Northern wheatears back nesting on Schiermonnikoog island


This video from England says about itself:

Close inspection of nale & female northern wheatears (Oenanthe oenanthe) at Thorpe Marsh Nature Reserve, spring 2012.

Northern wheatears are declining as nesting birds in the Netherlands.

Fortunately, in Dutch Trouw daily, 12 July 2019, Koos Dijksterhuis reported that he had seen a young northern wheatear on Schiermonnikoog: proof that they had nested on the island.

They had been away for years. Conservation organisation Natuurmonumenten recently had made a sand dune valley more fit for northern wheatears. And it had worked.

Shark egg with living embryo found


This video says about itself:

Small-spotted catshark embryo is moving inside the egg

… Video displays how it is swimming and waving his tail inside the egg.

Video is created by me, soundtrack is a classic song “Song of the Indian Guest” created by composer Nikolai Rimsky-Korsakov who died in 1908 (more than 100 years ago).

Translated from Dutch NOS TV today:

Fishermen just off the coast of Schiermonnikoog have found a shark‘s egg containing a living embryo. The RTV Noord website shows a video with the wriggling baby shark.

It is an egg of a small-spotted catshark, a small shark of about one meter long. The small-spotted catshark is common in the North Sea and the discovery of a shark’s egg is not so special, but a living embryo is.

“We sometimes find empty egg capsules on the beach, but I’ve never seen a live shark in an egg,” says Marijke Barhorst of the Visitors Centre of Schiermonnikoog National Park.

The visitor center staff have put the shark‘s egg inside a culture dish in a saltwater aquarium, hoping that it will hatch.

Bearded vulture over Dutch Ameland, Schiermonnikoog islands


This video shows adult and young bearded vultures; and some griffon vultures and ravens, in Spain.

Dutch NOS TV reports that this afternoon, a young bearded vulture flew over Ameland and Schiermonnikoog islands. For some time, a buzzard flew along with the vulture, showing the big size difference.

This vulture has a transmitter, showing it is originally from central France. Bearded vultures are very rare in the Netherlands.

I have been to Ameland and Schiermonnikoog, but I never saw any bearded vulture there. Though I did see them in Aragon in Spain.

What brent geese eat, new research


This ideo is called Brent geese (Branta bernicla) grazing on grassland.

Translated from BirdLife in the Netherlands:

Jan 26, 2016 – Brent geese preferably eat non salty salt marsh plants. Salty plants are avoided. The protein content of the plant apparently leaves the birds cold. That concludes PhD researcher Wimke Fokkema based on measurements of plants in the marshes of Schiermonnikoog island. The research is published this month in the journal Oikos.
