Weidevogels

Negen soorten broedvogels zijn in Nederland uitgestorven en 87 soorten worden nu in hun voortbestaan bedreigd

Het aantal bedreigde broedvogels in Nederland neemt toe. Er staan negen broedvogels meer op de Rode Lijst dan in de vorige publicatie in 2004. Onder meer de torenvalk (Falco tinnunculus) en de wulp (Numenius arquata) staan er nu ook op. Op basis van tellingen van Sovon Volgelonderzoek is te zien welke soorten er zijn verdwenen en welke broedvogels het snelst uitsterven.

The Yellow-Breasted Bunting is on the verge of extinction

The yellow-breasted bunting (Emberiza aureola), a once common migratory bird, has been driven to the brink of extinction in recent years. The species was reclassified as“critically endangered” on the red list of threatened species by the International Union for Conservation of Nature on Tuesday. The status is one step from the highest level of“extinct in the wild”. Back in 2000, the species was listed under“least concern”, the lowest level on the six-grade alert system.

Ely and Cambridgeshire farmland bird numbers decline by 9 per cent over 5 years

Bird numbers in Ely and Cambridgeshire have declined around British farmland by almost a tenth, according to new figures released by Defra. The latest figures released on Thursday (23rd November) by the government's environmental department reveal that wild bird numbers have dropped 9% from the years between 2010 and 2015, and by almost 70% by 1970. The figures have led the RSPB to call for a shift in how the UK operates its farming policies after it leaves the EU, to a more environmentally and sustainable friendly system.

De populatie grutto’s blijft krimpen

In 2017 zijn er circa 12.000 grutto’s (Limosa limosa) uitgevlogen. Helaas geen reden voor een feestje. De populatie grutto’s blijft krimpen. Om de huidige populatie (nu circa 34.000 paren) op peil te houden zouden er het afgelopen broedseizoen circa 18.000 jongen groot moeten zijn geworden. De grutto, onze Nationale Vogel, blijft in Nederland met gemiddeld 3,5 procent per jaar achteruit gaan.

Latest update of European wild bird indicators confirms continued decline of farmland birds

The latest data on European common birds, brought together by the Pan-European Common Bird Monitoring Scheme (PECBMS), shows a continued decline of European farmland birds. While the common forest birds are more or less stable over the last 10-15 years, the farmland birds show a staggering decline of 55% since 1980.

De Zuid-Hollandse boerenlandvogels staan door jarenlange bezoedeling van het landschap met imidacloprid op de rand van uitsterven

De dalende trend op het gebied van biodiversiteit in Zuid-Holland blijft aanhouden. Met name de natuur in het agrarisch gebied en de meest kwetsbare soorten van de zogenaamde rode lijst hollen hard achteruit. In navolging van vorige jaren blijkt uit een recent verschenen rapport van het Kennisinstituut Alterra dat de Zuid-Hollandse biodiversiteit een dalende trend blijft vertonen.

The prairie-chicken has lost as much as 84 percent of its historic prairie and grassland

The lesser prairie-chicken (Tympanuchus pallidicinctus) belongs to the grouse family of birds so iconic to prairie culture. This brown-barred, stocky species nests in shrubbery and grasses of the Texas panhandle, Oklahoma, New Mexico, Kansas and Colorado. David Hunter, owner of Hunter’s Livestock Supply in Woodward, recollected that the prairie-chickens were often spotted on his family’s 120-year-old farm in eastern Woodward when he was young. “There were just thousands of them everywhere,” the 57-year-old told me.

Wild pheasants disappearing in California

Things aren’t looking good for wild pheasants in California, where populations of the colorful game birds have fallen to less than 10 percent of what they were in the late 1990s. With pheasant (Phasianus colchicus) hunting season opening Saturday, state officials note populations of the bird have fallen dramatically over the past 19 years. Hunters reported shooting 4,828 pheasant roosters in 1998 on public lands in the Central Valley. But that number fell to 461 last year, according to the California Department of Fish and Wildlife.

"Regelrechtes Vogelsterben" in Deutschland

Die Zahlen, die der Naturschutzbund (Nabu) heute veröffentlichte, sind so alarmierend, dass Tierschützer bereits von einem "regelrechten Vogelsterben" sprechen. 12,7 Millionen Brutpaare gingen in nur zwölf Jahren verloren. Besorgniserregend ist vor allem der Rückgang bei verbreiteten Arten.12,7 Millionen oder 15 Prozent aller Vogelbrutpaare in Deutschland, das ist die dramatische Bilanz der heute veröffentlichten Auswertung. Diese beruht auf Vogelbestandsdaten, die die Bundesregierung 2013 an die EU gemeldet hat.

Insect-eating birds decline where bee-killing neonicotinoids are present

In his book, Dutch toxicologist Henk Tennekes (2010) makes the case that the contamination of surface water by neonicotinoids is so widespread in the Netherlands (and possibly elsewhere in Europe), that loss of insect biomass on a continental scale is behind many of the widespread declines that are being seen, be they of marsh birds, heath or meadow birds or even coastal species. This suggests that we should be looking at possible links between neonicotinoid insecticides and birds, not on a farm scale, but in the context of whole watersheds and regions.
