Dive-bombed or not, Vancouverites still pro-crow, researchers say
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 BC'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 BC 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."

Trying to lose weight? Ethnicity might matter — and the differences point to a larger issue, study says
Considering joining a weight-loss program? Your ethnicity may have more of an effect on your success than you'd think. A new study from York University researchers suggests Black, Latin, Middle Eastern or South Asian people may lose significantly less weight in clinical programs compared to White, East Asian and other ethnicities. 'We know that in terms of obesity rates, there's large differences between ethnic groups,' said Jennifer Kuk, the lead author and a professor at York University. 'So we thought it's important to look at whether or not there are differences in the weight loss achieved as well.' ARTICLE CONTINUES BELOW Life Counting calories and cutting out fats? Why these common diet mistakes can do more harm than good The internet is rife with potentially dangerous misinformation around dieting, experts say. Here are some to look out for. Life Counting calories and cutting out fats? Why these common diet mistakes can do more harm than good The internet is rife with potentially dangerous misinformation around dieting, experts say. Here are some to look out for. Her team's results imply the ethnicities at greatest risk for obesity also stand to benefit the least from traditional weight loss programs, Kuk told the Star. She believes the reason lies in socioeconomic and cultural differences, from lack of access to private health insurance to generational trauma. 'I think it's a very important study,' said Robert Ross, a professor of exercise physiology at Queen's University who is unaffiliated with the research. 'It recognizes that referral and access to treatment programs varies across ethnicity.' The paper was published this week in peer-reviewed journal Clinical Obesity. Here's what you need to know. Ethnic differences in weight loss The retrospective study reviewed the weight loss journeys of 14,695 people enrolled in clinical weight management programs across southern Ontario. Each participant was asked to self-identify their ethnicity into the following broad groups: white/Caucasian, South Asian, East Asian, African Heritage/Black, Indigenous or a free-form field that would be categorized as Latin, Middle Eastern, Mixed or Other. Among all the ethnic groups, white people experienced the most weight loss, losing an average 4.9 kilograms. East Asian ethnicities lost an average 4.3 kilos, while 'other' ethnic groups lost 4.4 kilograms on average. ARTICLE CONTINUES BELOW ARTICLE CONTINUES BELOW In comparison, Indigenous people lost an average 3.9 kg, South Asians lost an average 3.5 kg, Black individuals lost 3.3 kg on average, Latin ethnicities lost an average 3.0 kg and Middle Eastern people lost 2.7 kg on average. Life Are most diets doomed to fail? Here's what experts say actually works for weight loss Despite the hype around so-called 'yo-yo diets,' experts tell the Star only the rare exception will see long-term results. Life Are most diets doomed to fail? Here's what experts say actually works for weight loss Despite the hype around so-called 'yo-yo diets,' experts tell the Star only the rare exception will see long-term results. When Black people were further asked to identify as African American, African Black or West Indie Black, it was found African Americans lost the least amount of weight out of all the groups — averaging 1.2 kg of weight loss. Prior studies show Black individuals also tend to have the highest obesity rates in Canada. Ross was surprised to find about a third of all ethnicities discontinued the weight loss program after just one visit. Indigenous people are most likely to discontinue, with 41.9 per cent stopping the program: 'I think that underscores some of the challenges we have in addressing obesity,' he said. Why is this happening? The study didn't delve into why these differences exist — it merely tracked how much weight people of each ethnicity lost. But previous research offers some clues. Kuk noted that systemic racism, which can lead to unequal job opportunities, educational disparities and wealth inequality for certain ethnicities, can also result in food insecurity and hamper the ability for people to eat a healthy diet. Similarly, different ethnicities have significant disparities in access to health care. Indigenous, Black, South Asian and Latin individuals are less likely to have access to a regular health provider compared to the general Canadian population, for example — meaning less access to clinical weight and obesity management. ARTICLE CONTINUES BELOW ARTICLE CONTINUES BELOW Kuk added that generational trauma could modify one's genes in a way that predisposes their children to obesity, even if these children never experienced that trauma themselves. Health Canadian preschoolers get nearly half of their daily calories from ultra-processed foods, study finds. What should parents do? The U of T study found that nearly one in five of the more than 2,000 children they followed over a five-year-long study was overweight by age five.

The U of T study found that nearly one in five of the more than 2,000 children they followed over a five-year-long study was overweight by age five. 'Thus, factors such as racism, immigration, and lower wages may also contribute to (genetic changes) that may contribute to obesity or impair obesity management,' the study read. But Ross notes that, due to the nature of the study, we don't know exactly why this is happening. More research is needed to further understand this relationship. How does Ozempic factor in? The study was performed near the start of the advent of Ozempic, right when similar weight-loss drugs hit the mainstream. The paper noted there were no ethnic differences in the rate of Ozempic prescriptions. That said, it had no data on how many of these prescriptions were being filled, how long they were in use or how effective the drugs were. Kuk noted that Ozempic and other effective obesity medications present another barrier to care for certain ethnicities. These drugs are not often covered by health insurance, forcing patients to pay out of pocket — 'compounding the ethnic differences in terms of salary, private health insurance access and so on,' Kuk said. In Canada, data show Black and Latin individuals have among the lowest income of all other ethnicities. They also have some of the highest obesity rates: 'This is just making it even harder for the groups that potentially need obesity treatment the most,' Kuk said.
