Stan Delivers Half a Tree!
Osprey are described as “Prodigious builders”. It is generally the male that brings the bulk of material to the nest, the female arranges it once there. They may break dead sticks off nearby trees in flight or (more often) snatch from them from the ground. The nest is generally constructed from large sticks (about 2–4 cm diameter; up to 1+ m length) at the base, with smaller sticks and a great variety of grass, algae, flotsam, and jetsam from there. As the nest nears completion, they appear to shift markedly to flat objects: paper/plastic bags, mats of algae, bark, etc. No doubt an attempt to line the nest with material that keeps eggs from falling into the cracks.
