Only recently the ability of great tits to memorise the location of food hoards of other birds by observing their behaviour was mentioned among the Bird of the Year science news (see note  here). It is known that great tits are better at solving tasks requiring spatial memory than blue tits or marsh tits.

Squirrel in snowfall at the end of January

I live in Tallinn, in a block of flats in Mustamäe. To my great joy squirrels have started to visit us. Sometimes there are even several of them. We have put some nuts or acorns on the windowsill. It is interesting to observe them from the other side of the window.  They don’t notice me and I get the opportunity to photograph them at a very close distance.

In the Winter Garden Bird Watch that took place for the 8th time on the weekend of January 21 – January 22 more than 43 000 birds of at least 60 species were noted. On Monday morning 1900 bird enthusiasts had reported their observations. They had observed garden birds in 1300 places in Estonia.

Results can be sent in until February 6th.

The most numerous species was once again the great tit which made up a third of the total number of observed birds. As in previous years house and tree sparrow and greenfinch and hooded crow were also among the top five.

You may very well know who is guilty of mischief, but you still have to repair it yourself.

During the whole autumny winter period one storm has chased another. Water and air hold a couple of plus degrees. Soon the whelping period of gray seals begins. We will see if the camera angle can be adjusted until then?
