During the first great and lasting thaw in February black grouse mating displays, or leks, certainly could be seen. See earlier article : LINK

Söödaplatsil käib umbes veerandsada hirvepulli, igal loomal peas kordumatu kujuga sarved. Vähestest viisidest, kuidas hirvekarja liikmetel üldse vahet teha, ongi nende sarved. Üks pull on pool sarve ära murdnud, teisel üks sarvepulk kolm korda lühem kui teine, kolmandal paistavad veel väheldased sarved aga ideaalilähedaselt sümmeetrilised…

When we celebrate Estonia’s 98th anniversary  the eagles are prepared to do so too.
 
Two days before the Anniversary of the Estonian Republic the female arrived in the white-tailed eagle nest where the webcam is installed. The male who until then had guarded the nest alone at once became active, started to arrange nest material, brought more branches, talked with his mate.

Glaze frost on birch branches
 
A winter rainfall that freezes on the ground is called glaze ice, but when it does so on trees, power lines or or on objects above ground in general then glaze frost.
 
Yesterday ice rain fell from nimbostratus clouds, dark, low-level clouds, at a height of about one kilometre and this weather phenomenon we can still feel in the next few days.
 
The precipitation of ice rain is caused by a warm air layer when the
