2021 Nesting Season Updates
Please send any questions to firstname.lastname@example.org)
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.
On my morning PiPl check, I met up with a super nice gentleman, Bill, who walks the beach every morning. He loves wildlife (including PiPls), is a Coast Guard veteran, was a fisherman, and grew up on a marsh. Bill pointed out the whale (or he thought possibly a large dolphin), breaching and blowing blow holes off in the distance. Bill mentioned there had been a crowd along the back shore earlier and that there is tons of good bait fish off the coast right now.
How exciting at see an Osprey swoop in and snatch up a large fish precisely where the whales were fishing. All were too far away to get some really fine shots, but you can at least get an idea from the photos.
PiPl Update- all three fledglings are doing beautifully on this, their 39th day 🙂 The three spent the hours of five to seven mostly foraging in the area front of the enclosure, and also preening within the enclosure. Papa was on the scene, too.
