A legendary shorebird from Siberia to West Africa is giving warning signals in relation to the consequence of climate change to the planet. In a new research published in the Journal Science, an international team of scientists shows how the Arctic warming up produce drastic consequences on the decrease of the population of sub-species, red knot bird.

When the birds get to the tropical West Africa, their bills are just not enough to enable them to eat the best food, according to Discovery News. Scientists hope, though, that this phenomenon would pave the way for an understanding of the decrease of the birds that migrate.

Marcel Klaasen from the Center for Integrative Ecology, School of Life and Environmental Sciences, Deakin University gave his insights on the phenomenon of migration of birds. He said:

"We observed this in the red knot bird and found they are also starting to pay the price [of this body shrinkage] once they arrive in the tropical feeding grounds."

By utilizing satellite tools in the previous 33 years, researchers discovered snow in the high Arctic breeding grounds in the red knots start to exist earlier in time. Word has it that a rate about a half a day per year exists, as reported by the same publication.

The migration of birds from Siberia to West Africa refers to the birds' bodies going small by the day as they move from one place to another, according to Newsyac. Because the bodies get smaller as time goes by, the birds eventually stay still in one place as they lose the ability to move around eventually. The team gives complete details the ways the warming of the climate change of the Arctic could be liable for the population drops of a subspecies of red knot bird down the line.
