They don’t start out life all colored in.
A short while ago, I published an image of a spectacular male Wood Duck keeping a watchful eye on his brood. There was good reason to be watchful: There were so many of them!
The female Wood Duck and her brood had taken a break from swimming the river, jumping up in a lineup along a fallen tree. There was a bit of a tussle as they scrambled up among the turtles that had been sunning there, but eventually everybody seemed to fit in and settle down.
If you look carefully toward the right side, you can see a bit of yet another young duckling. There may have been a couple of others there… I lost count after a while.
