Light guides flight of migratory birds
...80s, he was doing research to determine how homing pigeons
navigated. There was a theory that wind-borne odors provide pigeons
with information about the locations of odor sources, which could then be used to determine their po...
Pigeons provide clue to solving common problem in heart patients
Through studying pigeons
with genetic heart disease, researchers at Wake Fo...archers sought to find the answer in two breeds of pigeons

Animal brains 'hard-wired' to recognize predator's foot movements, Queen's study suggests
...isplay the electronically captured motion of cats, pigeons
and humans. People were tested on whether they could tell the direction of movement when these cues were changed. Scrambling the dots didn't create a problem, but when the image was inverted, observers were unable to say if the animal was moving to...
Bacteria which sense the Earth's magnetic field
...certain animals -- like migratory salmon or homing pigeons
-- have magnetite crystal chains in particular tissue. These chains are astoundingly similar to those in bacteria, and possibly develop through a related mechanism. ...
The lopsided brain: Attention bias is shared by humans and birds
...at the midline of the search area, both chicks and pigeons
showed a considerable leftward bias in pecking. The experiment is similar in concept to those that reveal pseudoneglect in humans--so-called cancellation tasks in which subjects are asked to "cancel-out" evenly distributed visual targets on a sheet o...
The secret lives of whales

in a park except that in Smith’s case, they tow a dead whale out to the deep sea, place a transponder on it, and drop it to the sea floor. The transponder lets them find it later with a manned submersible or robotic vehicle. They now know that a wha...
