Mockingbird

I last posted a picture of two baby Mockingbirds (one pictured above) on July 19th. Now four days later, one Mockingbird has left the nest, and this little one spent the day walking around the edge of its nest. I could not believe the difference four days has made.
I will note, yesterday, both baby birds were still in the nest. I'm not sure what tomorrow might bring...perhaps an empty nest???
