@NanoRaptor cycling by the river and a crow landed on the bike path in front of me, jumped in my way when i tried to go around so i stopped.
it jumped up and down until i dismounted and followed it to a nearby road where some of it's friends were squawking, all clustered around an endangered species of tortoise that couldn't mount the kerb to get to the river.
picked up the tortoise and walked it to the river, it swam off and the crows happily cawed and then all flew off.
