Whose Nest is This Anyways?

Osprey are birds of prey with a wingspan more than 5 feet across. These large raptors construct huge stick nests that get up to 6 feet wide and 12 feet tall! While the Ospreys only occupy the upper portions of this structure, other birds have been observed taking up residence in the nooks and crannies below. This unexpected living arrangement is a classic example of protective nesting. Nesting birds – be they songbirds or raptors – must always be on the alert for egg-eating predators. But with pescatarians in the penthouse suite, the nests’ smaller tenants get 24-hour security without ending up on the menu themselves.
