Who's a fat boy then?

Me, I blame the parents. That and the television. Oh and the absence of diet Trill. The Independent reports:

Increasing numbers of budgerigars are becoming fat to the point of obesity, scientists say, because of high-energy diets, lack of exercise and their refusal to fly.
Researchers at the universities of Gröningen and Bern filmed large numbers of the caged birds and found that they were so lazy that they walked to their food rather than flying.

Hey, if you were stuck in a wee cage most of the day, you'd have trouble flying.

And, btw, have university researchers not got anything better to do?
