Interesting Fact: Pied-billed Grebe

Did you Know? . . . that Pied-billed Grebes continually pluck and consume body feathers which helps protect the stomach lining from the sharp bones of fish and other vertebrate prey.  This results in the continual replacement of body feathers which means that the grebes are always growing new feathers.  This same technique is also used by other grebes.

Interesting fact about PBGR. I see them a lot at my local patch but I haven't observed this so far. Will have to watch for it!

I recently read this too. I haven't observed the behavior, but it'd be pretty neat. I'll definitely be keeping a look out in late spring when they'll be teaching their chicks how to eat feathers.
They say you're not a full adult Grebe until you've consumed a 1/2 pound of your own feathers...
