Chip
Last month, I saw this juvenile crow at my apartment complex--note the chipped beak:
I fed it, and the other crows, some nuts and peanut butter pretzels. Then, for a few weeks, I didn't see the crow with the chipped beak at all-- until this week:
The crow's neck feathers have grown in nicely, and its beak appears to have healed slightly but still have a distinctive indentation. (According to crow expert Kaeli Swift *, broken beaks can regrow if the breakage only affects the outer keratin cover, not the underlying bone, as seems to be the case here.)
* An ornithologist named Swift is a fine case of nominative determinism. I also know of a marine biologist named Helen Scales, a TV weather forecaster named Dallas Raines, and (my personal favorite) a 19th-century psychologist named Sir Henry Head.

Spy crows
THE United States military funded research into using networks of 'spy crows' to locate soldiers who are missing in action, and extended the work to see if the birds might be useful in helping them to find Osama bin Laden. The idea may seem far-fetched, but unlike some military research programs (such as the Stargate remote-viewing program) it is actually based on sound science.From Neurophilosophy. See here for more on the intelligence and memory abilities of crows.
