Ecologically species can be divided into specialists and generalists. While the specialissed species are adapted to specific environmental conditions and rapid changes may become difficult for them, then generalists can cope with a variety of conditions – both urban and rural, warm or cold, in forests or open spaces. Thus it is no surprise that that the generalists are often synanthropes, or associated with humans, i e species that have been able to adapt urban life and become numerous, due to their high adaptivity and small selectivity. One of the best known generalists is man himself who can cope in all regions (except the Arctic areas). Few animal species manage to match humans in this.

One of the characteristics in Estonia’s new visual identity is the concept of erratic boulders. Estonia has the greatest number of erratic boulders in the whole of Europe.

This might inspire nature fans to go on a trip to see some of the more sizeable giant boulders for themselves for a change. Bare trees and an almost non-existent snow cover favour such ventures in all ways. Even in a dense thicket all kinds of geological sights stand out much more clearly now. 

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?
