Great tit loses one-tenth of its body mass during long winter night
Text University of Tartu bird ecology researcher Marko Mägi and coordinator of the Year of Great Tit Margus Ots,
The great tit that has been staying overnight in the nest box has gathered many viewers via the webcam. Lately it has arrived in the nest box in the evenings between 16.00-17.00 and left by 8.00 at the latest in the mornings. Thus it sleeps more than 15 out of 24 hours during the dark period. How much energy does the tit use during the long winter nights and how much weight does it lose?
