Irish bird populations suffering serious decline

Birdwatch Ireland's research has shown that the country has lost half a million waterbirds or almost 40% in less than 20 years. Among species in decline are Lapwing (Vanellus vanellus), Mallard (Anas platyrhynchos), Tufted Duck (Aythya fuligula), Goldeneye (Bucephala clangula) and Pochard (Aythya ferina). It says that there has been an "almost complete extermination" of farmland birds such as the Corncrake (Crex crex).

Feldvögel sterben aus

Schon 20 Feldvogelarten, darunter Braunkehlchen, Rebhuhn, Kiebitz oder Uferschnepf, sind rund um Kassel nicht mehr zu sehen, da diese Arten bereits ausgestorben sind. „Und um den Neuntöter ist es auch schon schlecht bestellt, ebenso um die Feldlerche, den Vogel des Jahres 2019“, sagen Manfred Henkel und Martin Lange vom Nabu Kaufungen-Lohfelden. Im Landkreis sei ihr Bestand dramatisch gesunken. Die beiden Naturschützer läuten Alarm. Nachdem vor rund einem Jahr das Insektensterben in den Medien ein großes Thema war, sind es nun die Feldvögel.

Canada’s grassland birds have plummeted in number since the 1970s

The North American Bird Conservation Initiative in Canada released the second State of Canada’s Birds report last week. The report, a joint project of Environment Canada and numerous government and conservation organizations, looks at the status of Canada’s bird populations going back to 1970.The study found that shorebirds, grassland birds, and aerial insectivores were in rapid decline across Canada, with numbers down 40, 57, and 59 per cent since 1970.

Für die Braunkehlchen ist es zwei vor Zwölf

Das Braunkehlchen (Saxicola rubetra) ist ein kleiner Singvogel, knapp so groß wie die allbekannte Kohlmeise. Es bewohnt Hochstaudenflure und feuchtes Grasland mit erhöhten Ansitzwarten. In Sachsen lebten Ende der 1990er Jahre noch etwa 4 000 Braunkehlchen-Brutpaare, aber schon sieben Jahre später hatte sich deren Bestand fast halbiert. Heute ist die Art großflächig verschwunden. Geringe Restvorkommen in Sachsen zeigen auch schon deutliche Inzuchtdepressionen, unteranderem verkrüppelte Füße.

Bird populations under stress

At least 314 species of American birds are expected to lose 50 per cent or more of their range by the end of the century, and have been listed by the Audubon Society as endangered. A United Nations science report says 1 million species of plants and animals are at risk of going extinct. Most at risk are sea birds and grasslands birds, experts say. Birds known as aerial insectivores, like swifts (Apus apus) and nighthawks (Chordeiles minor) , are at risk because the insects they depend on are getting harder to find.

Devon wildlife threatened by Extinction

At the recent Extinction Rebellion protest in Moretonhamstead as reported in the last edition of The Moorlander, one of the flyers the group were handing out brought attention to the worrying decline in Devon’s wildlife. A 90% decline in Greater Horseshoe bats (Rhinolophus ferrumequinum) has been seen, 97% of wildflower meadows have been lost since the 1930s, Nightingales (Luscinia megarhynchos) no longer breed in Devon; the last pair was recorded in 1993.

'Catastrophe' as France's bird population collapses due to pesticides

Bird populations across the French countryside have fallen by a third over the last decade and a half, researchers have said. Dozens of species have seen their numbers decline, in some cases by two-thirds, the scientists said in a pair of studies – one national in scope and the other covering a large agricultural region in central France. “The situation is catastrophic,” said Benoit Fontaine, a conservation biologist at France’s National Museum of Natural History and co-author of one of the studies.

Akker- en weidevogels lijken gedoemd te verdwijnen

Jaarlijks communiceert de Vlaamse Landmaatschappij over de inspanningen die landbouwers doen op vlak van agrarisch natuurbeheer. In functie van akkervogels voorzien ze bijvoorbeeld wintervoedsel en nestgelegenheid op hun percelen. Belangrijker nog dan de oppervlakte waarvoor beheerovereenkomsten afgesloten worden, is het resultaat dat daarmee geboekt wordt. Lokaal lijkt dat vruchten af te werpen, maar op Vlaams niveau blijven aan landbouw gebonden vogelsoorten als de veldleeuwerik en de grutto (Limosa limosa) verder afnemen.
