Where do the slate-colored juncos go in the warm weather? It is still relatively cold and they still are in the yard feeding on the birdseed on the ground. There are less of them. I know they will disappear when it gets warmer and no more snow. I thought I read they migrate further north. I am really curious. I have to look it up in one of my bird books. It is usually the other way around. Some birds migrate when it become colder. Not those birds. They usually arrive when the first snow comes. It is a mystery to me.
