Keep Calm and Bird On: April 2024

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

There will be a partial eclipse of the Sun on Monday April 8, beginning at 2:17 p.m. and returning to full daylight at 4:39p.m. Even though a partial eclipse may not look so dramatic to us, chances are birds experience it more intensely. They see further into the ultraviolet end of the spectrum than we do, thanks to an extra set of cone cells in their eyes. We have only three types; birds have four. They can also see polarized light, and the earth's magnetic field. So they may exhibit unusual activity, even if it is a cloudy day.

 

We don't have a lot of information about the effects of unexpected (by avian standards) events such as eclipses on birds. During an eclipse, our natural tendency is to want to look at the Sun. (Don't do it without protective glasses! It could permanently damage your vision.) But in order to learn more about how an eclipse can affect our avian friends, start now by making baseline observations of birds at home or in a favorite birding spot in the days before the eclipse for comparison purposes. A few days will give an idea of what a normal afternoon at the crucial time looks like.

 

On the eclipse day, watch or feed at the usual times. Start about ten or fifteen minutes before the eclipse will begin. Try to give at least ten minutes per observation, and make a schedule of times you plan to bird. You can take breaks, as long as they are consistent. Then, see what happens as darkness begins to fall. Do birds become agitated? More vocal? More aggressive? Less? Confused? Is there any change at all? Do they change as it becomes lighter again? How fast do things return to normal? Your observations can help us understand how wild birds see, sense, and respond to novel situations.

Yes. Well, almost. After about a month of working – and some living (staff and or neighbors) – on Vestal Street with all the sewer and water replacement work, the paving happened today (April 17, 2024). This is the first “layer” – a three-inch binder coat. In the fall, once time has passed, they will return for the final one inch of the finish layer. Some of the other things along Vestal Street will also be repaired and updated between now and the final coat – and a bit after that. But we are very happy, after all these years to have a modern system of piping – and all new drainage we never had before! While the curator in me loved the old clay pipes, they were riddled with roots from the trees, holes, and in some places, collapsed, and the twelve inches of asphalt had to go. Vestal Street was only paved in about 1946/1948 – and has not been paved in maybe twenty years so that is a lot of asphalt in about fifty years! And with climate change and the increase in how much rain we get in these heavy rain events, all that water rushed down Vestal Street with nowhere to go – except our cellars. I am sure the neighbors are happy too! A thank you to the Town of Nantucket’s Sewer Department, especially David Gray (who may regret giving me his cellphone number forever), N&M Excavating and Utilities (Dean, we appreciate you being so nice when we had too many questions), Victor-Brandon Corp for paving, and numerous others. We are looking forward to great flushing, powerful hose lines, and rainwater being whisked away via the new, never-before-had storm drains! JNLF And to all the N&M workers who wondered why I was constantly looking down as I walked along Vestal Street, you should see the trove of porcelain shards, glass, old nails, a bottle neck, 19 th century spoon, and even possibly a Wampanoag stone tool I found!

Vestal Street has seen a bevy of activity of late. In January, we began the renovation of the Maria Mitchell Vestal Street Observatory’s (MMO) Seminar Room addition – as it has been referred to since it was built in 1987. When it was created, the point was for it to serve as meeting, lecture, work space on three floors for the Astronomy Department – in particular the National Science Foundation Research Experiences for Undergraduate (NSF REU) interns we have each summer, visiting astronomers, and the astronomy staff. Believe it or not, it was the first time the Observatory had a bathroom! And, it connected to what we refer to as the Astronomer’s Cottage (ca. 1830 and purchased for the MMA in 1922) so that staff could move between the house and the Observatory without going outside – convenient! With a gift from board member and Mitchell family descendant, Richard Wolfe, we have been able to renovate this space, bringing it up to date and adding HVAC, an accessible bathroom and kitchenette, three office spaces, a seminar/meeting area, and space for intern workspaces. Lighting and interiors are being improved as this is written and we hope to have the space ready by June 1, 2024. A special thank you goes to John Wise, another Board member, who has been working with the MMA to make sure this renovation happens in a short timeframe. The work here dovetails nicely with the conservation of the historic observatory to which the Seminar Room is connected. The historic MMO, built in 1908 with a 1922 addition, has seen exterior conservation work over the last several years with support from the Community Preservation Act and the M. S. Worthington Foundation. This fall, we will move inside with more grant funding which will allow us to conserve the historic interiors and install a proper HVAC system to protect the historic fabric and historic astronomical equipment and papers. We will restore the floor in the Astronomical Study from 1922 – it’s hidden under wall-to-wall carpet and 1950s tile but it’s still there – and allow us to conserved the historic plaster and all of the original varnished woodwork. Stay tuned on this project. JNLF

To me, Nantucket was always tumbledown fences. Covered in lichens, worn with wind and salt spray – grooved even – and a deep grey. Pieces broken, swinging in the wind as this broken one was with the 50mph gusts. Held together by vines – ivy or rambling climber vines, or honeysuckle. You do not see as many nowadays. This one is in town along a lane – possibly older than the house it wraps around as there was once a much older house there in the 1950s/1960s. Taken down to make room for this one – in a not so kosher manner – but that’s a story for another day. The lichens and mosses that grow on them, the vines that cover them, provide food and shade and coverage for a myriad of life – from the tiniest insects to small birds hiding from red-tailed hawks or even people and cats. Architecturally they speak of our past. While this one is very simple and not as old as others, it hearkens to a time in which cars were fewer, the island was quieter, and life was simpler. A fix was one picket not a whole fence. And some of the much. much older fences make me think of Maria Mitchell and her day when there were a lot of fences too – but not to keep people out or to create a “privacy screen.” They were there to keep animals in the yard – and more often to keep wandering animals OUT of the yard.
