It occupies its territories as soon as there are snow-free areas. The males begin to sing in the morning in complete darkness, mostly before other thrush species. Snowfall in spring may occasionally drive the birds back to lower altitudes where they hold out for a few days. It is remarkable that large numbers of northern passage migrants cross our country practically unnoticed on the way to their wintering places in Northwest Africa. In this case, our awareness of visible bird migration does not fully correspond with reality.
