I just returned from Mono Lake where we observed a number of Yellow-
headed Blackbirds. Several of the Yellow-headed Blackbirds were
actually not yellow but rather orange in color. Is anyone aware of
why this color difference in the Yellow-headed Blackbirds at Mono
Lake? We suspect it is due to diet but would like to know if anyone
knows something definitive. I will post a picture to this discussion
group so any who are interested can see what I am referring to.
