The osprey continue to add to their nest bringing in branches and other materials. They also have added some non-organic materials including what appears to be some cloth. Viewers from previous years who watched the Raptor Cam Red-tails will recall that the hawks incorporated a significant amount of human garbage into their nests. Osprey do the same thing. From a distance the nests typically appear to be all branches, but up-close you can see that it is interwoven with all kinds of other materials.
The birds have been at it since March 26th when they returned from migration--a full two weeks. This is pretty typical. They have also been going through their courtship rituals and copulating frequently. The female tends to stay on or close to the nest. The male collects most of the materials and also brings in fish to woo his mate.
Egg laying could begin at anytime. Osprey lay 1-4 eggs and it takes about 38 days to hatch. An osprey egg is slightly larger than a typical chicken egg. Once the eggs are laid, the female will do the vast majority of the incubation.
The following are some pictures of the osprey taken a few days back.
