plovers act. pretend they're nesting when they're not, fake injuries to draw preteders away from chicks. and smart ones prank but they're real obvious about it. not like this. they've got this sense. like location direction spatial awareness, humans don't have it, it's why we always get in each other's way in a crowd just on the ground but birds do murmurations. or migrate half way round the world. now it's just... off. like an inner ear imbalance.
