Rare stone curlew in the Netherlands


This video from Greece is called Eurasian Stone-curlew (Burhinus oedicnemus).

Today, 18 July 2015, a rare stone curlew has been seen in ‘s-Gravenzande in the Netherlands.

Seabirds near Dutch coast, 2011


Red-throated loon with chick

In the Netherlands, there is now [November 2011] an artificial sandy peninsula in the North Sea, the “Zandmotor“.

From there, quite some seabirds have been spotted. Including gannets, guillemots, razorbills, and red-throated loons.

Abstract

This article presents results of an analysis of honey bee losses over the winter of 2011-2012 in the Netherlands, from a sample of 86 colonies, located at 43 apiaries. The apiaries were selected using spatially stratified random sampling. Colony winter loss data were collected and related to various measures of colony strength recorded in summer, as well as data from laboratory analysis of sample material taken from two selected colonies in each of the 43 apiaries. The logistic regression model which best explained the risk of winter loss included, in order of statistical importance, the variables:

(1) Varroa destructor mite infestation rate in October 2011, (2) presence of the cyano-substituted neonicotinoids acetamiprid or thiacloprid in the first 2 weeks of August 2011 in at least one of the honey bee matrices honey, bees or bee bread (pollen), (3) presence of Brassica napus (oilseed rape) or Sinapis arvensis (wild mustard) pollen in bee bread in early August 2011, and (4) a measure of the unexplained winter losses for the postal code area where the colonies were located, obtained from a different dataset.

We consider in the discussion that reduced opportunities for foraging in July and August because of bad weather may have added substantially to the adverse effects of acetamiprid and thiacloprid. A novel feature of this work is its use of postal code random effects from two other independent datasets collected in the annual national monitoring by questionnaires of winter losses of honey bees in the Netherlands. These were used to plan the sample selection and also in the model fitting of the data in this study. It should however be noted that the results of the present pilot study are based on limited data, which may consequently reveal strong factors but fail to demonstrate possible interaction effects.

As one of the authors of this explained this morning on Dutch radio, acetamiprid and thiacloprid are considered to be ‘harmless’ compared to other neonicotinoids. However, even they …
