Keep Calm and Bird On: March 2024

March 1, 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.

Margaret Harwood

By Jascin N. Leonardo Finger • July 21, 2025
The MMA found its first astronomer in Margaret Harwood, a 1907 Radcliffe graduate who worked in the Harvard Observatory. Her fellowship began in 1912 and over the first year, she researched, continued to conduct public lectures and open nights, and worked with students of all ages – including those in the public schools. She returned to Cambridge for the winter months where she continued to work at the Observatory. In 1915, she took her leave as was authorized by the fellowship and acquired her master’s degree in astronomy at Berkeley. She returned to Nantucket in 1916, accepting the position of Director of the Observatory. This made Harwood the first woman to head a small private observatory in the United States. Harwood continued her research, with a focus on variable asteroids, published results of her work in numerous publications, and continued to lecture and host open nights. She had assistance from others, including island carpenter and school teacher, Alvin E. Paddock. Harwood became a “first –class celestial photographer . . . accumulating a valuable set of Nantucket photographic plates of variable stars . . .” which are still part of the MMA collection and were the first in the world to be completely digitized. Over the course of her tenure, more than 3,600 plates of the night sky were taken – more than 2,100 by Harwood herself. In the 1950s, Harwood was the first woman to gain access to the Mount Wilson Observatory then the world’s leading observatory, where she was able to use the photographic instruments to further her research. Harwood is seen in the photograph here as she looks for Venus during midday in the MMO using the Cooke-Clark telescope, guided by Maria Mitchell’s own Alvan Clark. JNLF

Nantucket Maria Mitchell Association Welcomes Kike Calvo as Featured July Presenter.

July 14, 2025
NANTUCKET, MA— The Nantucket Maria Mitchell Association (MMA) announces Kike Calvo, award-winning photographer, journalist, and author, as its featured presenter for its July Speaker Series. Calvo’s presentation, "The Power of Creativity: A Journey Through Storytelling, Exploration, and Hope," will take place on Wednesday, July 23 at 7pm at the Nantucket Atheneum’s Great Hall. This event is free. Join the MMA for an engaging evening with award-winning photographer, journalist, and author, Kike (Kee-Keh) Calvo. A Fellow of both the Explorers Club and the Royal Geographical Society, he has traveled to over 120 countries, photographing everything from belugas in the Arctic to traditional dances in Vanuatu. His work has been featured in National Geographic Magazine, The New York Times, Rolling Stone, and more. In this engaging presentation, Calvo explores how creativity can be a catalyst for connection, storytelling, and meaningful change. From documenting remote villages to diving with great white sharks, from defying the odds as an author to inspiring thousands of children in the Amazon, Calvo shares the invaluable lessons he has learned along the way. As a National Geographic Certified Educator and Safina Center Fellow (2020-2023), Calvo combines his passion for photography with teaching, having lectured at prestigious institutions such as Yale University. A pioneer in drone photography for art and conservation, he founded the “Little Explorer, Big World” initiative, which brings education to remote communities and has donated over 35,000 bilingual books. Described by anthropologist Wade Davis as, "a fresh voice in visual anthropology," Calvo has a gift for capturing the intersections of human existence. Calvo’s new book, Luminous: A Field Guide for Visual Explorers and Storytellers, isn’t just a book—it’s an invitation to slow down, look deeper, and photograph with soul. It’s a roadmap where photography meets presence, anthropology meets art, and storytelling becomes a path to connection.  Discover how creativity can illuminate pressing global issues—such as plastic pollution—and empower each of us to make a difference. This presentation is free and open to the public, graciously hosted for the MMA by the Nantucket Atheneum in the Great Hall. No registration required. About the Maria Mitchell Association: 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. ###
