I'm a little late to the party, since these Peregrines have been on The Century for three years. But I was overjoyed to see the parents and their two eyasses on Saturday. The Century is located at 25 Central Park West between 62nd and 63rd Streets.
The nest box is on the eastern side of the south tower. For news about the hatching of the two eyasses, see The West Side Rag and the Gothamist.
(I am concerned about a picture in The West Side Rag. The pebbles in the nest box are much larger than the gravel traditionally used in nest boxes. Given that only two of four eggs hatched this year, the owners of the box might want to switch to a gravel approved for nest box use before next season.)
