Compassionate but not smart. She put her open mouth on an ‘unknown’ pigeon? That could have been a really dirty bird.
Besides that, the deceased appears to already have a broken neck, so CPR is not going to help it. Not enough time and available equipment for a sidewalk tracheotomy.
Can you get pigeon disease from a live/recently deceased pigeon? Or is it caught from old, moldy piles of pigeon poop?
