Now birds brag by mimicking mobiles

The irritation is about to get worse. Already inescapable on the train, at the restaurant and in the office, the sound of a mobile phone ringing is about to destroy the peace hitherto offered by a country walk.

The irritation is about to get worse. Already inescapable on the train, at the restaurant and in the office, the sound of a mobile phone ringing is about to destroy the peace hitherto offered by a country walk.

Male British birds have taken to mimicking the noise made by mobile phone ringtones. And not unlike the first human mobile users, their noise is all to do with bragging about their success and attracting the opposite sex.

The phenomenon has been noticed mainly among starlings ­ distant relatives of the mynah bird ­ and song thrushes, although the blackbird and the marsh warbler are not immune.

Mike Everett, a spokesman for the Royal Society for the Protection of Birds, said birds had long imitated man-made sounds, from the human whistle to car brakes screeching.

“Birds have always imitated mechanical and electronic sounds. Not all of them do it but some are great mimics. About 10 per cent of a starling’s song is mimicry.

“The better they are at a varied song and puffing their chest out, the better they will be at holding their territory and finding a mate. It is a macho thing really,” he said.

Mr Everett said the development could help bird populations if it encouraged more breeding. It would be particularly beneficial for starlings whose population has fallen by about 50 per cent.

There is some relief: the more intricate ringtones are unlikely to be copied by birds, as their range is restricted to more simple tunes.

Knowles EK3029c

This is the microphone element recommended by Old Bird for recording night migrating thrushes, sparrows, and warblers. It is excellent for recording flight calls whose frequency is above 2 kHz, and note that the C1 capacitor is built in. The frequency response of the element can be seen on the Knowles Electronics EK series webpage. The element has a 12 dB per octave rolloff below 2 kHZ, thus greatly reducing rumble from wind, road, or aviation noise. High frequency sensitivity begins to drop off above 6 kHz but this is largely compensated for by the 6 dB gain in sensitivity from the dinner plate reflector.
