There are a lot of blue birds, but most of them down have a “B” in their names. These were the only ones I could think of of which I had any pictures. Bluebirds, Blue Jays, and the Great Blue Heron.
I couldn’t even think of a bird with a B unless the B can be in the middle of the word. I was assuming as the title of the name, first letter. But these blue birdies are sweet anyway.
