We have had three species of sparrows feeding recently in Bird Alley. The white-throated Sparrow is a daily visitor and is often the first arrival of the day.
is the little northern Tree sparrow. There are two strong identifying features of the Tree Sparrow. First, look for the bicoloured bill which has a lower yellow bill, and secondly the tree sparrow has a central dark breast spot.
the third sparrow that I found in Bird Alley about a week nd a half ago was a Song Sparrow, but with this recent cold snap it hasn't been seen since.Hopefully this lingering sparrow is now headed for more southerly climes. As the Tree Sparrow, the Song Sparrow also has a center dark breast spot to identify it.
