Nature Done Wright

This appeared last Wednesday on the Op-Ed Page of The New York Times:

An Op-Ed essay on Monday described bald eagles and ospreys incorrectly. They eat fish, and their poop is white; they do not eat berries and excrete purple feces. (Other birds, like American robins, Eurasian starlings and cedar waxwings, do.)

I am guessing that the berries were pokeweed.
