Budgies Also Yawn (contagiously)

The 2011 Ig Nobel Physiology Prize was awarded to Anna Wilkinson (of the UK), Natalie Sebanz (of The Netherlands, Hungary, and Austria), Isabella Mandl (of Austria) and Ludwig Huber (of Austria) for their study “No Evidence of Contagious Yawning in the Red-Footed Tortoise.” However, although Red-Footed Tortoises don’t seem to contagiously yawn, many other animals […]

Budgerigarian Contagious Yawning (quite untortoisean!)

Although scientists have failed to find evidence of contagious yawning in tortoises (though those scientists succeeded in winning an Ig Nobel Prize), other scientists have now found evidence, they say, of contagious yawning in budgies [a non-yawning specimen of which is pictured here in a photo by Elektrofisch]. They published a study about it: “Evidence for […]

On Contagious Yawning in the Red-Footed Tortoise

Scientists know a bit more about contagious yawning – one of science’s utter mysteries – than they did a year ago, thanks to a study called No Evidence of Contagious Yawning in the Red-Footed Tortoise,Geochelone carbonaria. The study’s authors say their experiments, conducted with seven tortoises, might help eliminate some of the many competing theories as […]
