Veel broedvogels van de toendra gaan achteruit

Van de 263 onderzochte vogelsoorten die Nederland aandoen als doortrekker of wintergast zijn er 39 op de nieuwe ‘Rode Lijst’ van bedreigde vogels terecht gekomen en negen op de oranje lijst. De oranje lijst is een lijst van vogels die de afgelopen tien jaar constant in aantal zijn afgenomen en dus ook in de gevarenzone dreigen te komen. Van de wintergasten en doortrekkers die in ons land achteruit zijn gegaan, broeden er zo’n dertien op de toendra.

Störche sind im Landkreis Nordwestmecklenburg stark gefährdet

Immer weniger Weißstörche (Ciconia ciconia) brüten im Landkreis Nordwestmecklenburg. Gerade einmal 27 Paare wurden im vergangenen Jahr von den aktiven Weißstorchschützern des Naturschutzbundes (Nabu) gezählt. 1996 waren es noch 95 Paare. Die Schuld an dem Rückgang geben die Naturschützer der veränderten Kulturlandschaft in Mecklenburg-Vorpommern. Hecken und blütenreiche Ackerrandstreifen suche man mittlerweile vergebens. Feuchtwiesen werden entwässert und als artenarme, intensiv genutzte Grünländer genutzt.

Population of large gulls in Scotland failed to thrive as local fish catch fell

The research, published in the British Trust for Ornithology (BTO) journal Bird Study, looked at the breeding populations of three species of large gull; Herring Gull (Larus argentatus), Great Black-backed Gull (Larus marinus) and Lesser Black-backed Gull (Larus fuscus) on the Hebridean island of Canna, and the relationship between these gull populations and the fall in the quantity of fish landed in the nearby harbour of Mallaig. Between 1985 and 2000 an annual average of 13,726 tonnes of fish was landed in Mallaig. However, between 2007 and 2014 this had fallen to 4,456 tonnes.

Shorebird populations have shrunk by 70% across North America since 1973

Shorebird populations have shrunk, on average, by an estimated 70% across North America since 1973, and the species that breed in the Arctic are among the hardest hit. The crashing numbers, seen in many shorebird populations around the world, have prompted wildlife agencies and scientists to warn that, without action, some species might go extinct. Although the trend is clear, the underlying causes are not. That’s because shorebirds travel thousands of kilometres a year, and encounter so many threats along the way that it is hard to decipher which are the most damaging.

The black rail is disappearing from Virginia

As a species, the eastern black rail (Laterallus jamaicensis) tops the list for avid bird-lovers the world over who are eager to catch a glimpse of this reclusive, secretive little creature. That’s because most birders have never actually seen one in the flesh. And most of them never will. In just a few short years the night calls of the eastern black rail have gone silent in many coastal states. In Virginia, for instance, there have been no recorded sightings in two years.

Dramatic decline of Puerto Rico’s shorebirds

North American shorebirds have declined significantly over the past several decades. As a result, ornithologists have carried out numerous studies to identify key habitat for preservation and develop conservation strategies. Most of this research has been conducted on northern breeding grounds or on wintering grounds in South America, but there have been few studies in the Caribbean.

New Zealand Has the Most Seabirds on the Planet, and 90 Percent Are at Risk

A new report from the New Zealand government found that 90 percent of the country’s 92 seabird species—the highest concentration of seabirds on the planet—are threatened with extinction. Among the most threatened species are the Antipodean albatross (Diomedea antipodensis), the eastern rockhopper penguin (Eudyptes chrysocome filholi), the Pitt Island shag (Phalacrocorax featherstoni), and the New Zealand fairy tern (Sternula nereis davisae). Despite being legally protected in New Zealand, many of these species have falling populations.

Declining bird populations on Sydney’s lower north shore

Ornithologist Dr Andrew Huggett, of Insight Ecology, studied 25 sites across the Willoughby LGA in December 2015 and August 2016. He said the two surveys, at breeding and non-breeding periods, were undertaken in the area’s remnants of native bushland, including H.D. Robb Reserve, Explosives Reserve, Gore Hill Cemetery and three local golf clubs. “The aim was to determine what bird species occurred in their bushland, reserve and parks, but also along the Gore Hill Freeway,” he said.

The spoon-billed sandpiper population declined from 2,000-2,800 pairs in the 1970s to less than 250 pairs in 2014

The spoon-billed sandpiper Calidris pygmaea is one of the most threatened birds on the planet. It breeds on the Chukotsk and Kamchatka peninsulas in the Russian Far East, migrates through Russia, Japan, North Korea, South Korea and the Jiangsu coast of China to winter in southern China, Bangladesh, Myanmar and Thailand, 8,000km from its breeding grounds. Its IUCN threat status was upgraded from Vulnerable to Endangered in 2004 and to Critically Endangered in 2008.

Dozens of sick and dying magpies at Australia's Northern beaches as mystery illness strikes

THEY are best known for swooping and terrorising pedestrians but now it is the predatory magpies (Cracticus tibicen) who are fighting for their lives. A mystery illness has struck down record numbers of the black-and-white birds this year and puzzled wildlife officers are desperately trying to work out what is grounding the winged warriors. Wildlife Information, Rescue and Education Service (WIRES) volunteers have reported seeing dozens of sick and dying magpies on the northern beaches in recent days.
