Osprey nest

Last Tuesday Bob T. and I walked to Divide Meadow while the others did their run. One of the sights to be seen on this walk is this osprey nest, abandoned at this time of the year. I'll check it again in the spring. Wikipedia describes the osprey:

The Osprey (Pandion halites), also called Sea Hawk, is a diurnal, fish-eating bird of prey. It is a large raptor, reaching 24 inches in length with a 6 ft wingspan. It is brown on the upperparts and predominantly whitish on the head and underparts, with a brownish eye patch and wings.
The Osprey tolerates a wide variety of habitats, nesting in any location near a body of water providing an adequate food supply. It is found on all continents except Antarctica although in South America it occurs only as a non-breeding migrant.
