Tiny little cameras were attached to albatross as they flew around over the open ocean hunting. This is important because it is really hard to study albatross at open sea, and virtually impossible to follow individuals one might like to track from, say, a nesting grounds out many miles (they fly fast and far). By attaching cameras, temperature and depth gauges to the birds one gets some VERY interesting results.
I’ve written a review of a paper that just came out in PLoS on this topic and posted it at Surprising Science, here. Please have a look.
