1st Day of Spring Backyard Point Count

This morning's backyard bird count yielded 16 year round residents, 4 winter residents, and 1 summer resident. Soon we should start seeing more summer residents arrive and neotropical migrants pass through on their way north. We will also begin to see less winter residents as they begin to make their way north as well.

Here is this list. I have indicated if the bird is a year round resident, winter resident, summer resident, or a migrant just passing through. I have also indicated the conservation status of each species.
