Meet the Natives: Wild Bees

27 August 2013

Follow University of Wisconsin-Madison Entomologist Claudio Gratton as he studies native bees and their habitats in search of new options for pollinating plants.

Warden Arden Bruin reports about discoveries by entomologist Arie Koster about bees on Vlieland island.

After 1980, over forty wild bee species have been seen on Vlieland. Probably there are more, as there has not been that much research.

This year, two species, new for the island, were seen in 2014: European wool carder bee and Hylaeus hyalinatus.

Unfortunately, the moss carder bee was not seen this year, though it had been seen in earlier years.

First ever glossy ibis nest on Vlieland island?


This video is called Glossy Ibis at Chapel Amble – Wildlife in Cornwall.

Warden Anke Bruin reports from Vlieland island in the Netherlands about a glossy ibis couple in Kroon’s polders nature reserve.

The normal glossy ibis nesting time, in the Mediterranean, is May-July.

Could this be the first time ever of a glossy ibis nest in the Netherlands? Ms Bruin asks.

In 2012, a glossy ibis couple started to make a nest in the Netherlands, but did not continue.

Rare bee orchid discovery on Vlieland island


This video is called The bee orchid, Ophrys apifera | Natural History Museum.

Bee orchids are rare flowers in the Netherlands.

They are known from Texel and Terschelling islands.

Recently, fifty flowers were discovered on Vlieland island.

Join us in preserving the nests of the spoonbills of the island of Nair in Mauritania

11 December 2013

The subspecies balsaci of Eurasian Spoonbill (Platalea leucorodia) is present only in the PNBA. One of the most important nesting sites is on the island of Nair which is two hours windsurfing sailing from the village of Iwik. Birds by preference build their nests on the vegetation which lines the fragile dune that acts as a natural barrier on the coast. Unfortunately in recent years, the sea has been gaining ground on the island and is progressively flooding nests.

To preserve this rare bird, Ahmed and his Imraguen friends, with the help of FIBA, Natuurmonumenten and the local ONG «Nature Mauritania» filled gaps in the dune by placing sandbags. These sandbag barriers reduce recurrent flooding and enable the vegetation regeneration necessary for successful spoonbill breeding.

Petra de Goeij, Dutch spoonbill biologist, reports on female spoonbill YfLY/aLY.

Born on Vlieland island, she had nested on Schiermonnikoog island in 2013.

This bird had a data logger on, enabling scientists to find out where she had been.

Translated, about 2014:

First, she went to Schiermonnikoog from April 6 until April 25. From there she flew that day to the Lauwersmeer, and after a shorts break on Ameland island, to Vlieland. There, she went first to the Kroonspolders but on 30 April she decided to go to the Oude Huizenvallei. And there she is nesting now.

During the winter of 2013/2014 she had wintered in the Morbihan in Brittany. If you look at her life basing oneself on her colour rings, she appears to have done that every winter since 2006. And, coincidentally, she was born on Vlieland in the Oude Huizenvallei.

Spoonbill and plover news from Vlieland island


This video is about two Kentish plovers in Cornwall.

Warden Carl Zuhorn reports about birds on Vlieland island in the Netherlands.

This spring, so far there are about 160 spoonbill nests at five places on Vlieland. Some spoonbills are still returning now from spring migration.

On the Vliehors, the west of the island, there are three Kentish plover nests.

Otte Zijlstra made this video.

There were two snowy owls in the sand dunes of Vlieland.

Unfortunately, one of them has died. A tourist found it at Dodemansbol (Dead man’s dune). The cause of its death is under investigation.

Shark beaches alive on Vlieland island

Dylan Irion, Swimming Behaviour of the Common Smoothhound Based on Accelerometer Data

A thorough understanding of the behaviour and habitat use of sharks is critical for improving our understanding of the movement ecology and thus the effective conservation of these threatened species. Direct observation of sharks is often difficult to accomplish in the marine environment where access to free-swimming individuals can be restricted by numerous factors.

The miniaturisation and reduced costs of producing sensors for bio-logging has provided several solutions to overcome this obstacle. The accelerometer is a sensor that functions by recording changes in acceleration due to the dynamic motion of a body, and the static acceleration caused by gravity.

In this study I demonstrate the potential for utilising tri-axial accelerometry as a method for characterising the movement of sharks. By attaching accelerometers to captive common smoothhound sharks (Mustelus mustelus) and comparing the accelerometer record to visual observations of their behaviour, I was able to detect tail beat frequency, tail beat amplitude, and body posture.

Shark strands alive on Vlieland

Update: Monday 24 Feb 2014, 13:48

On Vlieland, a living shark, more than a meter in size, has beached. Never before such a large shark had washed up [alive] on the Dutch coast. It is a starry smooth-hound shark normally only found in warmer seas.

Hikers found the exhausted shark yesterday on the beach. The fish is injured on its muzzle. It was put back into the sea, but kept beaching again and again. That’s why people brought it to the aquarium in the nature center De Noordwester on Vlieland.

The starry smooth-hound shark is not dangerous to humans. It has no teeth and only eats crustaceans such as shrimps.

According to Dutch daily Algemeen Dagblad, the shark shows signs of recovery.
