Why are . The supposed ravages of woodpeckers beneficial rather than otherwise? . Because they bore only those trees which insects have previously attacked, and thus diminish very considerably the numbers of such as are injurious to our forests. 798. Why are the extremities of the feathers in the tail of the woodpecker hard and elastic like whalebone, and with the shaft particularly prominent? Because this quality in the bird's tail affords a prop, or fulcrum, as it rests against a tree ; and n...o other contrivance could enable the bird to maintain its position when throwing back its head to give due force to the bill in hammering at the bark of the tree. 799. Why is tJie bill of the parrot so thick and powerful ? This member, so unlike that of other frugivorous birds, is admirably calculated for the principal offices it has to perform, viz. , breaking the shells and stones of the hardest fruits and seeds, and as a strong organ of prehension and support when climbing or moving from one position to another.
