Words On Birds by Steve Grinley

Rare Hawk Continues to Show

     The Swainson’s hawk is a raptor of the open fields and prairies of the central and western regions of the country and a rare visitor to New England. It is a member of the buteo family – large hawks with short tails. Our common buteo is the red-tailed hawk, but the Swainson’s is noticeably slimmer. The light morph is light underneath with a dark chest giving it a hooded appearance. The dark trailing edges of its flight feathers is distinctive and wings appear more pointed in flight.

    One is sometimes spotted here, usually in fall during migration. But this year, a Swainson’s hawk has taken a liking to Essex County’s Great Marsh this winter. It was first spotted late one day in January on Sandy Point, Plum Island by Miles Brengle and Nate Dubrow. They viewed the bird with spotting scopes from across the sound on Great Neck in Ipswich!
 
     The rare hawk remained overnight and was seen early the next morning by birders on Plum Island. After a very short time, the Swainson’s hawk took flight south and disappeared.
 
     It wasn’t until February that this bird was rediscovered hunting the marshes of Good Harbor Beach in Gloucester. The bird stayed for several weeks and birders from all over the state, and beyond, came to see this rare visitor. Many bird clubs from Western Mass, Connecticut, New York and New Jersey visit Essex County annually in mid-February for its winter birds. They all got a bonus this year with the mostly cooperative Swainson’s hawk, rare to the Northeast.
 
     The hawk disappeared again in early March, presumably finally heading home? Or so people thought. Until this past Tuesday, April 1st, when the Plum Island hawk watchers saw a Swainson’s hawk heading north at 12:30pm. 
 
     Margo and I arrived on Plum Island after 2pm and we stopped at parking lot 1 to congratulate the hawk watchers.  We got back to our car and we were about to drive down the island when Margo exclaimed “look at that bird!” A hawk was circling just southeast of the parking lot and a quick look with the binoculars confirmed it was the Swainson’s hawk! I turned toward the platform to alert the hawk watcher’s but they were already on it.
 
     Margo was busy with her camera, trying to get photos of the bird as it circled above, against the sun. It finally caught the wind and drifted south, out of sight once again. Following the excitement, we headed down the island and encountered the Swainson’s hawk once again over parking lot 2. We posted an alert that the bird was heading north once again.
 
     Photos confirmed that this was the same bird that Miles and Nate found back in January. And the same bird that spent weeks at Good Harbor Beach. It returned to Plum Island and may choose to spend some more time here. It might join the hawk migration northward into New Hampshire or it may finally head west to its native territory.
 
     The Plum Island hawk watchers did have a good hawk flight that day as well, tallying 135 kestrel, 10 merlin, 7 northern harriers and 9 turkey vultures.
 
     So when visiting Plum Island, or any open area along the coast, keep an eye out migrating hawks, and, especially, for the Swainson’s hawk. He may still be around!
