That is extremely far north. Are you sure about the locality ?

Theo, it is far north, but also far west. Winter temperature in Nizhny Novgorod (where it was recorded) is colder than in Petersburg.

Are your cities too clean to support a pigeon population?
I recall reading your House Sparrows were in decline. In America they remain abundant urban pests.

John, our cities are still full of pigeons. It is not because of lack of sanitary, but because a lot of people, mostly old ones which specially feed them.
As for sparrows you are partly right, P. domesticus became less common in Moscow, it is partly replaced by P. montanus which was uncommon 40 years ago when I was schoolboy. In the northern cities like Murmansk there is only P. domesticus, in small towns around Moscow still more P. domesticus than P. montanus. I suppose that it is a result of heating. If you visit Madagascar or Thailand, you find only P. montanus.

Josef, Nikita, Siegers, John - thank you!
Nikita, sorry, but the fly flew away just in the process of photographing. I will collect the next specimen of this species for your museum - although perhaps not immediately. I must say, I rarely see this species.
