It looks like our last chick has fledged! The trio will return to the nest, as it provides a safe, familiar place to rest (and eat). Oliveea will contine to provide the fish until her young master the art of fishing. Fledged ospreys have been known to catch fish as early as 74 days after hatching. They learn to hunt mostly by watching their siblings.
In response to some of your comments, the spider webs on the camera lens will be cleaned off later in the year after the ospreys leave the area.
