The biggest changes in bird’s wing length have occurred since the 1970s, and all this is due to the fact that climate changes that the planet constantly crosses over time.
The wings of some common Western Australian birds have grown four to five centimeters in the last 45 years and the cause seems to be directly related to climate change, according to an Australian study released earlier this week.
Scientists at the University of Notre Dame in Sydney have linked the growth of Barnard’s parrots (Barnardius zonarius) with climate change, given that generally the extremities of animals living in hot climates tend to be longer.
“As temperatures rise, increasing wing lengths can help these birds get rid of excess heat and adapt better to their environment,” explained one of the scientists who participated in the study, Dylan Korczynskyj, statements quoted by the local ABC station.
Korczynskyj also explained that major changes in wing length occurred from the 1970s, a period coinciding with temperature variations of about 0.1 and 0.2 degrees Celsius, and deforestation Registered in the state of Western Australia.
Planet Earth has been undergoing varying climatic changes over the years and it has been proven that this factor influences the evolution of species that are “forced” to adapt to the conditions and life that the places from which they originate, offer them.
Although the temperature variation seems minimal, the impact on the environment is significant, as the research shows the parrots, according to the scientist.
In this investigation, there were examined several species of the Museum of Western Australia which has a collection of birds dating to the early nineteenth century and also includes a copy of a Barnard parrot of 1904.
