Birds fly faster due to climate change

Not only that, they also gain weight, improve fertility from changes in wind speed.

>>>Seagull is the rarest in the world

The speed of wind traveling across Antarctic waters has increased over the past three decades, and the increasingly strong winds have forced the region's birds to fly faster, according to new research by French experts. Science . The change in wind speed is related to climate change, and the latest influence of this process, only in the present time, is thought to be quite positive for many birds. Their feeding routes are shortened, increased fertility, and even more individual birds increase by more than 1kg on average in only about 30 years.

The object of the study is the large seagulls, birds spend most of their time flying around, and they only land on the ground to find food or reproduce. The Antarctic Crozet Islands have become their homes for years. The research team thought that other birds, like black seagulls, were also affected by such changes as large wild seagulls. The group of Henri Weimerskirch, of the Chize Biological Research Center (France), chose the Crozet archipelago to study because it recorded enough parameters for many years, from the climate to the bird community.

Seagulls are fatter and fly faster than before

Weimerskirch and colleagues analyzed information for 40 years about the large seagull population at Crozet. Since 1989, they have started to install satellite signal transmitters to closely monitor the flight path of birds here. Therefore, Weimerskirch's team has determined that the rate of west wind in Antarctic sea has increased by an average of 15% in just a few decades. The result is the flight path of the large, enlarged albatross. If the female fly averages 500 km / day in 1990, this number increases to 700 km / day in 2010.

The bird currently seems to benefit from the change in wind speed, but this positive effect may only exist in the short term if winds in the Antarctic sea follow the speculative path of science. Based on the calculation models, Weimerskirch said that the wind will become stronger and stronger, and the change of wind direction towards the polarity will be stronger. This can put pressure on the local bird communities, altering their feeding routes.
