 | A new analysis indicates that birds don't fly alone when migrating at night. Some birds, at least, keep together on their migratory journeys, flying in tandem even when they are 200 meters or more apart. ...> Full Article |
Many birds are arriving earlier each spring as temperatures warm along the East Coast of the United States. However, the farther those birds journey, the less likely they are to keep pace with the rapidly changing climate.

 | Take a deer's body, attach a camel's head and add a Jimmy Durante nose, and you have a saiga - the odd-ball antelope with the enormous schnoz that lives on the isolated steppes of Central Asia.

 | How young migrating birds choose the nesting location of their first breeding season has been something of a mystery in the bird world. But a new study of the American redstart by the University of Maryland and Smithsonian Migratory Bird Center of the National Zoo suggests that the environmental conditions the birds face in their first year may help determine where they breed for the rest of their lives, a factor that could significantly affect the population as climate change makes their winter habitats hotter and drier. ...> Full Article |
 | Since its discovery, the annual migration of eastern North American monarch butterflies has captivated the human imagination and spirit. That millions of butterflies annually fly a few thousand miles to reach a cluster of pine groves in central Mexico comprising just 70 square miles is, for many, an awesome and mysterious occurrence. However, over the past two decades, scientists have begun to unveil the journey for what it is: a spectacular result of biology, driven by an intricate molecular mechanism in a tiny cluster of cells in the butterfly brain. ...> Full Article |
 | 38-year-old researcher Kasper Thorup, University of Copenhagen, has come a step closer to unravelling the secret of how migration birds navigate across large distances. He has followed the birds' passage across USA from small sports planes. The results are now being published in the scientific journal PNAS. ...> Full Article |
