320 Park Ave.
These observations occured while heading back to work as I passed through the Park Ave. Peregrine Falcon territory. As soon as I turned the corner I spotted a falcon on 320 Park Ave. (Mutual of America Building).
The image to the right was taken on March 28th and is the exact same perch I found this Peregrine on. It was facing south and keeping an eye on the nest building. This falcon was first spotted at 6:10pm EDT.
At 6:35pm I decided to move north from the Waldorf-Astoria Hotel, where the President was just arriving, to my usual viewing spot at 52nd St. and Park Ave.
From here I spotted an object in one of the openings on the north face of the nest building. Since I didn't have binoculars I could only guess this was a Peregrine Falcon. It was the right size, the right color and had the right attitude.
