Day 254: September 10 – Bear Mt. Hawk Watch


Sunny and cool (low 70s) with a light NW breeze

       Each year for the past decade or more, a loyal group of dedicated birders ascend to the top of Bear Mountain to take part in the annual hawk watch.  This is not a one day  affair.  In fact, it is a daily venture beginning on Labor Day weekend and continuing all the way through Thanksgiving.   Our leader Joe S. has been at the helm for many years now and continues to be the mainstay of the project. 


       We are following and documenting the fall migration of hawks, vultures, ospreys, falcons and eagles as they move south down past the Hudson Highlands.  We keep tallies of what species are seen and how many of each pass us each day.  Each member of the group will show up whenever he or she can to assist with the count.  At times, there may be 15 or more folks taking part, and at other times, it’s just Joe.  Spotting scopes, binoculars, cameras and computers all are valuable tools.  When the year’s count comes to an end, the data will be sent to Cornell University’s Lab of Ornithology where it will be added to the counts done by other volunteer groups across the eastern seaboard.

       Each week brings a new group of migrants through the valley.  Right now, we are on the leading edge, so it is primarily Bald eagles, Red-tailed hawks, and an occasional hawk of other species that wanders on through.  Soon, however, the first wave of massive migratory movement begins with the Broad-shouldered hawks making an appearance.  We are about a week and a half away from the expected “flood” of these birds.  One they about Mother Nature…..you can never say “always”.  There are trends, and these are when the birds are expected.  But they don’t always read the books, and they may show up earlier or later than expected, or they could take a different route this year and not show up at all!  But this is why we are there. When all is said and done, the powers that be will have a better idea of where and when the raptors migrated this year.  We’ll just have to wait and see how it plays out.

      After our day’s watch today, we had only several birds….two Bald eagles, two Red-tailed hawks, one Osprey, and a Northern harrier which flew south past our vantage point.

       As we headed back down off the mountain, we ran across several white-tailed deer who approached our vehicles as if conducting their own inventory of how many humans passed through their territory. 


       We’ll be back later this week to help out once again and hopefully begin to see more and more of the travelling birds heading south.
