Parker River National Wildlife Refuge was established in 1942 to provide feeding, resting, and nesting habitat for migratory birds. Located along the Atlantic Flyway on the Massachusetts coast, the Refuge is of special significance to waterfowl and shorebirds, including the federally threatened piping plover. Consisting of 4,662 acres (1,883 hectares) of diverse wetland and upland habitats, the Refuge also supports a great variety of mammals, reptiles, amphibians, insects and other wildlife.
Parker River Refuge is accessible by motor vehicle and foot over mostly gentle terrain. Several miles of foot trails meander through dune, shrub/thicket, freshwater marsh, and other Refuge habitats. Observation towers and platforms afford commanding views of the Refuge and surrounding lands and waters. A 6.3 mile (10.1 kilometer) roadway runs the length of the Refuge and provides several pull-offs. For your safety, roadside parking is prohibited and the 25 mph (40 kmph) speed limit is strictly enforced.
Wheelchair accessible birding sites include the Salt Pannes Wildlife Observation Area, the North Pool Overlook, the 0.3 mile (0.5 kilometer) Pines Trail, and the observation platforms overlooking the beach and ocean at parking lots 1 and 7.
Parker River Refuge is noted as one of the finest birding areas in the nation with more than 300 species recorded. While any season can produce a memorable visit, spring, summer, and fall offer the best birdwatching opportunities. Each season's highlights are described below.
Piping plovers first return in March to nest on the ocean beach. Purple martins begin to arrive in mid-April and are most easily observed from parking lots 1 and 4 at provided compartment houses. Raptor migration is best in April and early May with prime viewing available in parking lot 1. Top single-day flights of American kestrel, sharp-shinned hawk, and other species consist of several hundred birds. Peak migratory bird diversity occurs during the latter half of May. At this time a day's tally may result in one hundred or more species. Major waves of passerines, especially warblers, vireos, thrushes, and flycatchers, are the main attraction. Hellcat Wildlife Observation Area and the Pines Trail are popular viewing sites.
Good birding continues into early June with passerine migration still in progress. By early July, southbound shorebird migrants begin to arrive with numbers peaking in August. Viewing is normally best at the Salt Pannes Wildlife Observation Area at high tide and Stage Island, Bill Forward, and North Pools when water levels are low. Beginning in mid-August, large numbers of herons during some years congregate at Bill Forward Pool and other Refuge roost sites. In even greater concentrations, migrating tree swallows can be observed in marsh, beach, and other open habitats. Also at this time, warblers, vireos, and other fall passerine migrants become apparent.
Emerson Rocks (parking lot 7) attracts wintering loons, grebes, and sea ducks including common eider, white-winged scoter, and long-tailed duck. Also at this tidal area, purple sandpipers can sometimes be observed on exposed rocks. Two winter specialties are snowy owl and rough-legged hawk, found most commonly in Refuge grasslands and other open habitats. Northern shrike, another winter feature, is most frequently located in roadside trees and shrubs.
Please remain an unobtrusive observer by viewing birds and other wildlife from an appropriate distance and staying within designated public use areas.
During the warmer months, the Refuge sometimes fills to capacity and is subsequently closed for several hours. Arriving early may help you avoid this inconvenience.
This checklist provides information on the likelihood of seeing individual bird species through the seasons. This likelihood is based on the species' observability and is dependent upon many factors including its size, color, behavior, habitat preference, habitat conditions, relative abundance, and frequency of occurrence.
Prepared in accordance with the Seventh Edition of "The American Ornithologists' Union Check-list of North American Birds," this brochure lists 306 species which have been observed on or from the Plum Island section of Parker River National Wildlife Refuge. It also includes two separate lists of birds of extremely rare occurrence.

The probability of seeing a bird may vary within a season. The value assigned to each bird in this checklist represents the highest value that generally occurs within that season.
For specific information on Massachusetts birds concerning such factors as seasonal abundance, habitat preference, and early and late seasonal dates, refer to "Birds of Massachusetts" by Richard R. Veit and Wayne R. Petersen, and the "Field List of Essex County Birds," 7th edition, by by the Essex County Ornithological Club.

We are indebted to the many visiting ornithologists and birders who have over the years contributed significantly to the Refuge avian data base. The accuracy of future checklists depends in part upon the continued support of such professional and amateur bird enthusiasts. Please report significant observations to Refuge Headquarters at the address or phone number listed at the end of this brochure.
