Mid-March Backyard Point Count

The backyard bird community is in transition as winter resident birds are getting ready to head to their summer breeding range, year round resident birds are setting up their territories and beginning to build their nests, summer (breeding) residents are starting to arrive, and neotropical migratory birds from Central and South America are slowly beginning to pass through Georgia on their way north to their summer breeding grounds.

Once or twice a week I will do an early morning bird count to see what birds are waking up in our backyard. Over time we will be able observe the transition of the backyard bird community.

Here is this morning's 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.
