Two questions that are frequently asked are what size are eagle eggs, and what color are they? The photos above compare two bald eagle eggs that came out of the Norfolk Botanical Garden nest in 2008 to a tennis ball and a baseball. The shape of the egg is called oval. The two eggs with the tennis ball and baseball measured 74mm X 56mm. One weighed 126 grams (4.5oz) and the other 122 grams (4.3oz). The color is matte white. However it is normal for bald eagle eggs to become discolored during incubation. When nest material like pine straw gets wet it can stain the egg shells. You can see that with the two eggs beside the tennis ball and baseball.
The two bald eagle eggs in the nest in the middle photo above are the eggs in the nest now. The egg in front that is very white is the second egg that was laid yesterday Feb 3. The egg in back which is the first egg laid on Jan 31 is already slightly discolored. This is likely because the pine straw in the nest has been very wet from all the snow and rain, and because it was slightly less white when it was laid. There is also a piece of eagle down stuck on that egg from one of the adults.
