Greetings All



Entirely purple grackles in the west almost invariably are GT Grackles or GT Grackle x Brewer's Blackbirds. Penny, if you are most familiar with grackles from AZ and south Texas, it is probably Great-taileds that you know best.




In any case, the east coast version of Common Grackle has never made it to the Mississippi River, as far as I know, and is extremely unlikely. If not GT Grackles, there was a bird rather similar to a "purple" Common Grackle in the SF Bay area (I believe) that was well documented and turned out to be a GTGrackle x Brewer's Blackbird.
