Birds confused by chirping apps

Mobile phone applications, or apps, are practical tools for many. But for others it could turn the world up-side down.

An ornithologist tells Swedish Radio P4 that app versions of ornithology books, with recorded sounds of various birds, can cause havoc in nature and should be used sensibly.

"Male birds experience the sounds from the apps as giant versions of their own species. Either they give up and leave their territory, or spend all their time defending their turf instead of feeding their young ones," says ornithologist Kent-Ove Hass.

Some species, such as woodpeckers and owls, respond more readily to the app twittering than others.
