Our backyard bird feeders have attracted a Cooper’s Hawk. After the fact, I read some of the bird guides like Audubon and found if you put out seed in your back yard, there’s a good chance you attract the attention of a Cooper’s Hawk, because they mainly eat birds.
This hawk was quite fearless and let me walk up to within six feet of him before he flew away.
These medium-sized hawks are generally forest and woodland birds, but they are not unusual in the suburbs. They can be seen in parks, quiet neighborhoods, over fields, at backyard 
feeders and even along busy streets if there are trees around. Interestingly, our tiny goldfinches on the left hand feeder are safer than the medium sized birds attracted to the larger feeder. The hawk prefers meatier birds like doves and jays and will even sometimes go for small mammals like mice and squirrels.
hi this is Viggo I like the picture of the hawk.
