Super windy and chilly Saturday afternoon but nonetheless beautiful. I renewed our annual Parker River National Wildlife Refuge pass, which is good for one year, and think it is the best twenty dollars spent. Kudos for being the cutest pass, too!
What fun to encounter a small flock of terns teaching its young to fish. Nearly as large as the adults, the tubby terns cheekily squawk and demand food (shrimp I think in this case). Watch as the fledglings try to master fishing skills while the adults tirelessly guide the young on how to feed themselves.
There is nothing common about the uncommon Common Tern. They were named Common because hundreds of thousands formerly nested along the Atlantic Coast. As with many species of shorebirds, the rage for wearing fancy feathered hats during the 1800s nearly drove these exquisite “swallows of the sea” to extinction. After the Migratory Bird Treaty Act was ratified in 1918, terns began to recover.
A second major setback occurred when in the 1970s open landfills were closed, displacing thousands of Herring and Great Black-backed Gulls. The aggressive and highly adaptable gulls resettled to offshore nesting sites used by terns.
Common Terns are a Species of Special Concern in Massachusetts. Through a statewide long-term commitment of restoration, protection, and management of nesting colonies, the populations are very slowly and gradually increasing.
Former nesting sites include islands such as Cape Ann’s Thacher Island. During the mid 1950s, over 1,125 pairs of Arctic, Common, and Roseate Terns nested on Thacher Island. Today there are none.
The southern side of Thacher Island is owned by the Thacher Island Association. The northern end of Thacher Island is owned by the U.S. Fish and Wildlife Service, under the authority of the Parker River National Wildlife Refuge. These organizations are working together to restore terns and other species of birds to Thacher Island.
I am in the midst of doing research for the Piping Plover film project and have found the Parker River National Wildlife Refuge to be a great resource. Recently I met a terrific warden there, Jean, and she gave me a copy of the historic brochure written in 1947 by Rachel Carson about the refuge. The brochure was reprinted and if you inquire, they may still have some copies in the back office. You can also download the brochure at this link: Rachel Carson Parker River Wildlife Refuge brochure
The brochure provides an early history of the refuge and is a fascinating view of mid-century conservation. And, too, it is a tremendous example of Carson’s thoughtful and thought-provoking style of writing.
Some interesting facts about the refuge —
Located along the northeastern coast of Massachusetts, the Parker River National Refuge includes lands that lie within the three towns of Rowley, Ipswich, and Newbury. We think of Plum Island as the heart of the refuge. The wildlife refuge also includes a range of diverse habitats and geographic features; over 3,000 acres of salt marsh, freshwater marsh, shrub lands, a drumlin, cranberry bog, salt pannes, beach and sand dunes, and maritime forest. The land is not conserved to revert back to a wild state, but is intensely managed in order to preserve and maintain the diversity of wildlife habitats.
Unlike our national parks, which preserves parklands or historic buildings, and are designed for people, a national wildlife refuge is established first and foremost for wildlife and their habitats, not for people. The preservation of wildlife is the number one priority of all our national wildlife refuges.
The Parker River National Wildlife Refuge was established in 1942 to help species of waterfowl that migrate along the Atlantic Flyway. There were three sharp declines in waterfowl populations in the early half of the 20th century, notably the American Black Duck, and national wildlife refuges all along the Atlantic coast were created in response to the precipitously low numbers.
As we can see with our local Niles Pond, Henry’s Pond, and Langsford Pond shorebirds, waterfowl, and myriad species of wildlife thrive where they have easy access to both fresh water and salt water. The three bodies of fresh water that you see in the refuge look like ponds but they are actually manmade impoundments, created by dams and are highly controlled by a series of dykes and pumps.
Parker River provides pristine habitats for a wide variety of mammals, insects, fish, reptiles, and amphibians. Hunting birds such as owls, hawks, osprey, eagles, herons, and egrets find an abundance of food at the wildlife refuge. Whenever at Parker River I never not see a raptor!

Transfixing Owl Eyes
Because owls mostly hunt at night their eyes are very efficient at collecting and processing light. To protect their extraordinary eyes, owls are equipped with three eye lids; an upper and lower lid, and a third lid that diagonally closes across the eye. This action cleans and protects the eye.
