This rare thrush attracted many birders to the dike above the backyards of Vlieland village.
This is also an 21 October 2017 eyebrowed thrush video, but not especially on the Vlieland individual.
This 29 September 2017 cell phone photo is from the ship from Harlingen harbour to Vlieland island in the Netherlands.
Do people really eat shit on Vlieland?
No: the content of the boxes is licorice.
Study debunks fishy tale of how rabbits were first tamed. A pope’s proclamation that bunnies are fish, so can be eaten for Lent may never have happened. By Tina Hesman Saey, 1:30pm, February 14, 2018.
This video shows an oystercatcher in Norway.
From the University of Amsterdam in the Netherlands:
Oystercatcher (Haematopus ostralegus) populations in the Netherlands have dramatically declined during the last decades. CHIRP (Cumulative Human Impact on biRd Population) aims to determine which pressures in breeding and wintering areas cause the observed negative population trend. In winter, the Wadden Sea harbours large numbers of oystercatchers. Despite the vast amounts of shellfish available on the mudflats, oystercatchers encounter multiple difficulties in their wintering areas. For example, food stocks become more limited by fishery and the increase of the Pacific oyster. Furthermore, the Wadden Sea area is used for many different recreational purposes, causing disturbance of waders from the land, water and air. Walkers, cyclists, boats and airplanes are a few examples of disturbance sources present in the Wadden Sea. Disturbance might have direct energy costs for oystercatchers if the birds need to take flight or indirect costs if the foraging efficiency decreases due to a more alert state of the bird. Ultimately, this might affect body condition and survival of wintering oystercatchers.
The Vliehors is a large sandflat located at the western half of the Wadden Island Vlieland. The sandbanks serve as high tide roosts for large numbers of waders that forage on the tidal mudflats south of Vlieland. However, the area is owned by the military airforce and in use as training ground for helicopters and jet fighters which practice by shooting and throwing bombs at specific targets. During this research, we aim to study how disturbances like military air force planes affect the behaviour and time budgets of oystercatcher.
For this project, wintering oystercatchers at the Vliehors are equipped with UvA-BiTS GPS trackers during the seasons 2016-17, 2017-18 and 2018-19.
The GPS and accelerometer data will be linked to disturbances that take place on the Vliehors. Besides the activities of the military airforce, those disturbances include walkers and cyclists on land in the weekends and hand-raked cockle fishers on the mudflats with settled weather conditions. The frequency and effects of these disturbances will be recorded during the winter seasons. Linking field observations to GPS and accelerometer data will then yield valuable information on how different disturbances affect spatial distribution and time budgets of oystercatchers.
Translated from the blog of wildlife warden Anke Bruin-Kommerij on Vlieland island in the Netherlands today:
Yesterday, at the end of a hot working day, our colleague Pieter Schaper was called by Gerda Stel. She saw a young spoonbill in distress near Pad van 20 footpath on the mudflats. The bird had its leg stuck in a breakwater and it was rising tide …. So, speed was needed and then you just have to have Pieter! He did not think twice and went in his working shoes on the mudflat in order to save the young spoonbill. This rescue succeeded, but the work shoes were still not dry today.
This video says about itself:
Peregrine Falcon (Falco peregrinus) at beach, timid about taking a bath
Peregrine Falcon (Falco peregrinus) at the beach tentatively approaches the water and comes back out before finally deciding to bathe.
Peter de Boer (of Dutch Sovon bird research) and Dutch Vlieland warden Carl Zuhorn write today of the first time ever, as far as is known, that a peregrine falcon couple has nested on the island. This species is still rather rare in the Netherlands: about 150 couples.
The nest is on the Vliehors sandy plain, in the west of Vlieland.
The couple started breeding about 10 May 2016 on the sandy ground. One young falcon, a female, hatched. Her mother had been ringed: she was born on 21 May 2010 on Trischen island in the German Wadden Sea.
On 1 July 2016, the young peregrine was ringed. She fledged on 18 July.
