Viele märkische Wiesenvögel vom Aussterben bedroht

Die Naturwacht Brandenburg warnt vor einem Schwund bei den heimischen Vögeln. Dieser Rückgang erfasst nach Recherchen der Initiative immer mehr Arten. Die so genannten "Ranger" der Naturwacht, 92 derzeit, sind im ganzen Land an Flüssen und Seen sowie in Wäldern unterwegs. Dort bauen sie unter anderem Nisthilfen, messen Wasserpegel, errichten Fledermausquartiere oder pflegen Streuobstwiesen.

Survey says … ducks numbers way down in Texas

Over the past 20 years or so, Texas waterfowlers have witnessed - and waterfowl managers have documented and wrestled with - some dramatic shifts and trends in abundance and distribution of the ducks and geese that each autumn pour down the Central Flyway to winter in the state. That perspective is strikingly underscored by results of Texas' 2018 Mid-winter Waterfowl Survey. That aerial population survey, conducted in early January each year and covering all of the state except for the waterfowl-poor Edwards Plateau and Trans-Pecos ecological regions, produced some sobering findings.

Asian Waterbird Census shows 40 per cent decline in bird count

The Asian Waterbird Census (AWC) 2018 conducted in Kollam district by the WWF-India, a conservation organisation, with the support of Social Forestry wing of Kerala forests and wildlife department has found a drastic fall of around 40 per cent in the total count of birds. The AWC held in nine different bird rich sites accorded a count of 5,697 birds belonging to 61 species in place of the previous year’s count of 9,378 from 65 species. The number of migratory bird species has also fallen to 22 from last year’s 32.

Finnish populations of the pochard have fallen a staggering 80% in the past 20 years

Nature preservation group BirdLife Finland reports that domestic populations of the endangered common pochard have decreased massively in the past two decades. BirdLife's calculations show that Finnish populations of the common pochard (Aythya ferina) have fallen a staggering 80 percent in the past 20 years. The organisation hopes to help revive the species by naming it the year's top bird.In the early 1970s the Kokemäki river delta in Satakunta was bustling with some 250 pairs of pochards. Local calculations from a few years ago put the figure at just 30.

The Northern Pintail is in Steep Decline

The Northern Pintail (Anas acuta) is a dabbling duck. Diet is mostly plant material, including seeds of grasses, sedges, pondweeds, and waste grain in fields. In summer its diet includes more animal matter, such as insects, crustaceans, mollusks, and sometimes tadpoles and small fish. It forages in shallow water by upending or by submerging its head and neck while swimming, looking for food in the underwater mud. It also forages by walking on land.The North American Breeding Bird Survey noted a cumulative decline of the Northern Pintail population of 72% between 1966 and 2012.

Migratory birds in Chilika decline by over 50,000

Chilika lake is a brackish water lagoon, spread over the Puri, Khurda and Ganjam districts of Odisha state on the east coast of India, at the mouth of the Daya River, flowing into the Bay of Bengal, covering an area of over 1,100 km2. It is the largest coastal lagoon in India. The number of migratory birds has declined by 53,729 in Odisha’s Chilika and Nalabana Bird Sanctuary this winter as compared to previous year, the annual bird census revealed.

Hong Kong’s most endangered species

The black-faced spoonbill (Platalea minor) has the most restricted distribution of all spoonbills, and it is the only one regarded as endangered. There remain only about 3,300 spoonbills, and the species spends the mating season on small islands along the west coast of the Korean Peninsula and in China’s Liaoning province, the WWF says. “With such a small global population, the black-faced spoonbill is inherently vulnerable to extinction,” it says.

The curlews are one of the most threatened bird species on the planet

The Numeniini — a tribe of large waders including curlews and godwits — is one of the most threatened bird groups on the planet. The once-abundant Eskimo Curlew Numenius borealis of the Americas is now considered Critically Endangered (Possibly Extinct), having last been spotted with certainty in the 1960s. Like the Eskimo Curlew, the possibility of the extinction of the Slender-billed Curlew (Numenius tenuirostris) cannot be confirmed for sure until we have scoured the entirety of its known breeding grounds in the Siberian wilderness for a remnant population.

Hooded grebes have become a critically endangered species

Argentina is the birthplace of tango, an iconic dance style dating back to the 1880s. Long before the first tango steps were taken, however, another dance was already in full swing across parts of Patagonia: the hypnotic grooves of the hooded grebe (Podiceps gallardoi). That dance is still going on today, as you can see in "Tango in the Wind," a new documentary about hooded grebes. Yet despite their impressive moves, the hooded grebes' dance is increasingly in danger of disappearing.
