During my 2025 winter trip to Andøya, Norway, the temperatures were unusually high, leaving most of the ground free of snow for extended period of times. Spotting this fully white ermine did not prove challenging! Keeping track of it as it bounced up and down the landscape was quite tricky however, and I am glad I managed to capture the 0.5 seconds it spent on top of this rock before darting to its next viewpoint.
