I'm afraid you've upset my friend , Ron. He doesn't like his true colours questioned and any reference to purple cows just puts him in a snit. We do have some blackbirds that turn every colour of the rainbow depending on the light.
This fellow showed up at the feeder a week ago. Each morning he arrives for an early breakfast . He looks marvelous but kind of lonely. There are no signs of other males or females and as far as I know he isn't supposed to be in the province at all.
