http://www.learner.org/jnorth/maps/Maps.html They follow other birds too and the monarch butterfly. I joined the site and put in my information and went to check on the map...for my location. We haven't seen a robin in a long time and I was surprised that other people in Illinois, near Chicago, still were seeing them.There was no information on Juncos, however. I wish that they would track these little favorite birds too...I am on the watch for these little ones who stay here through rain, snow, sleet and all kinds of bad weather. Our tough little Juncos will be here soon.My neighbor,who lives in Minnesota in the summer,will be home in a week or so. Snow is predicted for them today and when the snow flies...they head south for home. Glad that they are coming home early...they will get to see our fall color show here in Byron.
