Woodland birds

The population of lesser spotted woodpeckers has almost halved since 2009

The population of lesser spotted woodpeckers (Dryobates minor synon. Dendrocopos minor) has almost halved since 2009 because dead trees are being quickly removed from parks and woods, the British Trust for Ornithology said. The sparrow-sized birds have been declining since about 1980 and only about 2000 remain. The birds tend to nest in decaying wood because it is softer and therefore easier for them to peck when carving a nesting hole.

Stille ramp: de insecten verdwijnen

Er zijn steeds minder insecten. Uit onderzoek blijkt dat de hoeveelheid insecten in de natuurgebieden rond het Duitse Krefeld met bijna 80% is afgenomen in 25 jaar van 1989 tot 2014. Een afname die volgens een publicatie in Science niet alleen in Duitsland geconstateerd wordt, maar ook in andere landen. Zo daalde het aantal insecten in Schotland met 60%. Het onderzoek in Krefeld werd uitgevoerd in natuurgebieden waar niet zo extreem veel was veranderd in het beheer van die gebieden zelf. Maar in de omgeving is wel veel veranderd.

British wildlife is in serious trouble

Populations of farmland, woodland and marine birds have all fallen dramatically over the past 50 years, according to new government figures. In all bird species, populations have declined by six per cent since 1970, but some species saw stunning declines over the past five decades, as pesticides, the intensification of farming and the removal of hedgerows wreaked havoc. Bird populations are seen as a key indicator of the health of the natural world as they tend to feed on small insects that are the basis of the food chain.

Bird decline in Bulgaria after the country joined the EU in 2007

Based on monitoring data for the period 2005-2010, we studied the trends in abundance and species richness of common breeding birds in Bulgaria before and after the country joined the EU in 2007. We analysed the trends in birds of farmland, woodland and “other” habitats, and additionally, we tested whether indices of the commonest birds are representative of wider changes in bird populations. At species level (n = 32), significant declines were detected in 11 species (34%), and increases in just two (6%); 19 species (60%) had uncertain trends.

Global population decline in the Rustic Bunting

To assess the Rustic Bunting’s global conservation status we compiled, for the first time, population data across its breeding and wintering ranges. The analysis reveals a 75–87% decline in overall population size over the last 30 years and a 32–91% decline over the last 10 years. The trend estimates indicate that the long-term (30-year) range-wide population decline in the Rustic Bunting is of similar magnitude to two well-known examples of declining species within the same genus, the Yellow-breasted Bunting Emberiza aureola and the Ortolan Bunting E. hortulana.

West Kalimantan’s storm’s stork at risk of extinction

The Storm's stork (Ciconia stormi) is a medium-sized stork species that occurs primarily in lowland tropical forests of Indonesia, Malaysia and southern Thailand. A recent survey conducted along the coastal areas of Kubu, West Kalimantan, shows an alarming rate of population decline among this local bird, raising concerns about the condition of the local mangrove forest ecosystem. The bird, found throughout Borneo, was classified as critically endangered by the International Union for Conservation of Nature in 1994.

Bird Population Faces Crisis In The Vermont Forest

Vermont is famous for its natural and mesmerizing landscape that includes a big forest. Unfortunately, a recent report has revealed the decrement of the bird population there. ABC News reported a sharp decline of 14.2 percent in the bird population over the last 25 years in the Vermont forest. The latest study has unveiled this crucial fact. Several rare and common bird species exist in the said forest. Among them, some species solely depend on the flying insects and they form a major portion of the bird population.

Dramatic decline of aerial insectivores in Vermont

Fewer birds appear to live in Vermont today than 25 years ago, according to recent research by the Vermont Center for Ecostudies. The most dramatic declines in bird populations were seen among those that live off flying insects, scientists say. Known as aerial insectivores, this diverse group of birds has declined 45 percent in Vermont, according to the study.

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.

Assam's white-winged wood duck is threatened

“I am Assam’s State bird Deo hah. My current status is threatened. Please do not kill us, nor collect our ducklings or eggs” – reads a new campaign poster of wildlife NGO Aaranyak, starkly describing the current status of the State bird, the white-winged wood duck (Asarcornis scutulata). As the rhino continues to be the focus of wildlife conservation in the State, the numbers of the white-winged wood duck are dwindling slowly and silently with little or no attention coming from the State Government.
