They are pretty birds - and a bit too aggressive.
I gave up ever trying to get the better of crows, squirrels and starlings. I just relax and enjoy their antics.
Have you been to Wilco's they do a range that stops the larger birds. I have some and they are effective.
Beautiful plumage! Your third photo really emphasizes the iridescence of their feathers. How could they possible resist that tempting ball of tastiness ;)
Thank you for visiting. Hope you enjoyed the pictures. Any comment, or correction to any information or identification I get wrong, is most welcome. John
