We caught a couple of Burrowing Owls the other night. That make a total of 14 caught this fall. They are studying the owls because some spend the winter here and then in early spring, when mice populations are low, they eat Ashy Storm-Petrels. About 80% of the total world population of Ashy Storm-Petrels breeds on the island, so they need to keep an eye on the effect the owls are having. The amount of barring on the wing can help us tell the age of the bird, hence the following photo.
