A new report by North American Bird Conservation Initiative stated that a third of North America’s migratory birds are facing extinction because of several harmful environmental factors including climate change. Some other factors are the rising sea-level, land development and oil spills.
The report has been made public on May 18. It said that 350 species of migratory birds across North America are on the verge of extinction. The report incorporates a section called the Species Assessment Summary and Watch List. It includes 1154 local species from Canada, US and Mexico. They are ranked according to the level of concern, reported abc News.
The report assigns each species a concern score between 1 and 20. The species which ranked 14 or higher were in the report’s watch list of endangered species and those which have scored 13 are rapidly declining. There are some species which have even scored 20. The California condor, the imperial woodpecker, and the Florida scrub-jay are among such birds, according to the Scientific American report.
It revealed that there are 432 species with concern score of 14 or even higher. These species have a steeply declining population trend. They are at the risk of extinction but till now very minimal action has been taken for the conservation or to reduce the threat.
Christian Artuso, who is a Bird Studies Canada biologist, said that these migratory birds are linked between nations and that itself calls for a joint effort towards the preservation of them. She urged all nations to shoulder the responsibility to bring biodiversity back before it becomes too late, reported Tech Times.
However, the situation is far worse than it has been reflected in the report as it has excluded the Caribbean and Central American countries except Mexico. It also has not included regions that are in the US but not part of North America. Two such regions are Hawaii and Guam and bird species extinction rate is extremely high there.
