Years ago, when I was camping alone in a big forest in Sweden to photograph black grouses, some deep whooo’s woke me up in the middle of the night. I had never seen great grey owls in the wild before, but knowing there was one not far from my tent made me shiver. These are the moments in nature you never forget. I happily fell back asleep and tried to find the owl in the morning, but without any success. It would take me until last week to finally see this bird, when I travelled to northern Finland.
