Birds eat a lot of things, and can be quite mean to other animals that comes in their way. Now, a German research team has recorded for the first time ever that when food is scarce, great tits can actually prey on bats. And it's quite grusome: the bird starts to munch before the bat is dead, which doesn't happen until the bird has pecked open the head of the bat. Not really a Walt Disney movie.
There's a video for you at New Scientist! I can't help it, but this story makes me smile because people tend to view these "cute, little birds" as nice and vunerable creatures, while other birds such as the Rook (Corvus frugilegus) is regarded as a mean scavenger not worthy of your bread crumbs. I will definitely keep this story in mind whenever this topic comes up....
