VANCOUVER — Along her journey towards understanding Vancouver's crows, psychology professor Suzanne MacDonald says she made a friend.
It's a crow that brings her gifts after she set up a bird feeder at her home in the neighbourhood of Kitsilano.
Once, it was a barnacle-covered shell, which MacDonald treasures. Other times, it was 'bits of garbage' that MacDonald doesn't fancy much, though she 'appreciates the sentiment.'
'I think he definitely recognizes me. When other people go out on my patio, he doesn't come to them. He knows me,' said MacDonald.
Vancouver has long had a love-hate relationship with its crows, whose dive-bombing attacks on pedestrians are a sure sign of springtime in the city.
But a new survey co-authored by MacDonald suggests that, on the human side at least, it's mostly love.
'I think that many people feel a deep connection to crows because they seem to see the world the way humans do: they are intelligent, excellent problem solvers, they recognize individual humans, and they are highly social, culturally complex beings,' said MacDonald, a psychology professor at York University, who divides her time between Toronto and Vancouver.
MacDonald and Laura Adams, who teaches psychology at Langara College, teamed up to survey hundreds of people in B.C.'s Lower Mainland to examine their relationship with crows.
They said 67 per cent of people had positive feelings about crows, compared to only five per cent with negative feelings, in findings released this month that the researchers hope will inform an academic publication later.
As for the crows, many make their feelings known during the spring nesting season, when the Wildlife Rescue Association of B.C. says 'overprotective' parent birds swoop on anyone who gets too close to a nest.
It's a common experience across Vancouver — an online crowdsourced map of crow attacks in Vancouver is dotted with red crow symbols marking swooping sites gathered over several years.
But Adams said most people felt 'very positive' about crows, even if they had been dive-bombed.
'We were really hoping to compare the types of people who loved crows and the types of people who had very negative opinions on crows because talking to the general public, people seem to be in both camps,' said Adams.
But it turns out most respondents were crow fans.
'We found that 64 per cent of people said that they'd been dive-bombed by a crow. So, when you put that in the context of 67 per cent of people feeling very positive about crows, that means there are a lot of people who've been dive-bombed but still love crows,' said Adams, 'We found that really interesting.'
Many of the 468 survey respondents shared stories about their unique relationships with the birds.
'I think one of the interesting parts is just how much people wanted to talk about crows for no reward at all,' said Adams.
Vancouver has even had its own celebrity crow, named Canuck, that was well known for riding the SkyTrain, stealing a knife from a crime scene in 2016, and forging an unlikely friendship with a mail carrier.
Adams said the survey found 53 per cent of people felt crows were a symbol of Vancouver.
Wildlife photographer Liron Gertsman has been fascinated with crows since he was five, and that obsession turned into a documentary, filmed with friend Jack Bailey.
Their 10-minute production, 'The Commute,' captures the story of a massive murder of crows — up to 10,000 birds strong — that congregates at Still Creek in Burnaby at night. The huge flock is a familiar sight in Metro Vancouver skies, particularly in winter months.
Gertsman called it an 'incredible phenomenon.'
'They're just so smart,' he said, as he described the challenge of locating the birds, only to turn up for more filming and 'they'd be nowhere to be seen.'
'So, they were playing games with us a little bit. They were taking us on a not a wild-goose chase, but a wild-crow chase around the city,' he said.
Gertsman said that during filming he and Bailey were pooped on 'all the time,' but it didn't dampen their enthusiasm for their subjects and their 'beautiful daily commute.'
He's still watching crows during the current nesting season. 'There's a crow nest that is just barely visible outside my window, tucked into the tree, which is fun to watch,' Gertsman said.
'I think it's a lovely thing to be able to look outside your window in the morning and see a crow because it represents that little bit of nature that is able to exist within even a pretty big city.'
The Wildlife Rescue Association said nesting season lasts from April to July, meaning 'anxious bird parents are out in full force' to protect their young.
The association said it's seeing a spike in reports of fledgling crows on the ground, and there are 11 injured and orphaned crows in Wildlife Rescue's care.
The organization's co-executive director, Linda Bakker, said it's common to find young crows on the ground in late spring as they learn to fly. Not all need help, but if a grounded bird looks like it's in trouble, people should can take a photo and contact Wildlife Rescue, she said.
She said the group often gets calls from people asking how to deal with crow attacks. But she said that when it happened to her, she wasn't worried.
'I was excited when it happened. I was like, oh, there's a crow, and he's protecting his nest. That's great. I will stay out of your way,' said Bakker.
MacDonald said it's important for people to understand how we live with other species, particularly in an urban environment where many animals have been pushed out.
'But some of them, like crows, actually thrive with us, and that makes them very special,' she said.
MacDonald says daily encounters with crows should be seen as a reminder that 'if we live in a city that has no wildlife, then we live in a dead city.'
'We want to live in a very vibrant city where nature is at our front door and our back door and everywhere, and crows remind us that is the case in the Lower Mainland.'

Workshop being held in Windsor to assist people with the legal name and gender marker change process in Ontario

A workshop is being held in Windsor on Saturday for the 2SLGBTQIA+ community. Dana Rosamund Teagle is leading the workshop. Rosamund Teagle is a web and software developer for , a free online tool that helps navigate the legal name and gender marker change process in Ontario. The site offers guidance on required documents, fees and steps — with a focus on trans inclusion and reducing administrative barriers. Rosamund Teagle said they've been running ID clinics for teaching trans people how to change their name and gender markers in the province since 2021. 'If I can be a person who's like, hey not only have I been through this myself, I've also helped this huge pile of people go through it as well, and I think that gives people short of the confidence they need to tackle that,' says Rosamund Teagle. Rosamund Teagle said they've noticed how meaningful the workshops and website are to people. 'I really believe also very firmly in trans people helping trans people with solving trans problems whenever possible,' says Rosamund Teagle. Rosamund Teagle says it's free to attend the workshop. 'I've heard from the people who have been to these workshops and benefited from my site, that it's meant a lot to them for it to be lead by someone who is also trans themselves,' says Rosamund Teagle. The workshop begins at 6:30 p.m. at Hackforge HQ at 300 Ouellette Ave. Trans, non-binary, gender-diverse individuals and their allies are invited to connect with Rosamund Teagle and learn about the site plus have conversations about accessibility, identity and the power of self-determination. The event will include presentations, a question and answer period and open dialogue. - By Dustin Coffman, AM800

Anorexia is normally treated with therapy. Now a Canadian team is trying the gut

Social Sharing This story is part of CBC Health's Second Opinion, a weekly analysis of health and medical science news emailed to subscribers on Saturday mornings. If you haven't subscribed yet, you can do that by clicking here. Anorexia is a life-threatening eating disorder that can manifest as an intense preoccupation on weight loss. It's classified as a mental illness and normally treated with talk therapy, known as family-based therapy, but that's only effective for about half of the mostly women and girls who have it. Those who don't improve may go to hospital and get locked into a relentless cycle of gaining weight and recovering from malnourishment, followed by weight loss and damage to organs, including changes to the brain from starvation. Now, Canadian researchers are testing a new approach, tapping into the growing understanding of the gut-brain connection. They're going to try treating teens with fecal transplants, to change the bacteria in their gut. "We know that once the symptoms set in and the brain changes, it's really hard to change the course, so if we can intervene early in the adolescent years, we have the best chance," said Dr. Jennifer Couturier, a child psychiatrist and associate professor of psychiatry at McMaster University in Hamilton, Ont. In fecal microbial transplants, a small sample of stool from a healthy person is purified to concentrate the beneficial bacteria minus the waste. The microbiome is then put in a capsule, which the recipient takes for therapeutic purposes. Couturier and her team have Health Canada approval to run a randomized clinical trial in an initial group of 20 females aged 12 to 17 diagnosed with anorexia. They will either take oral capsules along with standard family-based treatment to stabilize nutrition and avoid the harmful effects of starvation or family-based treatment alone. McMaster's own stool bank Fecal transplants have been tested in a small handful of adults with anorexia, including one who restored her weight. In this trial, the McMaster researchers will use the university's own stool bank of donations. Dr. Nikhil Pai, a gastroenterologist at McMaster and a co-investigator on the trial, credited the university's contributions for funding the research and starting the pediatric stool bank. "This is not affiliated with any company," Pai said. "We developed this entirely in-house using carefully screened pediatric donors." Pai said the screening checks for infectious diseases, similar to how blood donations are assessed. Staff at the stool bank then prepare the capsules, which can't be mass produced. WATCH | Exploring the power of poop: There are a few reasons Pai and some other doctors are optimistic participants will benefit. One comes from animal studies. Researchers transplanted gut microbes from humans with anorexia to normal mice models, and found the mice reduced their food intake as if anorexic. Then, when gut microbes from healthy humans were given, the effect reversed. Secondly, young guts are subject to change. Pai said the gut microbiome is malleable in children and teens. "It actually is a very different landscape in adolescence, where if you can make a change, you not only may see some improvement in terms of outcomes for anorexia nervosa in the short term, but … the sustained response," Pai said. Butterflies in the stomach With every meal, trillions of gut bacteria turn breakfast, lunch and dinner into molecules called metabolites that affect the brain. Pai, who also works at Children's Hospital of Philadelphia, said large population-based studies show a few types of bacteria can have an outsized effect on the brain through the gut-brain axis, a connection between the two. "When we feel a bit nervous, sometimes we feel butterflies in our stomach," as a symptom of the nervousness, Pai said. "It's no surprise that we often have these intestinal symptoms that come along with the psychological anxieties." Researchers will follow participants in the clinical trial for eight weeks while they receive the capsules and then for four weeks after that. Pai and Couturier say one aspect they'll record is whether participants are willing to take the fecal transplant — or repulsed by it. Then they'll measure how the patient is doing — by tracking their weight, and mood — and how the microbiome changes based on saliva, urine and stool samples. Gut commands the brain? Scientists are learning more about how gut microbes influence brain function. Various studies have shown people with some psychological problems, including anorexia nervosa, having abnormal intestinal microbes, said Dr. Howard Steiger, former director of McGill's eating disorder program. "We always like to think of the brain as being the command centre for the body," Steiger said. "But you know, a lot of recent findings suggest the gut also controls your brain." In people with anorexia, Steiger said, the thought is that their eating behaviour messes up the way gut microbes influence functions in the brain and body. Given that, transplanting purified fecal samples from healthy individuals could help those with anorexia, said the professor emeritus of psychiatry, who continues to treat people with eating disorders "It's not like total voodoo to think that [fecal transplant] would be a potential adjunct in treatment or maybe even a treatment in itself," Steiger said. Some clinicians now refer to anorexia as a "metabo-psychiatric problem," meaning it is associated with vulnerability both in the brain and the body. "I think that's important because it reduces shame," Steiger said. "People don't develop anorexia because of moral weakness. They carry a real, physical, heritable susceptibility." That means anorexia gets triggered by a combination of nature, or genetics, and nurture, such as life events. Making meal time comfortable Anita Federici, a clinical psychologist north of Toronto, treats adolescents with anorexia using family-based therapy. Federici said initially, the parents or caregivers are empowered to learn how to nourish their child by taking over all meal and snack preparation and supervising intake and weight checks. Then the child might start eating lunch at school unsupervised. In the last phase, the youth regains independence over eating and exercise. About half of younger people with anorexia nervosa who receive family-based treatment for it do really well, Federici said. Change pace of meals? But anorexia rarely "flies solo," Federici said, noting many people also have co-occurring suicidal thoughts or experience self injury, substance use, trauma or PTSD, as well as neurodiversity like autism. All can complicate the picture. Federici said the standard approach of medicalizing treatment for anorexia focuses on gaining weight. Treatment that doesn't take into account the metabolic underpinnings of anorexia can miss the mark, Federici says. "There was research not long ago that demonstrated that there were more serotonin receptors in your gut than there were in your brain," she said, referring to a neurotransmitter with roles including influencing mood. Taking the metabolic basis of anorexia into consideration could mean clinicians may need to change how they feed patients, both in terms of the types of food and the pacing of meals, Federici said. In people with anorexia, the body is dysregulated so they feel soothed when they eat less. While bystanders may think the patient isn't motivated to change, Federici said in reality they're quite motivated. "What I have observed over the years is that these people desperately want to get better. They desperately want a different life, but they need the treatments to be different."

4 people are missing after helicopter crashes on Quebec's North Shore

Four people are missing after an Airmedic helicopter crashed near Natashquan, a community on Quebec's North Shore, around 10:30 p.m. Friday. The helicopter, carrying four crew members and one passenger, was on a rescue operation in the area, according to Raphaele Bourgault, a spokesperson for the company which specializes in medical air transport. One person was rescued and transported to hospital. Their injuries are not life-threatening, according to provincial police, the Sûreté du Québec (SQ). Ground and aquatic search teams are on site to try and find the four missing individuals. "Airmedic personnel are working closely with authorities and first responders to manage the situation and provide assistance," the company said in a statement. The SQ and Canada's Transportation Safety Board are investigating the cause of the crash.
