2021 Nesting Season Updates

Update Early April 2021 – Annie and Squam (at least we thought at first it was him) returned to the nest earlier this year – probably around April 5-7. The webcam went live on April 13 and new nesting materials had been brought to the nest. However, we have observed a banded Opsrey at the nest on April 13 and 14, which would not be Annie or Squam. So we will have to watch and wait to see what unfolds here.
Update April 15, 2021 – Watching the Osprey pair on the webcam now for the past few days, we have noticed that the male Osprey has a US Fish and Wildlife Service aluminum band on his right leg. I have banded over 200 Osprey chicks in the past 5-6 years and all on the right leg. Squam was not banded and it is highly unlikely he would have been banded during migration. Plus, this banded male is a large Osprey who appears almost equal in size to the female, who looks very much like and we believe is Annie. Squam was noticably smaller than Annie. About noontime today, the banded male attempted to copulate with Annie. Since then there has been a third Osprey around the nest and much commotion, including a lot of chasing and calling.
It will take more time to determine what is going on here. Are two males competing to be Annie’s mate. Did something happen to Squam or did this larger male just outcompete him? These are all possible scenarios that will unfold in the coming days. Stay tuned!

2020 OSPREY PRGRAM YEAR IN REVIEW
Beautiful Ospreys are returning to Massachusetts nesting sites. Annie and Squam, Cape Ann’s resident pair, are actively re-establishing their bond, arranging the nest and courting. Their nest is located in the marsh behind Lobstaland and when driving past, you can often catch sight of the pair’s nesting activity. Annie and Squam’s nest is managed by Essex Greenbelt’s director of land stewardship, Dave Rimmer.
Osprey courtship is wonderfully fun to observe. Pairs typically mate for life and seem to simply enjoy hanging out together in the nest. They return each year to an established nest site, which is always near water and may be at the top of a dead tree, cliff, rocky outcropping, or manmade structure including Osprey nesting platforms, telephone poles, channel markings, and even church rooftops (see last photos)! By reusing the same nest from year to year a ready-made nest allows for earlier egg laying, which generally leads to greater success. And if the first nest fails, there may be time to try again.
I didn’t see the male delivering fish to the female or the Osprey’s famous courtship flight; hopefully another day 🙂
How to tell the difference between male and female Osprey. The female of a pair is oftentimes, but not always, larger than the male, by as much as twenty percent in some instances. But unless you see them side-by-side from exactly the same angle, that can be difficult to compare. Females may also have a more prominent ” necklace,” sometimes referred to as “freckling,” around the neck. Her feather necklace patterning is usually more pronounced. You can see the difference in the photo below.
Osprey are one of the largest birds of prey, with a wingspan of five feet.
Osprey are found worldwide, in every continent except Antarctica.
The oldest Osprey lived to be 30 years old.
Osprey are recovering from the use of the pesticide DDT, which caused breeding failure from eggshell thinning. DDT was banned in 1972.
Ospreys are piscivorous, with fish comprising 99 percent of their diet.
When an Osprey catches a fish, it arranges the fish head first, reducing aerodynamic drag.
Poor little Sharpie didn’t stand a chance of going unnoticed. The Eastern Point Crow Patrol was all over him, cawing vociferously and dive-bombing, alerting every creature within earshot of his presence. The juvenile Sharp-shinned Hawk held his ground for a bit, before tiring of the sky guardians and heading for cover into a nearby tree.
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.
This juvenile Red-tailed hawk was perched in a tree on the roadside running along the Great Salt Marsh. She was hunting a squirrel that was half hidden in the leaf litter below. This is the second time in the past several weeks that we’ve seen a Red-tailed Hawk hunting and eating a squirrel. The first was in our neighbor’s yard, perched on the stone wall, eating a Gray Squirrel. The Red-tailed flew overhead with the squirrel in its beak and landed on the lattice of our outdoor shower enclosure. My husband stood beneath the shower ceiling and watched for a bit as the hawk finished off his meal.
The Red-tailed Hawk’s diet is highly variable, consisting of small mammals including voles, mice, rats, rabbits, and squirrels; other birds including bobwhite, starlings, blackbirds, ducks, and pheasant; reptiles such as snakes and frogs; fish; insects; bats; and carrion. They are colloquially called “chickenhawks” however, they rarely take a standard-sized chicken.
The Red-tailed Hawk is the most common bird of prey found in North America. We saw several in Mexico on our trip to Cerro Pelon in early March. They are found from the interior of Alaska and northern Canada to as far south as the West Indies and Panama.
Local lore has it that the house was built in 1922 by a couple who were in the process of divorcing and sorting their affairs. The wife asked that the husband build a replica of their Newburyport family home. She did not say where the house was to be sited. Out of spite, he built the house atop the isolated salt marsh, with only saltwater plumbing.
The Pink House has not been occupied since the early 2000s and looks worse with each passing year. Last winter I was at the refuge for a program held at the PRNWR headquarters. After the event I tried to drive towards Plum Island but with sea water gushing in from the marsh, the road in front of the house was dangerously impassable.
The house is FREE, if only you will either take it off the marsh or give Parker River National Wildlife Refuge a few acres of comparable land. The second option allows for the house to stay in its current location. Read more here: Free Pink House of Newbury: Take Me I’m Yours
