Golden colored coral.
A bit larger then a baseball.
It came free from the leaf litter in which
it was growing.
To me, it looks like 4 of those ducklings
are not hers :o)
Another thought is that this is a hybrid bunch of chicks. I read that Mallards and Black Ducks interbreed. The hybrid when it breeds will have a more variable colored chicks.
Taken with a 12x telephoto lens. This detail was not visible to the naked eye.
Look at the 4 yellow once on the left. They are a bit larger then the others.
