Question: Where should I look on the Gulf Tower to see the peregrines?
Answer: The Downtown peregrines spend time at the Gulf Tower throughout the year but don't necessarily use the site for their nest. They nested here from 1991-2011 and again in 2014 and 2017. In 2012, 2013, 2015 and 2016 they nested elsewhere Downtown.
When the peregrines are at the Gulf Tower they usually visible on the falconcam. To see them from the ground, look in the area indicated on the north face of the Gulf Tower. The best place to stand is at the railroad station (Penn Station) or the Greyhound station parking garage roof.
