Higher Wind Pace Surges Birds’ Speed

Higher Wind Pace Surges Birds’ Speed

A team of scientists in Europe has found that stronger winds in the Southern Ocean around Antarctica have been blowing at a faster pace and have been increasing the rate of speed of the Albatrosses, reports reveal. They are found to have been flying fast.

Henri Weimerskirch and colleagues at the Centred' Etudes Biologiques de Chize in Villiers en Bois, France, conducted a study and collected the data on population of albatrosses on Windy Crozet Islands over the past few decades. To track the birds’ movements, the team of scientists fitted the wind riders, snow-coloured, with wingspans of living birds together with satellite transmitters.

After the study, they came with the conclusion that there was an increase in the wind speed with the increase in atmospheric pressure across the western Indian Ocean where albatrosses are found, said the reports. Along with this, there was a corresponding reaction of birds to the greater wind speed. They were found to have grown fatter by one kilogram on an average, flying faster as well as taking less time in hunting of food and having more babies.

After noticing the changes over 1990s, Scott Shaffer, an Assistant Professor of biology at San Jose State University, added to the context, "This is one of the most surprising aspects of the study and is consistent with the changes in wind patterns because wind is everything to these birds and body mass changes influence their flight performance".

Although benefits have been realized due to strong blowing of the winds but the study warns uniformly that if earth keeps on warming and wind blows more rapidly, these benefits may be very momentary and short term.
