Snowy Owl, globally Vulnerable


The Snowy Owl has recently been listed as globally VULNERABLE. See: http://datazone.birdlife.org/species/factsheet/snowy-owl-bubo-scandiacus or http://www.iucnredlist.org/details/22689055/0. Population size and the extent of the declines are both poorly understood; however, despite the uncertainty, there is sufficient evidence for a listing of Vulnerable. We don’t really know why the numbers are declining but reduced food supply (perhaps due to climate change) and the high rate of collisions with vehicles and infrastructure have been suggested.
