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.

Tawny owl    Kodukakk      Strix aluco

 

At the evening flight outside, at seven o’clock, there was a third egg in the nest hollow. Very  rarely five eggs are found in a tawny owl clutch (literature indicates a possibility of up to eight eggs), more often there are three eggs here: round, white ones, the size of a ping-pong ball.

Buzzard; Common buzzard    Hiireviu         Buteo buteo

 

Yesterday snow fell briefly in daytime in almost all of Estonia except in the islands.

Buzzard pair Mari and Mihkel, familiar to us from last year, showed themselves briefly for the first time at the nest on Sunday afternoon. In the video we see that yesterday they were already busy with ”nest decorating”.

The buzzard camera will open in the next few days.

We were a little too quick with yesterday’s incubation story – in early morning light the view opened on female Anna’s third egg, probably laid late yesterday evening. Now the clutch should be complete.

So the first egg for Women’s Day, the second on March 11th and the last one on March 14th. Incubation is in process and we might begin to expect the hatching of eaglets from April 11th onwards.
