I have been noticing and enjoying birds lately. my garden has soem great robins and blue birds and the occasional cardinal, and I see hawks pretty often. yesterday I saw 30 hawks on a tree about 5 pm. I don't know what type of hawks they were, but they were about 15 inches tall. I noticed them because I saw about 10 in the air in one place and watched them land, and then counted the ones already landed. I find hawks very cool, because when I was a kid they were so rare. as I understand that they are not social animals, anybody here know anyting about birds and may know why all these birds would be together?
