Earliest Peregrine Falcon Nest in N.Y.C.?

Image above taken on 24-Apr-2006 — Peregrine Falcon perched near possible nest site on G.M. Building's north face.

The following article on Peregrine Falcons points out that the "first known nesting in New York City occurred in 1943 when a pair successfully hatched three young on a coping of the St. Regis Hotel".

Below is an image I took tonight of the site mentioned in the article. The St. Regis Hotel is on 5th Avenue and 55th St. on Manhattan.
