The Numeniini bird family faces extinction

For Numeniini, a family of birds that includes Curlews and Godwits, new research indicates that these birds are at risk. A recent study by Royal Society for the Preservation of Birds (BirdLife in the UK), British Trust for Ornithology (BTO), and the International Wader Study Group suggests they could actually be one of the most threatened families of birds on earth. The study consulted over 100 experts who assessed the threats to Numeniini throughout their migratory regions and found that seven of the thirteen species are threatened with extinction.

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.
