'Intelligent' crows to pick up litter at French theme park

Is there any consideration for the health effects of carrying a carcinogen in their beaks? Cigarette butts are _nasty_ and also poisonous.

Your comment sounds a bit hyperbolic.

I guess eating them isn't going to be good, but is picking them up and depositing them going to be poisonous to the crow?

I think it's what the above poster was specifically asking. Is this safe for the crows? It's a cute circus trick, but has anyone checked that it's actually safe for them?

As far as I am aware it is only inhaling the smoke that is carcinogenic. That being the case, just holding a butt in their beak should be safe.
