Stanley Park Owls - Species

Stanley Park Owls - Species

I have seen (and photographed) four species of owl in or around Stanley Park - Barred, Great-Horned, Saw-Whet and Snowy. The latter was seen at Sunset Beach (a nearby park) during an "irruption" year.

Another five species are possible visitors - as determined from sightings or other reports. These include - Great Grey (seen for two weeks one winter), Western Screech and Pygmy (heard during call-out surveys), Barn and Long-Eared (semi-reliable reports). Sadly, the Western Screech has not been seen for many years, replaced by the Barred.

The Short-eared Owl  has not been reported in Stanley Park. It is found elsewhere in the Lower Mainland.

The Hawk Owl and Burrowing Owl have not been reported in Stanley Park. They are very rare visitors to the Lower Mainland.

One species you will not see is the Spotted Owl, but I have included information on it for completeness. It is close to extirpation in Canada.

 

 

Barred Owl Strix varia Weight: 800 g. (female). 630 g. (male) Length: 51 cm. (female). 48 cm (male) Wingspan: 107 - 111 cm. Longevity: maximum 18 years in the wild. Status in Stanley Park: Our most common owl - there are three confirmed breeding pairs and probably a few more "floaters". Barred Owls are also seen in the surrounding urban areas.

The Barred Owl has been blamed for the decline of the Spotted Owl. However that is only part of the story - human modification of the landscape has favoured the more adaptable Barred Owl.

Centuries ago the Barn Owl learnt to adapt to our agrarian modifications of the landscape and found ideal nesting conditions in our ancestor's barns. Now the Barred Owl may be doing something similar in adapting to our cities - using parks for nesting locations and finding good hunting in the squirrels, rodents and other creatures that we bring with us.

Great Horned Owl Bubo virginianus Weight: 1000 - 2500 g. (female). 680 - 1450 g. (male) Length: 60 cm. (female). 51 cm. (male) Wingspan: 143 cm. (female). 134 cm. (male) Longevity: longest recorded in the wild is 28 years, 50 in captivity. Status in Stanley Park: Probably a year-round resident, but sightings are rare. It may just be post-breeding dispersal.

I have had about a dozen encounters with Great Horned Owls in the park over my time in Vancouver.

Great Grey Owl Strix nebulosa Weight: 925 - 1700 g. (female). 800 - 1175 g. (male) Length: 59 - 69 cm. Wingspan: 130 cm. Longevity: maximum 16 years in the wild. Status in Stanley Park: A rare visitor - in irruption years. The photo at left is of a captive bird, undergoing rehabilitation at O.W.L.

During an irruption, many years ago now, one was present in the park over the Christmas - New Year period. I just happened to be away and missed it completely!

Long-Eared Owl Asio otus Weight: 260 - 435 g. (female). 220 - 305 g. (male) Length: 37 - 40 cm. (female). 35 - 38 cm. (male) Wingspan: 110 cm. Longevity: longest known in North America is 9 years in the wild. Elsewhere the record is 27 years. Status in Stanley Park: A rare visitor - post breeding dispersal? This photograph was taken at Reifel Bird Sanctuary.

I know of only one possible sighting of this species in Stanley park and that was from 2005 (?) when I just missed an encounter. Soon after leaving a naturalist/photographer near Prospect Point when he encountered a probable Long-Eared Owl.

Short-Eared Owl Asio flammeus Weight: 280 - 500 g. (female). 200 - 450 g. (male) Length: 38 cm. (female). 37 cm. (male) Wingspan: 95 -105 cm. Longevity: maximum recorded in North America is 4 years in the wild. Elsewhere the record is 20 years. Status in Stanley Park: No known reports.

This photo was taken at Boundary Bay, Delta.

Barn  Owl Tyto alba Weight: 400 - 700 g. Length: 29 - 44 cm. Wingspan: 110 cm. Longevity:  I have seen good authorities quote 8 and 17 years maximum in the wild. However, most adults live only a few years. At the extreme of their northern range here. Extreme winters (AKA normal Canadian winters outside the Lower Mainland) claim many. Over 30 years in capativity. Status in Stanley Park: Uncertain - unlikely to be resident. The only suitable habitat is the area around Brocton Point, but this is pure speculation on my part. I know of only one possible sighting, from the 1990's -  near the causeway overpass.

This photo was taken near Boundary Bay in Delta (2016).

The Barn Owl is at the northern limit of its range in our area. It is able to survive at such latitudes because of its habit of nesting in barns and other enclosed spaces. These provide warmer locations for roosting and rearing their young. This ability to adapt to human agriculture has made it one of the most widespread birds in the world. However, changes in our agricultural practices have lead to declines in many areas, but now many localities are putting up dedicated "mini-barn" nest boxes to encourage their return.

Snowy Owl Bubo scandiacus (Nyctea scandiaca) Weight: 780 - 2950 g. (female). 700 - 2500 g. (male) Length: 60 - 70 cm (female). 55 - 64 cm. (male) Wingspan: 132  cm. Longevity: maximum 10-11 years in the wild, 28-35 in captivity. Status in Stanley Park: Possibly a rare visitor - in irruption years - more likely to be seen in the Boundary Bay area. I observed one in February-March of 2001 on Sunset Beach (near Stanley Park).

The photo above was taken in 2001 on Sunset Beach.

Northern Saw-Whet Owl Aegolius acadicus Weight: 100 g. (female).  75 g. (male) Length: 20 - 21.5 cm. (female).  18 - 20 cm. (male) Wingspan: 43 cm. Longevity: maximum 10 years in the wild. Status in Stanley Park: Probably a year-round resident, but because it is small and almost exclusively nocturnal it is hard to find. I have seen 3 in 10 years and two of those were during release of rehabilitated birds!

The photo above was taken in 2006 - October 17th. My friend Jerry located it roosting in late afternoon on the edge of the wetland. This photo was taken just after sunset when it became active.

My second "sighting" was for the release of a rehabilitated bird in 2008 - December 3rd.

My third and final (Stanley Park) sighting was also of a rehabilitated bird released near the first location and also alerted to by Jerry, in 2009 - March 21st.

I do know of other daylight sightings where people have come across an owl on the ground or roosting - including amy own experience with one at the Inukshuk. The species is not timid - it does not take immediate flight once located - so if you are lucky enough to find one just stay quietly and enjoy! Oh, and don't forget to tell me about it :)

Northern Pygmy Owl Glaucidium gnoma Weight: 73 g. (female). 62 g. (male) Length: 16 - 18 cm. Wingspan: 30 cm. Longevity: unknown. Status in Stanley Park: Uncertain - during migration? During the call-out survey of March 2009 one member of the team heard a Pygmy Owl call.

This photo was taken on Cypress Mountain, West Vancouver, in 2014.

Also seen some winters at Maplewood Flats, North Vancouver.

Northern Hawk Owl Surnia ulula Weight: 320 - 345 g. (female). 270 - 314 g. (male) Length: 36 - 39 cm. Wingspan: 74 - 81 cm. Longevity: maximum 10 years in the wild, North America. Elsewhere maximum recorded is 16 years. Status in Stanley Park: No known reports.

This photograph was taken on Westham Island, Delta, December 2010.

The winter of 2010-11 was the only time I experienced such a visitor to the Lower Mainland. There was another in 2017-2018 but I didn't get to see it - no transportation and too many people!

Western Screech-Owl Megascops kennicottii Weight: 157 - 250 g. (female). 131 - 210 g. (male) Length: 21 - 24 cm. Wingspan: 51 cm. Longevity: maximum recorded is 13 years in the wild, up to 19 in captivity. Average is just a few years. Status in Stanley Park: 30 or 40 years ago this would have been the resident owl for the park, but now we have only rare reports of this species.

The photo above is of a captive bird, undergoing rehabilitation at O.W.L.

During the call-out survey in March 2008 there was a response from a Screech-owl in the area south of Beaver Lake. Later in the year there was a possible sighting north of Beaver Lake.

In September 1999, when I was far less familiar with the different Owl species, I recorded seeing an eared owl, with yellow eyes in the same area. I referenced the size in relation to the small bird box on which it was perched - approximately the same height. For some reason I assumed it to be Great Horned Owl - possibly because that species was known to frequent the park at that time. Later re-examination of the bird box revealed it to be 21 cm high - a much closer match to the Western Screech-owl!

Spotted Owl Strix occidentalis Weight: 550 - 760 g. (female). 520 - 700 g. (male) Length: 41 - 48 cm. Wingspan: 100 cm. Longevity: maximum 17 years in the wild. Status in Stanley Park: No recorded observations.

This is the species that "should" be present in our area. Unfortunately human devastation of the coastal old-growth forests has driven it to extirpation. It is similar in size and hunting methods to the Barred Owl, but requires undisturbed habitat. We (humans) are simply replacing Spotted Owl habitat with that more suited to the Barred Owl.

In the 1990's the Spotted Owl made headlines in the western United States when it became listed under their Endangered Species Act. That required extensive protection of habitat. Various negotiations with the logging industry have since lessened the protection, but at least some protection has been afforded. In Canada we have no effective legislation for protecting such habitat. Some protection of breeding areas is in effect, but those areas are so isolated as to be ineffective in providing sufficient contact between the surviving individuals.

In the spring of 2009 I happened to meet a naturalist who had been involved in surveying the Canadian sites a decade earlier. At that time there were estimated to be only 22 pairs. By 2009 he estimated only 17 individuals remained.

There are also some issues with the surveying methods. These rely largely upon call-outs - playing the sound of owl calls and waiting for a response from a resident owl. Great care has to be taken in using this technique - one species my not respond to its own species call if another (threat) species is present. In this case the Spotted Owl may not respond if there are Barred Owls in the vicinity. Under normal circumstances this may not be an issue, but with so few Spotted Owls it could result in their territory not obtaining what limited protection Canadian regulations may provide.

There is also a general feeling that Canadian officials have "given up" on the Spotted Owl and are just waiting for confirmation of its extirpation from our country.

Burrowing Owl Athene cunicularia Weight: 120 - 250 g. (female). 130 - 185 g. (male) Length: 19 - 25 cm. Wingspan: 53 cm. Longevity: maximum recorded 11 years in the wild. One banded bird at 8 years (differing authorities). Status in Stanley Park: No known reports.

A single bird was sighted in 2017 not far from Iona, but was harassed by the birding paparazzi and had to be relocated by Wildlife Officers. I believe this species was resident in the Lower Mainland until the early '70s.
