A monarch butterfly's wing patterns may ultimately provide clues as to where it was born. This could help researchers learn more about the iconic creatures' annual migration.
Storks and other European birds have been cutting their annual migrations to Africa short by stopping to feed at nearby landfills. Researchers say consuming "junk food" is unhealthy, and when the birds alter their travel plans they disrupt ecosystems both at home and at their winter destinations.
Darkness blankets the icy north in the winter, but tiny Arctic marine creatures are guided by the light of the moon. Researchers say the creatures' regular vertical migrations could help store more carbon deep in the ocean.
Humpback whales are spending some extra time up north in Alaska this season. Experts say the whales are slow to arrive at breeding grounds in Hawaii because of possible food competition or El Niño disruptions.
A combination of satellite data and chemical tests reveal a more accurate picture of where Barn Swallows migrate in the winter.
New computer models suggest over 320,000 juvenile sea turtles from populations throughout the Atlantic Ocean were largely impacted by the 87-day oil spill in the northern Gulf of Mexico.
Volunteers with the Massachusetts Audubon Society have rescued nearly 120 "cold-stunned" sea turtles from shores of Cape Cod Bay. Researchers at the New England Aquarium will spend the next few days slowly warming the animals to get their body temperatures back to normal.
More than 90 percent of the world's migrating birds suffer from habitat loss along their long and remarkable journeys, so researchers are calling for increased collaborative and international efforts.
Painted bunting has come to vacation at Prospect Park in Brooklyn, N.Y. Not only is the male bird out of its natural range, but it is out of season -- right about now he should be basking in the Florida sun.
Long seasonal migrations can lower parasite prevalence North American monarch butterflies since the journeys ultimately put a greater distance between uninfected and infected individuals.
Army ants link up to create living bridges use to overcome gaps and obstacles they encounter along forest floors. These structures were thought to be static, but a study featuring time-lapse film has revealed that they are highly dynamic and responsive.
Cuckoos are migratory birds that use a complex decision-making process to find their way to their summer homes, even without the guidance of a sibling or biological parent.
Having rebounded from near-extinction, whooping cranes remain a top priority for conservationists. That's why the Father Hupp Wildlife Management Area in Thayer County, Nebraska, decided to temporarily close when six whooping cranes made a pit stop in the area during their migration.
The ancestry of modern Europeans' genetic make up has become somewhat clearer with the discovery of a previously unknown "fourth strand" of ancient hunter-gatherer ancestry.
