Inone Kenyan study, scientists noted that without vultures, carcasses took three times the standard amount of time to decompose. Scientists estimate that perhaps only a few hundred pairs remain in the wild. As part of the process, they loosen up the soil, promoting better air circulation and water filtration. Habitat destruction and degradation, illegal shooting, and the contamination of its food source, due to use of the pesticide DDT, decimated the eagle population. They munch on their favorite berries, and then distribute seed-strewn droppingsensuring thatnew plants continueto sprout up. Although capable of killing large prey such as cranes, wild ungulates, and domestic livestock, the golden eagle subsists primarily on rabbits, hares, ground squirrels, and prairie dogs. Flora then becomes a food source for birds, animals and insects. In addition to the adverse effects of DDT, some bald eagles have died from lead poisoning after feeding on waterfowl containing lead shot, either as a result of hunting or from inadvertent ingestion.
