In the Sanctuaries …

March 16, 2021 — The focus of attention at the Milford Point Coastal Center last week was the yellow leg-wear of a visitor to the outer sandbar.

The visitor was an American Oystercatcher, banded with a yellow leg identification tag. Bird banding is a long-established method for tracking the movements of migratory birds. Each time a bird with a band is observed, and the observation recorded with the U.S. Geological Survey, a data point is added to the record.

Connecticut’s coasts and the nearby waters of Long Island Sound are globally important for migratory shorebirds and waterfowl. In this case, the arrival of one bird, though seemingly inconsequential, reconfirmed Milford Point’s importance as a place for migratory shorebirds to rest and feed.

Katerina Gillis, who works for Connecticut Audubon as the IBA coastal ranger at Milford Point, snapped this photograph on March 12, from about 150 feet away.

Milford Point is among the best places in the northeast to look for migratory shorebirds, and we encourage you to visit on your own or sign up for our bird walks.

August 2, 2020 — Empty nest syndrome: the Purple Martins have fledged.

Each week, Frank Mantlik, a member of the Coastal Center’s regional board, has led a team that checks each of the gourds at the Coastal Center colony. Here’s his latest report:

On Thursday, July 30, I was joined by staffers Stefan Martin and Kat Gillis, volunteers (and fellow Board members) Lori Romick, George Amato, Gilles Carter, and intern Liam Hourihan to conduct our eleventh nest check of the season of the Milford Coastal Center’s Purple Martin colony.

It was a typical summer day: sunny, hot, 86F, humid (53%), with a warm SSW breeze at 10 mph. While prepping for the survey, we counted about 20 adult Purple Martins actively bringing food to their chicks. Several of the remaining chicks were peering out of the nest holes. Undoubtedly more chicks have fledged since last week.

Conducting the survey, many nests that had chicks were now empty [you can read an earlier report of Frank’s, from mid-July, when the nests were more active]. Many Martin youngsters have fledged. In fact, while we worked, three more took their first flights! Wings, don’t fail me now! The one that flew from #57 was caught and returned to a healthier nest in #60. Unfortunately, we found single dead chicks in three different gourds; cause of death unknown.

Of the 71 total gourds, only 8 still have chicks. The two remaining eggs have not hatched and are deemed unviable. About three gourds still had an issue with some mites, and we wiped the excess.

Gourd # 38 with the nest-cam is now empty, with those chicks having fledged as of 7/24. Our very efficient crew completed the work in just 30 minutes, minimizing disturbance.

An Hour Spent Tagging Monarchs

by Tom Andersen, Communications Director
September 30, 2019 – Last week Carol Kratzman, the teacher-naturalist at the Coastal Center, told me she would be tagging monarch butterflies in a couple of days and invited me to come along.

I thought it would make a good story so I emailed Jill Dion, the editor of Hearst’s Milford Mirror. She responded with a quick “Thanks Tom.” When I got to the Coastal Center around noon on Thursday, Jill wasn’t there but photographer Brian Pounds of the Connecticut Post/Hearst was.

He told me they had already caught and tagged one monarch.

I was prepared to take notes but Carol handed me a butterfly net instead. We searched the pollinator garden: a couple of monarchs, a painted lady, a common buckeye. I watched Carol’s technique. When she found a monarch feeding on a flower, she simply dropped the net over it. Then she grabbed the toe end of the net and pulled up, which gave the butterfly room to let go of the flower. Then she lightly grabbed the net below the butterfly with her other hand and carried it to a nearby bench.

She had a clipboard and an envelope with tiny round adhesive tags, like tiny name tags for a party. Like the leg bands that bird banders affix to birds, each had an identifying number. Her technique was to lift a side of the tag and slip the tip of a toothpick under it, like a miniature flag on a miniature flag pole, then lift.

She took the butterfly out of the net and asked me to apply the tag. I told her that my manual dexterity was poor. “It’s easier that you think,” she said. She gently held the butterfly so the back of one wing was facing me. She touched a spot on the wing and directed me to place the tag there. I did, and I rolled the toothpick out from under it. Then we freed it. She entered the data on a sheet of paper, so she could send it later to Monarch Watch. If someone finds the butterfly and reports the number on the tag to Monarch Watch, the information gets entered into a database to help track the migration route of this vulnerable species.

Melina Giantomidis, Connecticut Audubon’s Osprey Nation coordinator, showed up. We invited her to help. The four of us walked out to the dunes, where it was hot and breezy. Carol told us to look for monarchs in the goldenrod and then catch them. I felt guilty about walking through the dunes, but I trod lightly. Monarchs were, if not quite abundant, than at least common. We easily caught and tagged eight.

The Connecticut Post published Brian Pounds’s photos with a short accompanying article.

Other Species

A total of 315 bird species have been seen at the Coastal Center. Ospreys nest in the marsh. Highly vulnerable species such as Piping Plovers and American Oystercatchers nest on the beaches. Snowy Owls often spend the winter in the area. Thousands of shorebirds congregate in August and September.

The nearby waters of Long Island Sound and the Housatonic River are rich in oysters and clams. The dune habitat supports rare plants. A thriving population of Purple Martins occupies a colony at the edge of the marsh.

Four observation platforms are available to wildlife viewing, as are the beaches. We also have a newly-established pollinator garden. We ask visitors to keep a respectful distance from all wildlife.
