Is an alliteration because the sounds are the same. On the other hand: Cheerful cop. It might begin with the same letters, but it is not alliteration because the sounds are not the same.
Q. About how long does it take for the bald eagle's eggs to hatch and how long until it can fly? A. It takes 35 days to hatch, then young in nest 10-12 weeks more unti lthey fledge (fly from nest).
The eggs take almost precisely 35 days to hatch. Since the incubation starts from the time the first egg is laid, this means that the eggs hatch 3 days apart. The average for the west coast eagle populations is almost exactly 2 eggs per clutch.
