The elephants supply a place for the birds to nest and reproduce.
The elephants supply a much needed food source by allowing the birds to
eat bugs off their backs.
The elephants provide diversity in ecosystems by carrying the birds long
distances as they travel in herds.

forth from their local watering hole.
