Notes There was almost no wind when we started but an hour later it picked up to Beaufort Wind Scale Level 2 (6-11 km/h). It was extremely hazy making finding birds extremely difficult especially when we were looking south and ridges were backlit. Clear visibility was barely a mile. There was no ice at all on the Hudson River. Ponds and lakes had some ice.
