard is the tallest tree in my neighborhood so it is an ideal perch for birds. At night I often hear an owl's hoots. As I was leaving my house I was startled by a loud squawking and I saw this raven (?) or crow (?) making a lot of noise way up at the tip top. I am not a birder so if you can identify this as a raven or a crow, please post your knowledge!
