I would hope so because watermelon is actually my favorite fruit. However, disregarding my personal preference on the matter, dogs can in fact eat watermelon.
Bald eagles have also been seen stealing prey from other birds in mid-air, particularly osprey. Bald eagles are among the largest raptors in the United States, second only to the California Condor. They measure from 28 - 40 inches in length, or about 2.5 - 3.5 feet. The wingspan can reach from 72 - 90 inches, or 6 - 7.5 feet. Females of this species are slightly larger than the males.
According to Eagle Nature, the American bald eagle's diet consists of 60 to 90 percent fish. Most of this is scavenged as dead fish, though bald eagles do hunt and catch live fish as well when they are available. The type of fish caught depends on location; eagles typically hunt and scavenge whichever type of fish is prevalent. Mullet and black fish, which swim near the surface, are likely prey.
