The same friend who photoed this bird, photoed these little birds, in Clissold Park, two days ago, again with an iPhone:
One duckling in particular, really.
Guns didn’t cause birds to become more friendly, because the ones who did get friendly also tended to get shot. But birds survive being photoed, and are evolving rapidly into creatures that are no longer scared of us. Photoing birds may steal their souls, but they don’t care about that. They care about their next meal, and humans often supply this. Even humans with cameras, sometimes.
