Populations of farmland birds are in freefall, down a staggering 55% in the last three decades

Farmland covers 45% of the EU’s land area and these habitats are rocketing towards biodiversity oblivion. We cannot afford to mince our words here, the situation is very serious and requires both monitoring and action. The European Bird Census Council (EBCC), where many BirdLife partners play a key role, has been coordinating the collation of data on more than 160 common bird species across 28 European countries. The data collected is fundamental to understanding the future of European biodiversity – and the forecasts are alarming.

Agricultural Intensification and Innate Immune Function in a Wild Bird Population

Agricultural intensification is an important anthropogenic perturbation of the environment. It is characterized by a specialization of the production process, which results in a switch from diverse plantations to large monocultures. Agricultural intensification is also associated with increased use of pesticides, harvest frequency, and density of plantations in cultivated areas. This type of practice is linked to the population decline of several bird species in Europe and North America.

Trends in the Lapwing population of North-Rhine – Westphalia 1850-2014

The population of Lapwing (Vanellus vanellus) in North-Rhine – Westphalia (NRW) has declined severely. Since the 1960s the species has lost an estimated 80% of its population, and from 2009-2014 the population has decreased by 40% resulting in a current population of a merely c. 12,000 pairs. Areas above 150m asl have been abandoned almost completely. The main reason for the severe declines lies in the agricultural intensification. This led to the loss of the original breeding sites until 1900. The secondary breeding sites, i.e.

Entwicklung der Kiebitzbestände in Nordrhein-Westfalen von 1850 bis 2014

Die Bestandsentwicklung des Kiebitzes ist in Nordrhein-Westfalen stark rückläufig. Schätzungsweise hat der Kiebitz (Vanellus vanellus) seit den 1960er Jahren 80 % des Bestandes eingebüßt, gesichert sind Verluste von 40 % zwischen 2009 und 2014, so dass der aktuelle Brutbestand nur noch ca. 12.000 Paare umfasst. Regionen in Höhen von mehr als 150 m ü. NN sind mittlerweile fast vollständig vom Kiebitz geräumt worden. Der Hauptgrund für die starken Rückgänge ist in der Intensivierung der landwirtschaftlichen Produktion zu sehen.

Agricultural intensification caused steep population decline of the Great Bustard in Iran

The current distribution and recent population trends of the Great Bustard ( Otis tarda ) in Iran were investigated based on a literature review and unpublished data (1995–2008) followed by three years of census (2009–2011) in areas where the species is still breeding. Results suggest that Great Bustards have disappeared from a large part of their former distribution in the country, including East Azarbayjan, Hamedan and Kurdistan provinces. The surviving groups are concentrated in West Azarbayjan where numbers are rapidly declining.

The Last of Guernsey's Meadow Pipits

Guernsey Post have annouced plans to issue a new stamp celebrating an endangered Bailiwick bird. The Meadow Pipit (Anthus pratensis), now classified as endangered in the Bailiwick of Guernsey, will feature on stamps as part of a collaboration with the WWF. Islanders may notice the new stamp on the front of their letters and parcels from the 15th February 2017. An attractive creature, the Meadow Pipit is a small, streaky, yellow-brown bird with pale legs, a long hind claw and white outer tail feather. It's high, piping call – a common upland sound – gives it its common name.

Kiebitze und Unken verschwinden im Rhein-Main-Gebiet

Als besonders bedrohlich erweist sich die immer intensivere Landwirtschaft. „Auf den Äckern und Wiesen stellen wir einen massiven Artenrückgang fest“, sagt NABU-Mitarbeiter Mark Harthun. Acker-Bodenbrüter wie Feldlerche (Alauda arvensis) und Kiebitz (Vanellus vanellus) gebe es in Hessen immer seltener. Auf den Äckern nisten die Tiere nicht, weil Jahr für Jahr in riesigen Mengen Pestizide gesprüht werden. Nicht nur wegen der Giftstoffe selbst, sondern auch weil die Getreide- und Grashalme durch das Düngen immer dichter wachsen, brüten dort kein Vögel mehr, wie es heißt.

Etwa 20 Vogelarten sind aus Hattingen verschwunden

Der Kuckucksruf erklang vor 20 Jahren häufig in Hattingen. „Den Kuckuck (Cuculus canorus) gibt es nicht mehr auf Hattinger Stadtgebiet“, sagt der Vogelexperte Thomas Griesohn-Pflieger . Seit 1994 beobachtet er die hiesige Vogelwelt. Die hat sich mit den Jahrzehnten stark verändert. Etwa 20 Vogelarten, die vor 20 Jahren noch da waren, gibt es nicht mehr. „Der Kuckuck ist beispielsweise ein guter Indikator für die Kleinvögeldichte, denn er braucht viele Kleinvögel, in deren Nester er seine Eier legen kann.

Burrowing owl population sees decline in Berkeley area

Fewer burrowing owls are returning to the Berkeley area as their population continues to dwindle, not only in California but across North America. Burrowing owls are small birds that live in burrows created by other animals. As a result of habitat loss in recent years, the California population of burrowing owls has declined, according to Scott Artis, the executive director of the Urban Bird Foundation. We’re going to wake up one day and see that we don’t have burrowing owls anymore,” he said. “(The cause is) really this loss of habitat.
