Last night western Saaremaa in Estonia turned wintery with the degrees of cold.

The vernal equinox has arrived and, as often before at this time, weather arranges little pranks, sometimes looking like winter, sometimes spring. But we can enjoy the longer daylight time more by each day and it brings a smile to all around us.

In western Saaremaa winter turned the spring-like view  into snow white – the last time that snow covered the islands was in January. Snowflakes (Leucojum) flowered and go on flowering. In Hiiumaa flowering Hepaticas have already been noted. Geese migrate, cranes call and it is audible even in the web cameras.

Klaara’s fourth egg

On Thursday Klaara somehow did not at all want to fly out in the evening from the nest hollow. Klaus came calling on her but it seemed more sensible to him to bring Klaara a mouse… In early morning the fourth egg was in the nest.

In stormy weather there may be interruptions in the webcam operation, but our viewers know that breaks occur in direct stream transmission from forest life from dozens of reasons.

Klaara already knows that Klaus will bring something edible to the nest (we cannot hear those sounds).

In the beginning of the video the calls of Klaara and the more masculine “approval” from male Klaus - when his beak is free from the food – can be clearly seen and heard. If the web camera is open in the background we can often have an idea in advance of the doings of the tawny owls.

First evidence of ”bird talk” comes from tits

We know that human speech consists of various vocal elements (sounds or notes)  that combine together to form words which in turn form sentences. Animals interact similarly: for instance among birds and mammals specific predator warning calls have developed. However, it was not known until now whether animals use combinations of calls to transfer a message with complex content.
