I heard Flaco early in the evening hooting from near 565 West End Avenue, but couldn’t find him. I explored the neighborhood but didn’t find him and decided to check out other location he’s been visiting and get dinner. I then retuned to West End Avenue and found him on 250 West 90th Street. He hooted for about twenty minutes before he flew to a building at 91st and Riverside before flying south. I couldn’t relocate him.
