Ina, do you have pictures from your now over 1 year old wolves, so that we can see that there is no black mask any more? The pics you gave us the link show only young wolves under one year. If I understand it right you say that wolves have till one year black mask.
Is it with every grey wolf so? I thought I saw young wolves with white mask.... For me it is completely new that europaen grey wolves have black mask in the first year.
