It contains audio I have created and photos I have taken (at least most of them). It's designed for youth/beginners that want to learn about birds and their songs.
A Winter VisitorI also have a winter visitor in my yard. I usually keep track of the date when they show up in winter. Of course I am talking about a bird. It is a sparrow a bit smaller than the typical house sparrow. It is an American Tree Sparrow that breeds in the north.
Note its bi-colored bill, white wing bar and button on its breast.
