MICE WHISTLE LIKE A JET ENGINE TO ATTRACT A MATE

Mice make whistling noises to seek sex by using a mechanism similar to that of a jet engine inside their throats, research has found.

It was previously thought that these ‘Clangers’-style songs were either the result of a mechanism similar to that of a tea kettle, or of the resonance caused by the vibration of the vocal cords.

But a study co-authored at the University of Cambridge and published in the journal Current Biology has found that when mice ‘sing’, they use a mechanism similar to that seen in the engines of supersonic jets.

The high frequency whistles are used by mice to attract mates and for territorial defence.

“Mice make ultrasound in a way never found before in any animal,” said the study’s lead author Elena Mahrt, from Washington State University.

The researchers found that mice do not use vibrating vocal folds in their larynx to make their ultrasonic sounds.

Instead, they point a small air jet coming from the windpipe against the inner wall of the larynx, causing a resonance and producing an ultrasonic whistle.

Using ultra-high-speed video of 100,000 frames per second the researchers showed that the vocal folds remain completely still while ultrasound was coming from the mouse’s larynx.

“This mechanism is known only to produce sound in supersonic flow applications, such as -read more

Osprey nesting tower erected in Yelland

AN OSPREY nesting platform is to be put up overlooking the Yelland estuary so the rare birds can be spotted during their bi-annual migrations.

There are only thought to be around 200 breeding pairs in the UK and it is hoped that the new nesting platform will give people in North Devon the chance to observe them during their trips between the North of the UK and West Africa.
