COSEWIC assessment and status report on the Northern Saw-whet Owl brooksi subspecies, Aegolius acadicus brooksi, in Canada .: CW69-14/490-2018E-PDF
"This distinct subspecies endemic to Canada has a small population of fewer than 2000 breeding individuals, restricted to the islands of Haida Gwaii off the Pacific coast of British Columbia. It is a forest specialist, preferring older coniferous forests with abundant nesting snags and an open understory. Numbers of breeding birds are anticipated to further decline over the next 15 years as a consequence of ongoing forest harvesting. Other continuing low-level threats to this subspecies include problematic invasive, introduced and native species, accidental mortality from road collisions and effects of forest fires. As just over 70% of Haida Gwaii is now within protected areas reserved from forestry operations, including National Park Reserve, provincial park, and reserves under the Haida Gwaii Strategic Land Use Agreement, this subspecies is not at risk of imminent extinction"--Assessment Summary – November 2017, p. iii.
