Cambodia records 50 percent decline in vulture population in a decade

Cambodia's vultures are facing a high risk of extinction and have seen a 50 percent decline in number since 2003, conservationist groups said in a joint statement on Monday. "Only 121 of the birds were recorded in this year's national census, the lowest number on record since 2003," said the joint statement released by Wildlife Conservation Society (WCS), BirdLife International, World Wide Fund for Nature (WWF), and Angkor Center for Conservation of Biodiversity. "Recent reviews indicate that poisoning is the major threat to the vulture population in Cambodia," the statement said.

Perplexing decline in the American kestrel population is related to lack of prey

Not so long ago, on a drive down a rural road in Minnesota you’d often see an American kestrel (Falco sparverius) perched on a power line, watching for a dragonfly or small rodent to pass beneath. If you were really lucky, you’d spot this smallest member of the falcon family flapping its wings in its unusual hovering flight as it watched for prey. Such sights are becoming increasingly rare. These handsome little raptors, about the size of a mourning dove, are suffering a long-term and widespread population decline.

The iconic hen harrier is on the brink of extinction in the British Isles

The RSPB has flagged up concerns about the decline of hen harriers (Circus cyaneus) in Northern Ireland, with just 46 breeding pairs left in the region, a fall of 22 per cent since 2010 when there were 59. According to BirdWatch Ireland in 2015 there were an estimated 108-157 breeding pairs in the Republic, a decline of 8.7 per cent since a 2010 survey which recorded 128-172 pairs.

Insektensterben muss gestoppt werden

Es kann keinen Zweifel mehr geben, dass das „Insektensterben“ von großer Tragweite ist, für die Landwirtschaft, für die Ökosysteme und die Biodiversität im Land, und nicht zuletzt für alle, die sich einen Frühling ohne Schmetterlinge nicht vorstellen können. Fakt ist ein Rückgang von Insekten und insektenfressenden Wirbeltieren in Deutschland. Als Hauptgrund für dieses „Verschwinden“ wird jeweils der Einsatz von systemischen Insektiziden vermutet. Diese Stoffe wirken auf das Nervensystem und somit auf den Orientierungssinn und das Verhalten von Insekten und anderen Gliedertieren.

Main-Taunus-Kreis ist Hochburg sterbender Vögel

Bei uns im Vorgarten liegt eine tote Eule“, wandte sich vor ein paar Tagen ein Anwohner der Wilhelm-Dienst-Straße in Flörsheim an Bernd Zürn vom BUND. Der war sich ziemlich sicher: Das tote Tier war eine Waldohreule (Asio otus). Als Todesursache vermutet Zürn eine klaffende frische Wunde neben dem Schnabel. Das Tier lag unter einem hohen und sehr dicht beasteten Nadelbaum, den die Eulen gern als Schlafplatz nutzen. Die ungewöhnlich große Menge an Gewölle, den ausgewürgten Speiseresten, die unter dem Baum lag, überraschte sogar Bernd Zürn.

Hen harrier driven to extinction in Northern Ireland

There are now 46 breeding pairs left in Northern Ireland, a fall of 22% since 2010, when there were 59 pairs, and the numbers are also declining elsewhere in the UK, the Royal Society for the Protection of Birds (RSPB) reports. The hen harrier (Circus cyaneus) population has suffered a decline of 88 pairs (13%) over the past six years with a total UK population estimated to be 545 pairs, according to the latest figures from the fifth national hen harrier survey. Known for their majestic skydancing ritual, this graceful bird is one of the most threatened birds of prey in the UK.

Hen harrier plunges towards extinction in England

The hen harrier (Circus cyaneus), an iconic bird of prey, is heading towards the brink of extinction in England, new figures suggest. There are just four breeding pairs left in England and numbers are declining elsewhere in the UK. Scotland is the traditional stronghold of these raptors, but numbers have fallen 9% since 2010. Numbers in England fell from twelve pairs in 2010 to just four in 2016.

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.

Sparrowhawks absent from gardens this winter

Sparrowhawks are most frequently seen in gardens during the autumn and winter months, a time when numbers are swelled with juveniles and when the smaller birds they prey on are flocking into gardens to feed. January 2016 saw the highest average counts of Sparrowhawk (Accipiter nisus) for the time of year but since summer 2016 numbers have been abnormally low, according to Garden BirdWatch. They were only seen in 8% of gardens in December, well below average and a 5% reduction on December 2015. Sparrowhawks are not always popular garden visitors, as they feed on other garden birds.
