Looking at an incubating great tit in the webcam the question might come up – how can it incubate the eggs through the fluffy plumage? Feathers have a very poor heat transmission capacity after all. To make the body heat reach to the eggs the feathers of the female great tit on the abdomen drop off, and a skin area without plumage is created – the brood patch.  So during the brooding period the eggs come into contact with the skin of the abdomen  that is rich in blood vessels and the heat  needed for the development of the chicks reaches the eggs.

Maple flowering

Maple; Norway maple    Harilik vaher        Acer platanoides

The flowering start of maples marks the beginning of proper phenological spring.

A maple in full flower – it is a real sight. On warm and sunny spring days we hear the buzz of bees and other insects from the trees who, oblivious of themselves, gather nectar as well as the greenish pollen necessary for the activities of the organism.

Butterbur

Butterbur      Harilik katkujuur      Petasites hybridus

The comparatively little spread butterbur is an alien in Estonian nature that has arrived from abroad. In medieval times the propagation of the plant was aided by the monasteries because from the leaves and rhizomes of the plant a remedy against plague was prepared which is also reflected in its Estonian name ”katkujuur”, plague root.
