Woodpeckers

• Yet in North America there are woodpeckers which feed largely on fruit, and others with elongated wings which chase insects on the wing. 查尔斯·达尔文. 物种起源.
• The beak, however, is not so straight or so strong as in the typical woodpeckers but it is strong enough to bore into wood. 查尔斯·达尔文. 物种起源.
