        　　We've just seen two ______ large birds that cannot fly: the ______ and the
______. Over here is an interesting ______ from the past. This ______animal is
not the giant ______ it appears to be, but an ______. This particular kind of
auk is very rare, only 78 skins are known to exist and most are not preserved as
well as this one. The great auk, as you can see, was a rather large bird, and it
couldn't fly either. However, evidence suggests that the auk was an excellent
swimmer and diver. Unfortunately, those abilities did not protect it from being
easy prey for hungry sailors who years ago sailed the very cold and often icy
waters of Greenland, Iceland, and Scotland. In fact, records indicate that the
auk was rather tasty and that its eggs. Excuse me . . . that its eggs and
feathers were useful as well. Still, it isn't clear what other factors led to
the big bird's ______ around 1844, the last time anyone reported seeing one. Of
course, we believe it's important to take extra ______ to preserve the remaining
great auk skins. After all, these specimens should prove ______ for future
scientific research. Does anyone have any questions before we move on to our
next bird exhibit?
