 | 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.

 | Some migratory songbirds figure out the best place to live by eavesdropping on the singing of others that successfully have had baby birds - a communication and behavioral trait so strong that researchers playing recorded songs induced them to nest in places they otherwise would have avoided. ...> Full Article |

 | Research led by Dr Melanie Massaro and Dr Jim Briskie (Biological Sciences) showing that the New Zealand bellbird is capable of changing its nesting behaviour to protect itself from predators, may be good news for island birds around the world at risk of extinction. ...> Full Article |

 | In the world of birds, where fancy can be as fleeting as flight, the color of the bird apparently has a profound effect on more than just its image. A new study of barn swallows reveals it also affects the bird's physiology. ...> Full Article |

Scientists have synthesized and studied a sophisticated molecule that, under illumination, is sensitive to both the magnitude and the direction of magnetic fields as tiny as the Earth's, which is, on average, one-twenty thousandth as strong as a refrigerator magnet.

 | Male songbirds produce a subtly different tune when they are courting a female than when they are singing on their own. Now, new research offers a window into the effect this has on females, showing they have an ear for detail. The finding provides insights not only into the intricacies of songbird attraction and devotion but also into the way in which the brain develops and responds to social cues, in birds - and humans. ...> Full Article |
 | The announcement of the discovery of a new bird comes with a twist: It's a white-eye, but its eye isn't white. Still, what this new bird lacks in literal qualities it makes up for as one of the surprises that nature still has tucked away in little-explored corners of the world. ...> Full Article |

 | The first study of how individual wandering albatrosses find food shows that the birds rely heavily on their sense of smell. The birds can pick up a scent from several miles away, U.S. and French researchers have found. ...> Full Article |

 | Seabird colonies on islands are highly vulnerable to introduced rats, which find the ground-nesting birds to be easy prey. But the ecological impacts of rats on islands extend far beyond seabird nesting colonies, according to a new study by researchers at the University of California, Santa Cruz. ...> Full Article |
 | 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 |
 | The beeps, chirps and whistles made by some hummingbirds and thought to be vocal are actually created by the birds' tail feathers, according to a study by two students at the University of California, Berkeley. ...> Full Article |

 | Swedish researchers report that birds captured in the hyperboreal tundra, in connection with the tundra expedition "Beringia 2005," were carriers of antibiotics-resistant bacteria. These findings indicate that resistance to antibiotics has spread into nature, which is an alarming prospect for future health care. ...> Full Article |
 | With the aid of various alarm calls the Siberian jay bird species tells other members of its group what their main predators-hawks-are doing. The alarm calls are sufficient for Siberian jays to evince situation-specific fleeing behaviors, which enhances their chances of survival. This discovery, being published by Uppsala University researcher Michael Griesser in the journal Current Biology, shows for the first time that animals can assess and communicate about the behavior of predators. ...> 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 |
 | Scientists from the University of Exeter have shown that birds with higher stress levels adopt bolder behaviour than their normally more relaxed peers in stressful situations. The research team studied zebra finches, which had been selectively bred to produce three distinct types - 'laid-back', 'normal' and 'stressed' - based on their levels of stress hormone. The group was surprised to find that the 'stressed' birds were bolder and took more risks in a new environment than the group that was usually more laid-back. Their findings are published today (26 October) in the journal Hormones and Behaviour. ...> Full Article |
 | The ability to ramp up testosterone production appears to drive male dark-eyed juncos to find and win mates, but it comes with an evolutionary cost. Big fluctuations in testosterone may also cause males to lose interest in parenting their own young, scientists have learned. ...> Full Article |
