Posts Tagged ‘osprey nest building’

Real estate is at a premium in Northern Virginia, and new houses are jammed into the tiniest of spaces. Unfortunately, this channel marker did not appear to be quite big enough to support the nest of an osprey couple. During a recent visit to Occoquan Bay National Wildlife Refuge I watched the ospreys (Pandion haliaetus) carry a number of sticks to the marker as they unsuccessfully attempted to construct a nest—most of the sticks simply fell off the sides of the marker.

I was delighted on Friday to see that Ospreys (Pandion haliaetus) have returned to Occoquan Bay National Wildlife Refuge. Each autumn we bid farewell to the ospreys, which are also known as fish hawks or sea hawks, and each spring we greet their return.

Unlike eagles, which use large, well-constructed nests year after year, ospreys seem content to throw a bundle of sticks together and call it a nest. Many of these makeshift homes are blown down or fall apart during the winter, so a first priority for the returning ospreys is to construct nests.

During this visit I managed to capture several photos of ospreys overhead in flight with branch in their talons. As both photos show, ospreys often grab branches at one end, rather than in the middle where the weight would be better balanced. I am amazed by the ability of the ospreys to fly so well with those long trailing branches, though I suspect that the branches weigh a whole lot less that the fish that I hope to see them catch later in the season.
