Rather than coming close to shore only to breed, James Cook University researchers found that female blacktip sharks remain in Cockle Bay, Australia, year-round with their young. This highlights the importance of conservation along coastal areas.
Massachusetts' State Department of Fisheries and Wildlife has proposed breeding 150 venomous timber rattlesnakes on a remote island to save the endangered species. What could possibly go wrong?
Reed warblers have set up a "neighborhood watch" to protect their nests from invasive cuckoos, who lay their eggs in local nests for others to raise. When reed warblers spot a cuckoo, they mob it and emit alarm calls that alert neighbors a cuckoo is at large and they should monitor their eggs closely. This has greatly benefited warblers, but cuckoo populations appear to be suffering.
Three adult piping plovers nested along New York's Lake Ontario shoreline for the first time in over 30 years. Among the birds was a breeding pair that successfully fledged a single chick – a promising step in the recovery of the endangered bird's Great Lakes population.
Following the arrival of gentoo penguins along the West Antarctic Peninsula, native Adelie penguins have experienced population declines. However, researchers are unsure whether increased food competition among the two species or climate change is ultimately to blame.
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 50-year study recently revealed that southern giant petrel seabirds living on the Antarctic island of Signy have experienced substantial population declines and reduced breeding success.
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.
The oldest known bird -- an albatross named Wisdom -- is about to lay another egg at 64 years old. Researchers believe she has raised as many as 36 chicks and clocked over six million ocean miles of flight time.
A new study suggests that Northern Gannets fly higher than thought during breeding season when they have to travel long distances for food and that 12 times as many of these birds than previously surmised could be killed by wind turbine blades.
