There goes more jobs to migrant workers?!?! Yes, it seems now that crows, already trained to use coins in vending machines for the reward of some peanuts, are now potentially to be trained and deployed to pick up litter.

The best part is, only a small number of these feathered friends would have to be trained, then released. The study in question showed that these trained fowl teach these learned skills to both offspring and peers--and they'll all, quite literally, work for peanuts!! I s'pose that city worker with the bag and spiked stick will have to find work elsewhere . . .
And if you're not pissed off about more local jobs going to the birds, how will you feel when a murder of crows (i.e., like "gaggle of geese") siddle up next to you at the bar and proceed to poop in your complementary popcorn!?!?
