Book excerpt: Excerpt from Birds That Eat the Cotton Boll Weevil: A Report of Progress During the growing season of cotton the adult weevils are concealed the greater part of the time on the buds, or 'squares, ' where the enfold ing bracts afford almost complete protection from most of their enemies; this fact largely explains why comparatively few weevils are eaten by birds during the summer months. The amount of time they spend on the wing and the distance they fly from place to place are not well known, but it is only during the period of maximum infestation that any considerable proportion of the insects can be found in exposed situations. After the first hard frost, weevils begin to leave the cotton plants and seek sheltered places in which to hiber nate. During this period their numbers are materially reduced, but in favored seasons many weevils successfully pass the winter in their retreats. Rubbish piles about the borders of fields apparently furnish the most desirable hibernating quarters, and in such situations the weevils are exposed more or less to the attacks of ground-feeding birds. They are said to make use also of the hiding places afforded by the cotton and corn stalks which have been left standing. Investigations thus far made show that while fewer weevils are destroyed by birds in winter than in summer, the number of Species of birds that feed upon them in winter is somewhat greater. The birds which eat boll weevils in winter and spring and up to the time of the breeding season of the insects are more important economically than those which eat them in summer, for the reason that during the season of nonactivity of the weevils a relatively long period must elapse before they can make good the losses in their numbers, while during the breeding season weevils multiply with astonishing rapidity.
