There was a crowbro community on reddit. You made me remember a community i kind of miss here. We take walks around the neighbourhood and i never leave without food for the crows, jackdaws and magpies. One jackdaw pair lives across our house and as soon as i leave the house, he will wait for me. If i overlook him, or am in a rush on my bike, he will cut me off by flying right before my wheel. He learned that i will stop and give him treats. Now, some of his kids have learned it too.
There is also a crow who saw how we fed his parents. So, now, we have been feeding him for a couple of years too. He has a partner and when she notices us, she will call so that her partner knows there is food to be had.
It's great to walk around, knowing that you make so many birds happy, which makes us happy too.
