The science of crows
At breakfast this morning: Dad: I was reading New Scientist, and they were looking into how crows can survive swooping in front of vehicles. Apparently they use a sentry, while another swoops in to collect the roadkill.
Me: Oh, that's pretty cool
Dad: Yeah, but they don't dodge trucks.
Me: Why's that?
Dad: well, when the sentry see the car it goes "Caaarrr, caaarrr!". But they can't say truck if they see one.
