Please allow me to try to help anyone understand about Grackles. As noted by "The Pete" it is a black colored bird with an oil slick on water type of candy coated coloration on the head to shoulder region. They are slightly larger than a pidgeon but smaller than a magpie, though no less annoying than either. Although looking like a miniature raven, the grackle has nowhere near the intelligence made famous by the Edgar Allen Poe tome. The tail is held in a distinctive V shape when in flight, but there's nothing else worth mentioning about the bird.
Most States outlaw hunting of grackles as they seem to be mistaken as songbirds, but those States that disallow full scale eradication of them are governed by Liberals.
I wouldn't hunt them anyway as the meat is slightly less desirable than skunk. Grackles are definitely not what are referenced in the "Four and Twenty Blackbirds" that were baked in a pie in the children's rhyme.
Even though you may not be familiar with the term 'grackle' you can easily recognize this as the bird that jumps around in fast food parking lots fighting over spilled french fries.
A very little known fact. Almost all automotive manufacturers codename a new car in development to keep the media and buying public in suspense, and even confused at times. Yup, you guessed...the CBR XX Blackbird was codenamed the 'Grackle'.
I hope this helps clear up the confusion over biology major Pete's explanation.
