Keep Calm and Bird On: March 2024

“If you don’t look, you don’t see. You have to go and look.”
-Edith Andrews

The fact is, we never know what may show up in the winter. Look closely and you can see the unmistakable head of an-out-of season Whimbrel in the icy marsh. A young bird taking a late jaunt found the UMass Field Station marsh a welcome rest stop for almost a month.

In March what we look forward to most is the Ospreys’ return. Usually around the 23rd or 24th, sometimes a little sooner, sometimes a little later, these magnificent birds are coming back to the old roost, to the old nest, to familiar fishing grounds.


Their stick nests atop high platforms sometimes attract Red-tailed Hawks, however. All through February Red-tails have been pairing up, looking at old nests, exploring the potential of new ones. And sometimes an Osprey nest of a previous year looks like the perfect Red-Tailed starter home. At least, until an Osprey shows up. Battles between the two can be dramatic. Both are equipped with razor-like, skin-tearing beaks and sharp, hooked talons. Both are territorial. But the Osprey out-weighs the Red-tail by about a pound, with an extra foot or so of wing-span, and perhaps most important of all, attitude. Red-tails are a bit more lackadaisical. Rather than diving into cold water searching for shadows of a fish dinner, they often hang out along highways, waiting for dinner, often in the form of roadkill rabbit, to be delivered. So in a contest over a nest, the Osprey usually wins.


Then it is the Ospreys’ turn to go through the ritual of courtship and nest-building. Will it be the same mate? Did he or she survive the hazards of the long journey to South America and back? Successful pairs often continue together. If both survived the trip, if they liked the location, if they raised two or three young together, it’s likely to be “don’t mess with success.” That’s a lot of ‘ifs.’ And sometimes there is disappointment. But, is there someone else hanging around? A better provider, stronger, or more determined? Or just lucky with the timing of a favorite food? Ospreys do best when there is a bountiful herring run. This early-returning, oily fish is packed with nutrition for developing eggs, and later, for growing young. So the drama continues.

The MMA, NLC, and SN will be offering fun daily events from Monday, August 3 to Saturday, August 8 to learn about, and take action against, invasive European green crabs on Nantucket. European green crabs were first introduced to North America in the 1800s, likely traveling in the ballast water of merchant ships from Europe. This invasive species is now abundant on Nantucket, threatening crucial aquatic resources, including eelgrass beds, shellfish populations, and native crab communities. Together, as a community, it is possible to help prevent green crabs from destroying the natural resources that make Nantucket’s waters so special! Please come join us during Nantucket Green Crab Week to learn more.

Sustainable Nantucket is a nonprofit organization dedicated to strengthening Nantucket’s local food system and building a more sustainable island community. Through education, advocacy, and community programs, the organization supports local farmers and producers, increases access to locally grown food, and connects the community with Nantucket’s agricultural resources. The Nantucket Land & Water Council is a nonprofit organization dedicated to protecting Nantucket’s land, water, and natural resources. Through conservation, research, education, and advocacy, the organization works to preserve open spaces, protect water quality, and ensure the long-term environmental health of Nantucket for future generations. The Maria Mitchell Association was founded in 1902 to preserve the legacy of Nantucket native astronomer, naturalist, librarian, and educator, Maria Mitchell. After she discovered a comet in 1847, Mitchell’s international fame led to many achievements and awards, including an appointment as the first professor of astronomy at Vassar College. Maria Mitchell believed in “learning by doing” and today that philosophy is reflected in the MMA’s mission statement, programs, research projects, and other activities. The Maria Mitchell Association operates two observatories, a natural science museum, an aquarium, a research center, and preserves the historic birthplace of Maria Mitchell. A wide variety of science and history-related programming is offered throughout the year for people of all ages. ####
