Do
you see the yellow corners of the mouth?
- The corners
are called are called the "gape." They are made of
very soft tissue. The wide mouth gives a bigger target for
parents helping the babies to eat. A wide mouth makes it easier
for the babies to gulp large fish parts. As the beak grows
with the growing bird, the gape slowly shrinks.
Can
you peek into the mouth and see its tongue?
- Eagles use
their tongues to help them swallow, just as we do. But their
tongues are not as long, so they can't stick them out at each
other the way we can!
An eagle usually
keeps it mouth shut. When they are hot or nervous, they open
the mouth to pant.
- It
looks like a sunny day up here, so the eagle may be warm.
- Or
it might be nervous about having a photographer staring at
it.
