On only second night of running the Boreal Owl caller we caught one! This was my first ever seen or banded, so it was great bird for me, especially catching it at 4am after a fairly slow night of Saw-whets.
Kind of a bigger, evil brother of the Saw-whet
Chunky bird with big furry legs, taking the same band size as a Long-eared Owl, though only weighing about half as much.
