is to a site that holds a bird watch each yr. The dates to watch are feb18-21. I have a bird feeder up all yr and can see it from 2 places in my house. All you do is watch what birds are in your yard and count them, if you go to the site the info is all there. Anyway, I thought there might be some bird people in the group. sharet
