Great Tit Year science news edited by Marko Mägi, bird ecologist at University of Tartu
The first clutches of great tit chicks have left the nests. However, few of them will reach a reproductive age, because during the week after leaving the nest a great part will fall victims to predators. Having reached adult age the chances of living on further are relatively great and so it is extremely important precisely in the first weeks of life to make the right decisions outside the nesr and keep alive.
The first decision that the fledged chicks have to make is the time of leaving the nest – to leave in early morning, at mid-day or even at dusk? Is there a ”best time” for leaving the nest?
