You can befriend crows and, apparently, also train them to pick up trash by rewarding them with food.
Six crows trained to pick up cigarette ends and rubbish will be put to work next week at a French historical theme park, according to its president.
“The goal is not just to clear up, because the visitors are generally careful to keep things clean” but also to show that “nature itself can teach us to take care of the environment”, said Nicolas de Villiers of the Puy du Fou park, in the western Vendee region.
Rooks, a member of the crow family of birds that also includes the carrion crow, jackdaw and raven, are considered to be “particularly intelligent” and in the right circumstances “like to communicate with humans and establish a relationship through play”, Villiers said.
The birds will be encouraged to spruce up the park through the use of a small box that delivers a nugget of bird food each time the rook deposits a cigarette end or small piece of rubbish.

Software apps are a dime a dozen. Well, if you’re going by their actual monetary cost, maybe not really. But considering how useless some poorly conceived, poorly executed apps are at doing the job you actually downloaded them to accomplish, it isn’t a stretch to think that many apps aren’t even worth a free download. […]
With everything happening in the last few months, we all but guarantee no one has been thinking about their taxes. That’s understandable — because, beyond all of our current concerns, nobody enjoys the whole tax filing process during even the best of times. Unfortunately, Benjamin Franklin was right — taxes truly are as inescapable as […]
