While the early bird might catch the worm, it's the quick bird that lands the ladies, according to new research into the running performance of an Arctic cousin of the grouse. Scientists studying rock ptarmigan on the Norwegian archipelago of Svalbard discovered a large difference in the running capabilities between the sexes, with the larger males able to run more efficiently and up to 50% faster than females. The University of Manchester team suggested that faster, efficient male birds are...

Researchers report that an arctic relative of the grouse has evolved to cope with its extreme environment by moving efficiently at high speeds or when carrying winter weight. This discovery is of relevance to welfare in the poultry industry where birds are bred to be heavier. Ultimately better understanding the physiology of a natural animal model of extreme weight gain could one day lead to improving the welfare and meat yield of domesticated breeds and so contribute to preventing a future...

Researchers from the Center for Ecological Research and Forestry Applications (CREAF) and the Autonomous University of Barcelona (UAB) have demonstrated, using a map of the potential distribution, the alpine marmot's capacity for adaptation in the fields of the Pyrenees. Its quick proliferation makes it a successful example of species introduction. At the end of the Pleistocene (10,000 years ago), the increase in temperatures brought an end to the alpine marmot (Marmota marmota) in the...

The Ptarmigan (Lagopus mutus) is a small (31-35 cm) bird in the grouse family. It is an inactive species, breeding across subartic Eurasia on rocky mountainsides and tundra. There are isolated populations in the Pyrenees, the Alps and the mountains of Scotland. It also occurs in Alaska, and northern Canada, where it is called the Rock Ptarmigan, or colloquially as Snow Chicken. This is the official bird for the territory of Nunavut, Canada. The Eurasian spring male has greyish...
