Nest Design/ Mother Lifting-Off
The nesting platform adds a layer of man-made defenses to the natural defenses discussed on the previous slide. The predator guard (coned-shaped metal below cross members) at the bottom prevents raccoons and snakes from entering the nest. Osprey often build on electric poles which have the obvious potential for electrocution which the platform does not share. Our nest is "Y" shaped to help osprey imprint to crooks in trees when seeking a natural nest. The "Y" is also designed with the arms projecting over the nest so the adult birds can assume a threatening position above the young as a deterrent to aerial predation (owl attacks). Lastly our platforms are less likely to collapse, although these birds have been over-zealous builders so we are concerned with possible instability due the sheer mass they’ve added to the nest this year.
