I work in 911 dispatch, and apparently we have a couple emu farms in my area, and at least one rich asshole who just has one as a pet.
And one of them manages to get loose maybe once every year or two on average.
So we have a weirdly thorough document about loose emus, the best ways to approach them, the ways they'll attack if they feel threatened, what vets and animal rescues and such are willing to help catch, tranquilize, house, and treat an emu, what to feed them, etc.
And a note that the state game commission will not assist because it's not a native bird.
But what's especially baffling to me in that very often we have no idea where these emu came from, we call around to all of the farms and rich assholes in the area, and they'll all say that their entire flock is accounted for. A couple usually offer to take it off of our hands if no one else claims it. Before I started there was one that was loose for months we kept getting calls about that they were pretty sure was someone's pet because it had approached people looking for food and attention a few times, but no one reported one missing, stepped forward to claim it, and even though it was a pretty big local buzz in that area we didn't even get any tips like "you know, John Smith over on Maple Street used to have an emu but I haven't seen it out in his yard in a while"
