http://birdwatching.wetpaint.com/I have been studying birds and their behavior for about 36 years. I have found that this is a life long quest to be able to identify different birds not only by sight but by their songs too. There are many different aspects of nature that I am interested in and hope to share and learn from you. Thanks, Mark....Hutch

I also find the followings links very helpful in this quest;
