Cool photos Susie. Thanks! Yes, the Starlings are invasive birds. I like to relate this story which the actor michael Caine told in his book. Starlings are so much of a pest bird in Britain that they have long had a bounty on their heads. When Michael Caine was a kid he hepled the family finances by shooting Starlings & collecting the bounty. I can't remember exactly but I believe he said it was 6 pence & that was back around the time of WWII.
