I'm glad to find this group. I live in Western Massachusetts, in a wooded area with a pond and am just now beginning to learn the many many birds we have around us and appreciate learning more of their world. We are lucky to have numerous species in our locale.
I have always been led to believe that the different appearance in birds -- male/female -- is related to whether those birds mate for life or not. For example, birds which have a great distinction between male and female mate annually and birds which are more difficult to identify their gender mate for life.
Does anyone know if that is true?
Thanks to all for this group. I look forward to learning and sharing here.
