The flight speed of birds is more complex than previously thought

The flight speed of birds is more complex than research has previously managed to show. In a new study from Lund University in Sweden, researchers have found that birds use multiple – each one simple yet effective—methods ...

Crested pigeons use feathers to sound the alarm

Many animals will sound an alarm to alert other members of their group of impending danger. Now, researchers reporting in Current Biology on November 9 have shown that crested pigeons do this in a surprisingly non-vocal way. ...

Even light oiling is like flying with a ball and chain for birds

The wind rushing between skyscrapers is a substantial hurdle for anyone interested in operating small drones in urban areas. Yet, pigeons seem to have little trouble maneuvering through turbulent city skies. With sights set ...

Birds fly faster in large flocks

New research at Lund University in Sweden shows that the flight speed of birds is determined by a variety of factors. Among the most sensational is that the size of the flock has a significant impact on how fast the birds ...

Researchers examine the evolution of flight

Research by post-doctoral fellow Alexander Dececchi challenges long-held hypotheses about how flight first developed in birds. Furthermore, his findings raise the question of why certain species developed wings long before ...

Budgies found to fly at just two speeds

(Phys.org)—A pair of researchers has found that at least one type of birds flies at just two speed levels. In their paper published in the journal Biology Letters, Ingo Schiffner and Mandyam Srinivasan with the University ...
