During the summer months the tundra is literally infested with flying insects and has a large population of insect-eating birds. Many, like the pilofile, have bristled beaks - a ring of stiff hair-like feathers surrounding the beak that forms a cone and deflects insects into its mouth. The bristles in effect widen the bird's potential capture area and increase its food supply.
