Question 18-31
In the world of birds, bill design is a prime example of
evolutionary fine-tuning. Shorebirds such as oystercatchers use
their bills to pry open the tightly sealed shells of their prey,
hummingbirds have stiletto-like bills to probe the deepest
nectar-bearing flowers, and kiwis smell out earthworms thanks to
nostrils located at the tip of their beaks. But few birds are
more intimately tied to their source of sustenance than are
crossbills. Two species of these finches, named for the way
the upper and lower parts of their bills cross, rather than meet
in the middle, reside in the evergreen forests of North America
and feed on the seeds held within the cones of coniferous trees.
The efficiency of the bill is evident when a crossbill locates
a cone. Using a lateral motion of its lower mandible, the
bird separates two overlapping scales on the cone and exposes
the seed. The crossed mandibles enable the bird to exert a
powerful biting force at the bill tips, which is critical for
maneuvering them between the scales and spreading the scales
apart. Next, the crossbill snakes its long tongue into the gap
and draws out the seed. Using the combined action of the bill
and tongue, the bird cracks open and discards the woody seed
covering action and swallows the nutritious inner kernel. This whole
process takes but a few seconds and is repeated hundreds of
times a day.
