Wildlife management has been revolutionized by the ability to track species in their natural habitats—to figure out what areas they actually occupy, where they feed, and so on. For years, that ability was limited to large mammals, which could easily handle the bulky batteries and electronics required to frequently broadcast location information. The miniaturization of electronics, however, has opened up the list of species we can track, adding birds and fish to it, and revealing the huge ranges covered by some species.

But now, some researchers have decided to turn the tables by placing hardware on birds to keep track of us. More specifically, our fishing fleets, which often operate in remote areas that are difficult to track. The work showed that albatross species could easily carry miniature detectors that would pick up radar and identification signals from any fishing boats they get within range of. This strategy is made even more effective by the fact that albatrosses are drawn to fishing boats.

The Pacific is immense, but it’s dotted with islands. Some of these create exclusive economic zones where one country has access to the fish stocks; there are also some large oceanic preserves. Outside these areas, any nation is able to fish, although some at-risk species may be covered by international treaties.
