These skyscraper nests dot the coastline throughout the North Fork and the return of the Osprey is the true mark of Spring. Migrating from South America, the male Osprey makes the long journey home returning to his nest from the previous season. He'll spend the next few weeks sprucing it up for his female companion who arrives later. Some "unattached" females arrive to scope out the tonyiest nests; the males who occupy them, well, they're secondary. Keep an eye out for one such nest reported to be 10 feet tall and 125 years old.
