We can ID this sparrow as a American Tree Sparrow as follows:
- Plump with long notched tail.
- Rufous crown and rufous back.
- Bicolored bill.
- Dark spot in center of chest.
- Has two bright white wingbars, but in the poses in these photos you can only see the longer wingbar, not the smaller one nearer the neck. This is consistent with a number of photos on the internet.
The American Tree Sparrow is a new species to our Life List, which now stands at 281.
