chickadee in watercolor

Black capped chickadee

watercolor on paper

4" x 4"

I painted a chickadee awhile ago in soft pastels. This one is in watercolor and from a different reference photo.  The first one is an older bird. This one strikes me as a baby or toddler...what are baby birds called?  It's rounder, fluffier...like babies are...I don't know much about birds, but that's how I see it.
