The dark art of finding who's hooting the night away in Manitoba forests

Christian Artusopacks along-lens camera andbinoculars into the car just in case, but it's his headlamp and ears that will really come inhandy when trying to locate elusive owls in the dark in eastern Manitoba.

"We probably won't see very much," Artuso says. "I really enjoy hearing them against the quiet of the forest."

He turns north off the Trans-Canada Highway and drives down a bumpy gravel road that cutsthrough boreal forests.

Artusostraps that headlamp on and stepsout of the car parked next to a frozenbog. As thesun sets and temperatures drop below freezing, he sights a familiar silhouette perched on a dead tree in the distance. It's a great grey owl that takes flight andhovers over the bog, looking for dinner.

"When you get a chance to observe them hunting absolutely fascinating to watch," Artuso grins as the owl disappears hungry, its scurrying prey hiding deep in the cattails and snow.

Before long it's totally dark, and apart from the stars sparkling overhead, the only light in the area is a glowing orb that seems to float in midair but isactually hanging fromArtuso'stuquedforehead.

He pulls out a pencil and stopwatch, clicks "start" and begins the first of several counts for the night, where he listens silently for faintcoos, hoots or other signsowls are nearby.

"Owls are super special they have a charisma," Artuso says with a slight shiver to his voice as the mercury dips to5 C.

"Some people say the fact that their faces are like ours two eyes pointing forward, the human-like face is part of the appeal.I'm not really quite sure what it is."

Under his supervision, dozens of volunteers return to rural sites like this near Richer, Man. about 55 kilometres southeast of Winnipegeach spring to check on owls for the Manitoba Nocturnal Owl survey.

Observations of owls, mostly heard and not seen, are recorded and pooled into a Nature North database that tracks the frequency and number of the predatory birds in Manitoba.

The surveys usually taper off in early to mid-April, but because of the unusually cold spring Artuso says he planned to extend the surveys later into the month.

30 years on

The survey started nearly 30 years ago and has taught us a lot about Manitoba's 12 owl species that we didn't previously know.It filled a gap left by other massive citizen science-driven surveying projects that take place during the day and generally didn't catch whatnocturnal species were up to.

Thanks to the efforts of nearly 1,000 volunteers since the program's inception, we nowknow that Manitoba owls are generally faring well, save for the short-eared owl and burrowing owl.

Thosespecies areat risk of disappearing in Manitoba due to habitat loss to farming, infrastructure and the encroachment of human activity.

But one of the things that lures Artuso and volunteers out into the cold nights every spring is the prospect of maybe seeing or hearing one of the 10 more common species. That includes the palm-sizedsaw-whet owl that "sounds like a truck backing up in the bush," and the barred owl, whose song sounds like"who-cooks-for-you."

Manitoba Nocturnal Owl Survey co-ordinator Christian Artuso imitates a series of commonly found owls in the province.

Three of the 12 speciesaccounted for 75 per cent of alldetectionsin the first 25 years of the surveysaw-whet owls were most common, followed by the great horned owl and boreal owls. Great greys, barred and the long-eared owl are the fourth, fifth and sixth most commonly detected.

Passing the torch

Artuso took over the reins of the survey from Jamesand Patsy Duncan after the 2015 owling season.

"It is time for younger, smarter and more tech-savvy people to take over and to improve the survey," James Duncan, the director of wildlife and fisheries for Manitoba Sustainable Development,wrote in the nocturnal owl survey report that year.

The long-married couple launched the survey in 1991 to encourage people to develop more of a relationship with owls and conservation, and to help researchers cover more ground.

The unique program that started in Manitoba has been so successful that it has spawned a wave of similar owl projects in other provinces.

"When you think about the cumulative investmentpeople donating their time, driving in the middle of the night all over hell's half acrethat's a substantial contribution on their part," James Duncan said.

He and his wife are more than just interested in owls. They live with amongthem or maybe it's the other way around.

For several years,Nemo the long-eared owllived with the Duncans in their home and in an enclosure in the backyard.

Nemo became a wildlife ambassador that Jamesshowed off to classrooms of kids to helpexplainhoweonsof evolution have equipped owls with stunning ears, eyes that see in the dark, heads that swivel and long wings that allow them to silently swoop down on rodents.

Nemodied in 2015 but was given an award for all the time he spent swooping around (and educating) kids. The Duncans now have a one-year-old great grey owl named Oskaand a three-year-old owl named Rusty living in their home, and in enclosures in their yard that have taken over Nemo'sprevious role as ambassadors.

Though he's no longer the co-ordinator, Jamesand his wife remain contributors to the survey.

"I went out last night," he said, adding they heard a lonely great horned owl, some sandhill cranes and cold-sounding wood frogs chirping the night away.

"Part of the appeal of the survey is all the other things you experience.[We heard] a pack of coyotes that, gee, it felt like they were howling just a stone's throw away from the road. I'm sure they were farther but at night everything seems to be amplified."

'Lovable' harbingers of death

Back out in the dark,Christian Artusohears a saw-whet and barred owl calling at each other on the final point of the night.

"It almost seemed as if they were each angry at each other," Artuso says.

Those were the only two owls heard during the night, but itstill counts as a win.

"Those zeros are important," he said. "I would call that a successful night out. Some beautiful stars and a lot of fun."

Though some people and cultures fear owls, Artuso has always been drawn to the predatory birds, and that doesn't sound like it's going to change anytime soon.

"In many cultures, owls are seen as either messengers of death or [are] associated with spirits. Actually, around the globe that seems to be quite prevalent. I've encountered that in Africa and Asia. It's also true here in some North American Indigenous cultures, which I find quite interesting," Artuso says.

"I think that has to do with some of the human-like nature of owls and the fact that they're nocturnal. Like many things, once you learn a little bit more about what they are, they're actually fascinating and beautiful and quite lovable."
