2017 Osprey Nesting Season

March 25, 2017 the first osprey returned to the nest (coincidentally this was the same date as last year)

Marcy 27, 2017 the mate returned.

Osprey mate for life, but after breeding the osprey go their separate ways as they migrate, only to return to the family nest, so it seems unbelievable that they can come back from South America after being apart for months, within days of each other!

What type of fish are those Osprey eating?

As we have been watching the osprey bringing in fish we've been trying to identify the species they bring in. So far we have clearly identified peanut bunker and perch. One of our osprey watchers has also seen koi (which are an ornamental  sub species of carp bred and sold for their beauty, a favorite in ponds)  Carp is a very hardy fish, tolerating more extreme temperatures than other fish. They are like the goats of the fish world, eating everything in its path, snails, plants, fish eggs and vegetation.

If you spot a different species of fish email us and we will add it to the list, or get a screenshot of it and we will try to identify.

Will eggs be coming soon?

The Ospreys have been doing more work on their nest and it's starting to come together in a bowl shape. Will we be seeing eggs in the next few days?

A nest bowl is starting to take shape.

Prove you're a good provider!

One of the ways that an Osprey pair strengthens its bond is the male going fishing for the female. When the female wants a fish she will start calling -  cheep, cheep, cheep - ever more frantically if the male doesn't fast leave enough. Eventually the male will go off, catch a fish, and return, and as he comes into his mate's view she will again start calling - cheep, cheep, cheep. After he lands on the nest, she will continue to call until he gives up the fish and she eats.

The female Osprey seems pleased with the fish that her mate brought back to the nest.
By bringing his mate fish the male is also demonstrating that he will be a good provider for the chicks when they hatch and need ever increasing amounts of fish as they grow. If the nest is successful three chicks can eat up to 60 pounds a day before they fledge.

More about telling male and female Ospreys apart

Female Osprey (L) has a streaked breast. Male (R) has an almost clear breast.
The difference between the female Osprey's breast marking and the male's relative lack of breast marking is clear in this image from the Osprey cam.

If you are watching the nest cam and cannot see the breast of the Ospreys, these two have another distinguishing feature. The male has a distinctive partial eye ring that breaks up the dark eye stripe behind the eye. The female's eye ring is narrower and in some views almost invisible.

The male's partial eye ring is more pronounced than the female's.

Nest building

The first task for Ospreys returning to their nest site is to repair and improve the nest. In addition to making a better nest the activity reestablishes the bond between the pair.

Before our volunteers installed the camera the old nest and platform were replaced with a new platform better able to support the camera. As with all of the other Osprey platforms we've replaced a small amount of grass and sticks were added as starter material.

A Belted Kingfisher visited the nest platform before the Ospreys returned.
The starter nest material didn't cover the wire mesh.
After the Ospreys returned on Saturday, March 26, they started building a proper nest. By Monday, March 28, they had made great progress.

The Ospreys made a lot of progress in two days.
