I watched both the male and female make sorties into the park, snipping off branches with their powerful beaks.
To date, I have not witnessed any copulation, and last years eggs were laid around March 14th. That still gives us a few weeks of time for the Cathedral to make their repairs. If anyone has a contact at the Cathedral, maybe we can petition for them to begin the work on that part of the Chapel.
Up on Riverside, the same problem exists.
Both species show a lot of tolerance for human activity, but we've seen it before in numerous cases, notably the 5th Ave. red-tailed hawks--Pale Male and Lola--but also in others, where human presence can disrupt nests. The GM peregrines are another notable situation where the installation of the spotlights for the new Apple Store disrupted the nesting peregines. All in all, New York City has many successfully nesting raptors that all have to contend with human interference at one time or another. Hopefully we can find a balance between the needs of our institutions and places of business and the rhythms of the natural world.
