|My snowy bird feeded this morning.|
A few years ago I happened to be surrounded by three male chickadees doing their call. One female was in the area. These little guys really called with all the vigor they had. The female went and took a look at all three callers and then flew out of the territory. She could probably hear anther male calling which my ears were not able to detect. The three males she visited all called after her as if to say come back and take another look at me.
So some people see robins as the perfect indicator of spring. Others see first green plant shoots of some kind as their sign of spring. Other people have a favorite blossom which to them indicates that spring is here. For me the little chickadee is all I need to hear for a sure sign of spring.
