If a surface area has an albedo of 10 percent and clouds an albedo of 90 percent then with 70 percent cloudiness the albedo for the area is 0.7(0.9)+0.3(0.1)=0.66=66 percent. This means that 34 percent of the Sun's radiation for the area is not reflected back into space.f a surface area has an albedo of 10 percent and clouds an albedo of 90 percent then with 70 percent cloudiness the albedo for the area is 0.7(0.9)+0.3(0.1)=0.66=66 percent.

Large mammals such as pigs, bears, and deer also consume large amounts of acorns; they may constitute up to 25% of the diet of deer in the autumn.
Other Predators. A handful of other animals prey on flamingos when the opportunity arises. These include raccoons and mink, who mainly eat eggs and newly hatched chicks, and large snakes like the python. In the Bahamas, wild pigs prey on flamingos on Great Inagua Island. In this rare case, the flamingo population has increased due to human activity, and the pigs have taken advantage of the abundant food supply. Domestic dogs have also been known to kill and eat flamingos that are being kept in captivity, such as at zoos.
