The yellow-crested cockatoo is on the brink of extinction

Habitat loss has pushed the critically endangered yellow-crested cockatoo (Cacatua Sulphurea), a native bird of Sulawesi and East Nusa Tenggara, toward the brink of extinction, as the number currently living in the wild continues to decline. The International Union for the Conservation of Nature (IUCN) has listed the bird among 20 bird species that are on the brink of extinction, said Tri Endang, head of the Forest Ecosystem Control unit at the West Nusa Tenggara Natural Resources Conservation Agency (BKSDA). “The IUCN has listed the Yellow-Crested cockatoo as critically endangered.

Where have the sparrows gone?

Where have all those chirpy little sparrows gone? Once a common sight, hopping away on the verandahs and chirping joyously from tree branches, the sight of a sparrow (Passer domesticus) has over the years become a rarity.The tentacles of development spreading with fast paced concretisation of the city have ended in choking away one of mankind’s oldest associate. As the city prepares to join the World Sparrow Day on March 20, it is left to a few individuals concerned at the fast decline in sparrow population, to bring them into focus.

Utrecht lokt vogels voor duurzame insectenbestrijding op sportvelden

De gemeente Utrecht start een proef, waarbij vogels en vleermuizen worden ingezet om schadelijke insecten op sportvelden te bestrijden. Het doel van de proef is om geen chemische bestrijdingsmiddelen meer te gebruiken. Voor de proef plaatste de gemeente dertig nestkasten op sportpark Zuilen. Die moeten verschillende soorten vogels, zoals spreeuwen en koolmezen, en vleermuizen aantrekken. De dieren eten insecten als muggen, kevers en engerlingen, die onder meer schade aan graswortels toebrengen.

Sparrowhawks seem significantly fewer in number this year

It’s been a year of mixed fortunes for Sparrowhawk (Accipiter nisus), with the highest recorded average counts in gardens in January 2016 followed by the lowest-ever numbers for December, as reported by the British Trust for Ornithology’s (BTO) Garden BirdWatch survey. Sparrowhawks are not always popular in gardens as they feed on other more popular garden birds. The species' population crashed in the 1950s and 1960s due to pesticide poisoning, but numbers have since recovered and they are the bird of prey most commonly seen in gardens.

Rückgang der Biomasse an Insekten ist Ursache für den Singvögelschwund

Die Zahl der Singvögel im Vogtland geht zurück. Das sagt Michael Thoß, Naturschützer und Ornithologe aus Auerbach. Damit bestätigt er Aussagen, die die Teilnehmer der Vogelhaus-Aktion von "Freie Presse" gemacht haben. Sie haben beobachtet, dass weniger Gäste an die Futterstellen fliegen. Ursachen für den fehlenden Flugbetrieb hat der Ornithologe mehrere ausgemacht: "Grünfinken sind seit zwei Jahren von einer Pilzkrankheit, dem Gelben Kropf oder Gelben Knopf betroffen, an der viele Tiere sterben." Die Pilzerkrankung zerfrisst die Rachenschleimhaut.

Black-Billed Magpie Decline in Nebraska

Many birders and bird-watchers in western and central Nebraska have noticed the unfortunate absence in recent years of a distinctive, entertaining and familiar bird species, the black-billed magpie (Pica hudsonia). In the late 1990s, black-billed magpies were found over most of the state, except the extreme east and southeast. They occurred as far east as western Lancaster and Saunders counties during that time. In other areas, especially the west, magpies were fairly common and could be reliably seen with little effort. Since about 2000, black-billed magpies have declined sharply.

Bird survey in University of Hyderabad records decline in number of bird species on campus

The spangled drongo was the rarest of the 93 species of birds spotted during the Great Backward Bird Count survey held in University of Hyderabad recently. Held jointly by international bird watchers Cornell Ornithology lab and Audubon, the survey was conducted between February 18-20. More than 25 student volunteers from UoH participated in the survey which was split into morning and evening sessions. The team covered over three fourth of the 1700-plus acre campus. Previously 109 bird species were spotted in the survery conducted in the campus.

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.

House sparrow population decline is caused by shortage of insect prey

Birds are the common denizens of the ecosystem and are considered as indicator species of ecosystem health. Various studies depicted the reduced teemingness of several bird species in most parts of the world. Among these birds, the house sparrow (Passer domesticus indicus) is the most familiar species which are co-evolved with man. The disappearance of sparrows has been widely reported from all over the world, including India too. Among Indian states, Kerala is also not an exception.

So wenige Vögel wie in diesem Winter hatten wir schon lange nicht mehr

Schon im Dezember gab es Hinweise darauf, dass die Anzahl der Vögel in den Gärten oder an Futterhäusern immer mehr abnimmt. Dass dort und in den Parks der Städte bisweilen Stille herrsche. Der Naturschutzbund Deutschland (Nabu) hatte die Botschaft damals versendet und gleich auch ein Angebot gemacht: Vom 6. bis 8. Januar hatten Vogelbeobachter zum siebten Mal die Möglichkeit, 60 Minuten lang die Vögel zu zählen, die sie beobachten konnten. Jetzt liegen die Ergebnisse der gemeldeten Daten der „Stunde der Wintervögel“ vor – und sie bestätigen im Februar den Trend vom Dezember.
