Birdsong phone apps 'harmful' to birds, say Dorset experts

Word I didn't know:
harmonic: harmonica
pleasant: agradable
divert: desviar
duties: funcions

Summary:

The sounds of the mobile phones are a selection and specific sounds for people. The experts must try the best harmonic sounds for human. The bird sounds is a real pleasant for the heart of people. For this reason all the mobiles phones have birdsongs, but these sounds are a problem for the species  because when the species, basically birds, listen these sounds,  they can divert their important duties.

Opinion:

Maybe, it’s true that these sounds change the birds direction or facts, but for the human’s ear is a good and relax sound for entrainment  because the two species can be good the humans control this bird sounds when we’re going to listen it and we look in where place we can listen for protect this birds and the all species.
