1 op 8 vogels wereldwijd met uitsterven bedreigd

Bijna 1.500 vogelsoorten of één op acht vogels wereldwijd zijn met uitsterven bedreigd. Daarnaast neemt bij 40 procent van de 11.000 vogelsoorten de populatie af. Dat blijkt uit een nieuw rapport van BirdLife, een internationale koepel van natuurorganisaties. “De gezondheid van de vogelpopulaties is een goede maatstaf voor de staat van de ecosystemen”, zo klinkt het. BirdLife maakt jaarlijks de balans op van het wereldwijde vogelbestand.

Agricultural intensification threatens 74% of the 1,469 bird species globally at risk of extinction

One in eight bird species is threatened with global extinction, and once widespread creatures such as the puffin, snowy owl and turtle dove are plummeting towards oblivion, according to the definitive study of global bird populations. The State of the World’s Birds, a five-year compendium of population data from the best-studied group of animals on the planet, reveals a biodiversity crisis driven by the expansion and intensification of agriculture. In all, 74% of 1,469 globally threatened birds are affected primarily by farming.

Without Birds, Lizards, and Other Vertebrate Pollinators, Plant Reproduction Could Decline by Two-Thirds

Bees tend to get the most attention as pollinators critical to the survival of plant species. But lizards, mice, bats, and other vertebrates also act as important pollinators. A new study finds that fruit and seed production drops an average 63 percent when vertebrates, but not insects, are kept away from plants.

Michael McCarthy: We’ve lost half our wildlife. Now’s the time to shout about it

Most Britons remain blithely unaware that since the Beatles broke up, we have wiped out half our wildlife. Yet we are not alone. Last week, the French woke up in a dramatic way to the fact that their own farmland birds, their skylarks and partridges and meadow pipits, were rapidly disappearing: Le Monde, the most sober of national journals, splashed the fact across the top of its front page.

EU in 'state of denial' over destructive impact of farming on wildlife

Europe’s crisis of collapsing bird and insect numbers will worsen further over the next decade because the EU is in a “state of denial” over destructive farming practices, environmental groups are warning. European agriculture ministers are pushing for a new common agriculture policy (CAP) from 2021 to 2028 which maintains generous subsidies for big farmers and ineffectual or even “fake” environmental or “greening” measures, they say.

Balochistan witnesses steep decline in bird populations

There has been a steep decline in bird populations in Balochistan (one of the four provinces of Pakistan. Its provincial capital and largest city is Quetta), said conservator of forests and wildlife Balochistan Sharifuddin on Wednesday. The official confirmed that there has been a decline in the overall population of sparrows among other birds in Quetta and other parts of Balochistan. The revelation comes just a day after bird lovers marked the World Sparrow Day on Tuesday (March 20). “Even crow, which was a common bird, has decreased in number,” he remarked.

Fluitende vogeltjes zijn binnenkort verleden tijd

De lente is begonnen, en dan hoor je buiten steeds meer vogeltjes fluiten en zingen. Maar dat is voor toekomstige generaties misschien iets wat ze nooit meer zullen horen. In West-Europese landbouwgebieden gaat het aantal typische vogels, zoals de leeuwerik en de vink, drastisch achteruit. Dat stellen wetenschappers van het Centre National de la Recherche Scientifique (CNRS) en het Muséum National d’Histoire Naturelle in Frankrijk.

Catastrophe as France's bird population collapses due to pesticides

Bird populations across the French countryside have fallen by a third over the last fifteen years, 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.

Les oiseaux disparaissent des campagnes françaises à une « vitesse vertigineuse »

Ce déclin « catastrophique », d’un tiers en quinze ans, est largement dû aux pratiques agricoles, selon les études du CNRS et du Muséum d’histoire naturelle. Le printemps risque fort d’être silencieux. Le Muséum national d’histoire naturelle (MNHN) et le Centre national de la recherche scientifique (CNRS) publient, mardi 20 mars, les résultats principaux de deux réseaux de suivi des oiseaux sur le territoire français et évoquent un phénomène de « disparition massive », « proche de la catastrophe écologique ».

Bug diet of birds has dramatically declined in quality, researchers find

"You are what you eat" is the guiding principle behind a new study comparing the diet of birds today with that of birds dead for more than a century. The results show large changes in the diets of aerial insectivores, or birds such as swallows, swifts, martins and whip-poor-wills that consume insects while in mid-flight. Today, the bulk of the birds' diet is made up of small insects at the lower end of the food web, or at a lower "trophic" level, the researchers say.
