Introducing strix varia or the barred owl, also known less formally as the Hoot Owl. Barred owls are native to the North East of America, but have extended their range across to the west coast, where they are seen as invasive and a threat to the more local Spotted Owl.
Barred owls are greyish brown in colour and sometimes thought of as a little drab. They have a striped underside, large heads and no ear tufts.
The barred owl has a lengthy call, transcribed as ok-ok-ok-ok-ok-buhooh and translated for human minds to who cooks for you, who cooks for you all. The second link below gives some lovely examples of owl songs and their mnemonics…
