Once again, I seemed to see White Wing get chased away by the adults and I was feeling very sorry for her.
It got worse as the neighbours, the Unbrave Two (Four was absent) decided to have a go. You can see one of them - the distorted shape in the foreground.

But at that point, the Divines rose to defend their mutant kid.
Then I began to wonder if, in fact, they chased off all three kids and it's just that White Wing is the most persistent or annoying?
When I watched for longer that seemed plausible.
White Wing has such stark white stripes that I mistook a cheeky magpie for the cheeky crow!
Another day, I saw the Divines chase off a seagull and realised that their annoyance with the kids is pretty tame in comparison.
Then, a few days later, I saw a crow half a mile from the park with even whiter wings than White Wing! The whole lower half of the wing, top and bottom, is white! Could that be the father?
Great to get crow reports. We don't have magpies. Is the only video with the magpie, the last crow video? I've seen pics of magpies and know they have lots of white on them, not just the wings. You have lots of material for an illustrated story book :-)
