Hilarious article in the Daily Mail which reports research on bustards showing that
indulging in overt sexual behaviour could lead to premature ageing in men through 'burnout', according to scientists studying fertility patterns in birds.
A 10-year research programme into the sex lives of bustards, birds with a very flamboyant mating display, showed a dramatic decline in the quality of sperm among the more 'showy' males.
The mating display of the male Houbara bustard, known as 'booming', sees striking ornamental feathers flare up before the bird runs around while making a low-pitched call.
The males can 'boom' for as much as 18 hours a day, six months of the year.
Dr Preston, who is based at the University of Burgundy in France, led his team in measuring the length of time each male spent 'booming', and then compared that with changes in fertility, which is usually associated with ageing.
The more time the birds spent 'booming', the more dramatic was the decline in their fertility.
