The United States and Canada are seeing a decline in their bird populations by over three billion, which is over 29 percent loss of bird population in North America. And the worst part is this has all happened in just the past 50 years, as per new research published by biologists and scientists looking into bird conservationist strategies.
Essentially we could say that the skies are being emptied out. The number of birds flying around North America is now at an all-time low, with it falling by 29 percent since 1970. If you had walked around the lands of the United States and Canada 50 years ago then you would have seen 2.9 billion more birds flapping around. The analysis and research have been published by the scientific journal Science, and it is the most intensive study yet to figure out what exactly is happening to our dwindling avian populations.
David Yarnold the president and chief executive of the National Audubon Society has announced that this publication is confirmation that the region has entered a full-blown crisis when it comes to keeping up bird populations. The truth is that experts have known for quite some time that birds were prime to be the next species on the extinction list. However, the new research is showing that the losses in the population are even happening amongst birds that are traditionally thought to have very strong populations such as robins or sparrows.
The main problem is habitat loss and the wide use of pesticides in farming. Common bird species are very vital when it comes to keeping our wider ecosystem alive and healthy, so this is an alarming study. Birds help control pests, pollinate flowers, spread seeds and even regenerate forests. As these birds die out and disappear, the habitats where they lived will not be the same. A big culprit is a pesticide known as a neonicotinoid, which causes birds to have difficulty putting on weight and delays their time of migration.
Another problem is that wider public opinion is not as interested in the sparrows or other little brown birds disappearing, the attention is focused on losses such as bald eagles, whereas the little birds dying out will have a much larger impact on the world.
