The birds sounds are very real with good sound quality. Some of them are longer, some are shorter. I replaced my old Audobon, the one with the owl at 12, and the difference is big. Way better quality, also in its parts.. real wood frame vs plastic, a very gentle tick and very nice colours of the birds printed on the display. Although there are only European birds, so I don't know most of them. KOO KOO should make a version with northamerican ones! they'll sell tons!!
very happy with my new clock overall, specially now that I'm home more than ever.
