Early on Sunday morning the nest box of the great tits was empty and desolate. The female spent the night in the nest box and the male guarded the surroundings to keep off intruders or even other nest contenders.

By Saturday  morning the great tit had laid an egg


Great tit     Rasvatihane      Parus major


Great tits nest everywhere in Estonia and this year about 300-400 thousand great tit pairs will build a nest.  In camera view birds have spent the night in all nests but the egg is in the first nest box. There is quite a lot to tell about our ordinary great tits during the breeding season.

Latvian badger castles

This year, the Badger Year, Latvian zoologists installed several track cameras in protected Latvian forests. As in Estonia, our southern neighbours until now have no proper overview of their badger population. To complement the knowledge about badgers the Latvian forest agency Silava chose three large badger castles in northwestern Latvia in a nature reserve area, installed the cameras and now have sent us pictures and video cuts. In the video we can see how the badger –   āpsis in Latvian  – scratches itself. The other members of the large castle are not visible at the moment but it is known that a large number of inhabitants live there, more than in the home of our video stars in Saaremaa.

Birds see faster than believed earlier

Blue tit

Hawk-eyed, eagle eyed –the expressions are tied to the keen eyesight of birds.

Birds whose eyesight is noticeably better than that of humans are also able to see light invisible to the human eye – radiation in the UV part of the spectrum. The visual capacity of birds does however not stop there. Since many birds catch their prey in the air, they must distinguish a great number of details in movements in order to be successful. While a human viewer sees what happens on a film screen as a uniform smooth movement when in fact looking at images that change at a rate of 24 frames per second, then birds are able to see many more frames per second individually.
