After reading Pauls and Ilians posting on their vipers in the U.K., I had to look around here also
The last 3 or 4 days it got warmer (at least during the day hours) and the ground isnt frozen since 2 days now.
We had a very cold 2011 till now with only a little bit of snow. Therefore the cold could get deep into the ground.
But today the adders have been out (but not last weekend).
I found 3 males within two hours in the "IBM" peat bog.
Ibm is the real old name of the village - has nothing to do with IT.
Close nearby is the village "Fucking", where the the road signs get stolen more times a year
I had a look also to some ponds and ditches, but all are covered with a quite thick ice layer.
I´ve never seen a black male there
