In winter, Northern harrier
hunt in the grasslands.
Ironically, the only male Northern Harrier
(marsh hawk) I have ever seen was teetering above the taxiways near Terminal C at EWR!
During breeding season, a large assortment of species nest on the area, including waterfowl--such as mallard and wood duck, and several state-listed species, including least bittern (threatened), pied-billed grebe (threatened), American bittern (special concern), northern harrier
(threatened), and sedge wren (threatened).

For species recorded from transects (northern harrier
, horned lark, Sprague's pipit, vesper sparrow, and meadowlarks), we used maximum number of individuals of that species recorded during a season on each transect, summed across all transects for an index of relative abundance (=total number of individuals) per site per year (Johnson, 2008).
Two small predator species (American robin and Brewer's blackbird), four large known predator species (osprey, bald eagle, sandhill crane, and great blue heron), and four large suspected predators (red-tailed hawk, northern harrier
, common crow, and ring-billed gull) were encountered during the surveys.
Featured are the northern goshawk, peregrine falcon, golden eagle, osprey and northern harrier
. According to the Cascades Raptor Center in Eugene, all five species live in the area.

, an American version of our hen harrier, is currently wintering on the saltmarsh near Thornham.

Rail transmitters were recovered from unusual locations, including the nest of a northern harrier
(Circus cyaneus), under several inches of soil (where it was presumably buried by a fox), and at a feeding station for a feral cat along the bay shoreline.
