HAWK-ON-THE-HUNT JOINS US AT CAPT. JOE’S FOR THE GMG PODCAST

Perched on the lobster traps, I only had a fleeting moment to take a photo pulling into the parking lot at Captain Joe’s. While getting my camera out, the Hawk appeared to pop into a lobster trap. He popped back out, I took a snapshot under cover of car, then off he flew.

Raptors such as Sharp-shinned Hawks and Peregrine Falcons are attracted to lobster pots because the traps often house songbirds such as sparrows. The smaller birds eat the crusty tidbits found on the pots and the larger birds have learned to find a tasty meal there.

Several years back when there was a male Snowy Owl at Captain Joe’s, a Peregrine Falcon flew on the scene, defending his territory by repeatedly dive bombing the Owl. The Falcon disturbed him so much so that the Snowy eventually departed.

Snowy Owl Besties on the Beach

When one Snowy Owl boy left his perch and flew within several feet of a second Snowy stationed further down the beach I wasn’t sure what to expect, especially after witnessing several territorial battles between Hedwig and Bubo last winter, as well as a Snowy dispute between a male and female at Crane Beach.

These two behaved as if they were expecting a visit from their best bud. After landing next to the stationary one, the active one immediately began to eat seaweed. This went on for several minutes.

Then he washed his big feet and fluffed his feathers. Both nodded and dozed off, like it was the most normal thing to hang with a Snowy bestie on the beach. They were spotted a few days later again, not too far apart 🙂

Happy Palentine’s Day

Two Snowy Boys

NOT ONE, BUT TWO SNOWY OWL BOYS!

Not one, but two, Snowy boys were well camouflaged amidst the rocks. They were far apart from one another when one flew toward the other. The stationary fellow didn’t move an inch and barely opened his eyes, while the flying fellow hid himself expertly behind a clump of dry wildflowers. The two sleepily hung out together, positioned not twenty feet apart.

I wished I could have stayed to see if they would behave territorially, but frozen fingers chided me off the beach.

I see you little Snowy Boy!

A flock of Snow Buntings foraged in between the rocks and they too were well-camouflaged.

Superb Owl Sunday

Here’s my Superb Owl Sunday photo, which I forgot to post on Sunday. Since the photo was actually taken on Super Bowl Sunday, I thought better late than never.

Snowy Owl Sleeping – Please Do Not Disturb

I dream about Snowies sometimes, especially in wintertime. I wonder if Snowies dream–probably, if they do, its all about tasty morsels 🙂

Do Snowy Owls, like other owl species, feed at night?

Snowy Owls are crepuscular (active and feed at dawn and dusk), diurnal (hunt during the day time), and nocturnal (hunt during darkness). Mostly, while wintering in our region, they rest during the daylight hours. When you see a Snowy sleeping, whether on the beach, a fence post, rooftop, or tree, please give him/her lots of space and let him rest quietly and undisturbed.

In the summer months, Snowies feed in the continuous daylight hours of the Arctic. Their main source of food is lemmings. In years when lemmings are super abundant, female Snowies will actually lay more eggs! Both the male and female hunt and bring food to the growing owlets. Feeding a hungry brood of baby owls is nonstop during the long days of the Arctic summer, and the owls also cache food.

What do Snowy Owls eat when wintering over in New England? I’ll share what we saw Hedwig eat because I am reading tons of misinformation posted online. We saw her eating rabbits, shrews, rats, mice, and yes, sea ducks. At day’s end, she would leave her hotel perch, sometimes heading over the golf course for a rabbit, or swooping down to the rocky shoreline for a shrew, or out to sea for a Common Eider or Bufflehead.

A Snowy Owl irruption occurs when there is an abundance of lemmings, which leads to an abundance of Snowy Owl hatchlings (more lemmings equals fewer hungry owlets), which leads to more fledglings. Easier-to-catch food is available for the less experienced young hunters further south in the lower 48 states. The adults typically keep north, the first- and second-hatch-year owls often head south. This is another reason to keep a respectful distance, many of the owls are still developing and growing.

Our Hedwig appeared especially adept at catching rodents that were scurrying between the rocks at Bass Rocks. In summer, Arctic Lemmings shelter in shallow underground burrows, or under rocks, just as do Cape Ann members of the rodent family.

Interestingly, some Snowy Owls move further north for the winter. They spend these darkest and most frigid of months at sea, ice hunting for Arctic birds at open patches of water.

FANTASTIC PRESENTATION BY CRANE BEACH ECOLOGIST JEFF DENONCOUR AT THE CAPE ANN MUSEUM

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.”
