Beautiful but fleeting surprise spring sighting at Bass Rocks this weekend- a male Red-winged Blackbird collecting cattail fluff for nest building, and two species of herons foraging, a Great Egret and Black-crowned Night Heron. Oh Joyous Spring!
Jeff Denoncour, the Trustees of Reservations Eastern Region Ecologist, gave an outstanding and informative presentation to a packed audience Saturday afternoon. Subjects included the formation and history of Crane Beach, marsh, and dunes; the seven uniquely different ecological zones; the many species of flora and fauna that comprise the rich biodiversity at Castle Island; and the Trustees protective measures managing rare and endangered species.
Since 2010, Jeff has managed the Trustees Shorebird Protection Program at Crane Beach. Because of the very excellent shorebird management at Crane Beach, 2018 was a banner year, with 42 pairs of nesting Piping Plovers and approximately one hundred PiPl chicks fledged. Our community can learn a great deal from the success at Crane Beach in how to better manage shorebirds migrating and nesting at Cape Ann beaches.
We learned from Jeff that Crane Beach is part of a string of barrier beaches formed from sediment deposited by the outflow of the Merricmack River. Salisbury Beach is at the northern end, then Plum Island, then Crane, with Coffins and Wingaersheek at the southern end. The sand that was deposited at Salisbury Beach is the coarsest; the sand at Wingaersheek the lightest and finest as it would have more easily flowed furthest away from the mouth of the river.
Excerpt from a previous post OUTSTANDING COASTAL WATERBIRD CONSERVATION COOPERATORS MEETING! talking about Jeff and the success of the Crane Beach Trustees Piping Plover
“Readers will be interested to know that our region’s Crane Beach continues to have one of their best year’s ever. Trustees of Reservations Jeff Denoncour shared information on the latest census data from 2018 and Crane Beach has a whopping 76 fledglings, with 25 more chicks still yet to fledge. Because of the huge success at Crane Beach, the northeast region, of which we are a part, has fledged a total 136 of chicks in 2018, compared to 108 in 2017, and as I said, with more fledglings still to come! The northeast region encompasses Salisbury Beach to the Boston Harbor Islands.
Jeff noted that this year they had less predation by Great Horned Owls. Because of owl predation, several years ago the Trustees gave up on the wire exclosures and now use electric fencing extensively. The Great Horned Owls learned that the Piping Plover adults were going in and out of the exclosures and began perching on the edge of the wire, picking off the adults as they were entering and exiting the exclosure.
Crane has an excellent crew of Trustees staff monitoring the Least Terns and Piping Plovers, as well as excellent enforcement by highly trained police officers. No dogs are allowed on Crane Beach during nesting season and dogs are prevented from entering at the guarded gate. As we saw from one of the graphics presented about nesting Double-crested Cormorants, when a dog runs through a nesting area, the adults leave the nest, temporarily leaving the eggs and chicks vulnerable to predation by crows, gulls, raptors, and owls.”
Both kinds 🙂
Click the photos to make larger and you can see the fine ribbon of migrating birds. Many, many species of birds migrate at night. You can often see them very late in the day as they are beginning their night time journey, traveling along the shores of Cape Ann before crossing Massachusetts Bay on their southward migration.
The Great Egret doing the happy dance was fishing with a group of mixed herons and egrets when he began to leap about and flourish his wings. I couldn’t tell why from the distance I was shooting until returning to my office to look at the photos and saw he had a minnow in his mouth. What a show-off!
What is happening here? A hungry swim of cormorants have pushed a stream of bait fish towards the shallow shore waters. The minnows are met by equally as hungry Snowy Egrets and Great Egrets waiting on the rocks. I’ve watched many egrets eat prey and they often toss it about in the air for half a minute before swallowing whole, I think to line it up so the fish or frog goes straight down its gullet. At that very moment when the egrets are adjusting their catch, the gulls swoop in and try to snatch the minnows from the egrets.
Great Egret Flying Over Perched Osprey
There is much to chortle about in this latest Cape Ann Winged Creature Update. Early April marked the arrival of both Snowy and Great Egrets, Black-crowned Night Herons and Great Blue Herons. Osprey pairs and evidence of Osprey nest building can be seen wherever Essex Greenbelt platforms have been installed. Northern Pintail and American Wigeon Ducks are stopping over at our local ponds on their northward migrations while scrub and shrub are alive with the vibrant song of love birds singing their mating calls. Oh Happy Spring!

My husband Tom suggested that I write a year-end post about the wildlife that I had photographed around Cape Ann. Super idea I thought, that will be fun and easy. Not realizing how daunting and many hours later, the following is a collection of some favorite images from this past year, beginning with the male Snowy Owl photographed at Captain Joe’s dock last winter, to December’s Red-tailed Hawk huntress.
Living along the great Atlantic Flyway, we have been graced with a bevy of birds. Perhaps the most exciting arrival of all occurred when early summer brought several pairs of nesting Piping Plovers to Gloucester’s most beloved (and most highly trafficked) of beaches, Good Harbor Beach. Their story is being documented on film.
While photographing and filming Red-winged Blackbirds this past spring, there was a face-to-face encounter with a hungry coyote, as well as several River Otter sightings.
The summer’s drought brought Muskrats out from the reeds and into full view at a very dry Henry’s Pond, and a short film about a North American Beaver encounter at Langsford Pond. Numerous stories were heard from folks who have lived on Cape Ann far longer than I about the extraordinary number of egrets, both Snowy and Great, dwelling on our shores.
There were few Monarch sightings, but the ones seen thankfully deposited eggs in our garden. Thank you to my new friend Christine who shared her Cecropia Silkmoth eggs with me and thank you to the countless readers who have extended an invitation to come by and photograph an exciting creature in their yard.
Pristine beaches, bodies of fresh water, and great swathes of protected marsh and woodland make for ideal wildlife habitat, and Cape Ann has it all. With global climate change pushing species further away from the Equator, I imagine we’ll be seeing even more creatures along our shores. Butterfly and bee populations are overall in decline, not only because of climate change and the use of pesticides, but also because of loss of habitat. As Massachusetts has become less agrarian and more greatly forested, fields of wildflowers are becoming increasingly rare. And too fields often make the best house lots. Farmers and property owners developing an awareness of the insects’ life cycle and planting and maintaining fields and gardens accordingly will truly help the butterflies and bees.
Thank you to all our readers for your kind comments of appreciation throughout the year for the beautiful wild creatures with which we share this gorgeous peninsula called Cape Ann.

I wonder what 2017 will bring?
