Broad-winged Hawk Flights Underway

The smoke has cleared—at least for now—and Broad-winged Hawks are being seen migrating across lower Susquehanna valley skies.  Check out these daily counts from area hawk watches…

    • Rocky Ridge County Park Hawk Watch northeast of York, Pennsylvania: 475 Broad-winged Hawks on Saturday, September 18th—including 388 during the two hours between noon and 2 P.M.
    • Second Mountain Hawk Watch at Fort Indiantown Gap in Lebanon County, Pennsylvania: 300 Broad-winged Hawks on Wednesday, September 15th— one more than was tallied passing the site on the previous day.

Additional Broad-winged Hawks are still working their way through the Mid-Atlantic States as they continue toward tropical wintering grounds.  And there’s more.  Numbers for a dozen other migratory hawk, eagle, and falcon species will peak between now and mid-November.  Days following passage of a cold front are generally best—so do get out there and have a look!
