More Than a Third of the North America’s Bird Population Is Gone
Three billion birds vanished from North America’s skies since 1970 according to a new statistical study. This number constitutes one-third of the whole bird population which are breeding, living, and flying across the North American continent.
Vanished birds are representatives of the most common and familiar to us bird species such as sparrows, pigeons, woodpeckers, crows, and finches. Ken Rosenberg, senior research officer of the Cornell ornithology laboratory, says that numerous statistical data reveal the mass extinction of bird species across the globe.
The North American continent which agricultural and urban areas took most of the territory is the most severely affected in terms of the decreasing number of birds.
The most disturbing aspect which these statistical studies have revealed lies in the constant decrease of the population of the most widespread bird species, not only the endangered ones. Well-known pigeons, sparrows, finches, the forties, and crows are disappearing across the whole continent.
Bird species are in great danger
Endangered bird species are in greater danger than ever and now the most ordinary birds are in danger too. Birds are orderlies of the environment and such a population’s shortening demonstrates the lack of biodiversity and the critical state of North American nature.
The most affected bird species include birds that inhabit prairie, lawn, and wide-open areas. Expanding agricultural lands, farming, and land cultivation rapidly reduce their habitat area.
Extensive use of pesticides causes massive extinction of insects which leads to the starvation death of millions of birds. Farming machines, tractors, sowers, and harvesters devastate the bird’s nests and habitat areas.
Birds play an irreplaceable role in the life of the environment. They pollinate plants, control the level of harmful insects, and are one of the most important links in the food chain.
Not all bird species experience the same population catastrophe. Aquatic birds such as gooses, ducks, and swans have increased their population in recent decades. Such change became possible due to the strict government legislation which was developed in order to protect endangered aquatic bird species and extensive funding from the budget.
Effective and immediate protective measures can stop the reduction of the bird population and save many endangered species. Rational and environmentally-sustainable farming could save vast habitat areas of our feathered friends.
