This week on 8 and 9 May we are celebrating World Migratory Bird Day (WMBD). This year's theme for the WMBD is Save migratory birds in crisis – every species counts! The aim of it is to raise the awareness of the man-made obstacles on the way of birds migrations.
The WMBD 2010 theme aims to raise awareness on globally threatened migratory birds, with a particular focus on those on the very edge of extinction – the Critically Endangered migratory birds. In line with the International Year of Biodiversity, the 2010 WMBD theme also highlights how migratory birds are part of the biological diversity of our world and how the threat of extinction faced by individual bird species is a reflection of the larger extinction crisis threatening other species and the natural diversity that underpins all life on earth.
A staggering 1,227, or 12,4% of the total 9,865 extant bird species in the world are currently classified as globally threatened and 192 of these are considered Critically Endangered on the IUCN Red List of threatened species, i.e. they face an extremely high risk of becoming extinct.
An estimated 19% of all known birds and about 30 of the 192 Critically Endangered bird species are considered to be migratory and undertake regular cyclical movements between their breeding and non-breeding areas.
By focusing on “migratory birds in crisis” during the International Year of Biodiversity, World Migratory Bird Day 2010 is also highlighting the role played by birds as indicators, enabling us to clearly see and highlight the negative effects our current way of life is having on the planet and it’s biodiversity.
Birds serve as vital indicators for the state of biodiversity and the biological health of the ecosystems they inhabit. If a bird species becomes threatened with extinction it is often a clear sign that the conditions of the required habitats have changed and that other species that depend on them may also be affected.
Migratory birds rely on several different habitats to survive – often across several continents. They need areas to breed, rest, feed and to raise their young. The conservation of migratory birds depends to a large extent on the conservation of their habitats, thereby simultaneously benefiting other species.
