Bedford Audubon’s 2017 Chestnut Ridge HawkWatch ran from August 25 through November 22, spanning 90 days. The count was held 84 days, totaling 589 hours, with 6 inclement weather days.
Mid-September was very warm with average high temperatures over 25 C; unseasonably warm temperatures persisted through late October. November 11 was the coldest day, with a high temperature of 2 C. Three Atlantic hurricanes, the season’s Atlantic hurricanes: Irma and Maria in September and Nate in early October, likely impacted migration.
The grand total of migrating raptors counted at Chestnut Ridge in 2017 was 9,007, almost 3,000 below the 14-year average of 11,986. This is probably due to the relative low number of Broad-winged Hawks this season.
