Yeah, the Eurasian jay does this too, though they do it very defensively; they are often shy.

Jackdaws in the UK do it as well, but they definitely hang around like little gangs of urchins on people’s verges and front lawns; humans amuse them.

(They also grieve, despite what people say; I saw our local gang of six once, reduced to five, making odd quiet noises and unwilling to leave one of their gang that had been struck by a car and was quite obviously dead).

TIL. We hear and see the blue jays on our property frequently. We occasionally see a hawk but yet we hear hawk calls fairly frequently too. I always assumed I wasn't seeing the hawk. It never occurred to me another bird mimic the hawk calls. That's really interesting.
