Believe it or not, Ontario’s Endangered Species Act (ESA) was passed with all-party support back in 2007. Subsequently, of course, it was undermined through numerous exemptions and approvals for harmful activities, and now, through Bill 5, the Government of Ontario is tossing it aside completely. It is being replaced by the Species Conservation Act, 2025, (SCA) which is in no way its equal. With a view to eliminating barriers to development, it is claimed the new law will “help speed up project timelines and provide greater certainty for proponents.”

Devastating Changes

Under the SCA, no migratory birds, aquatic species or species of special concern will be provincially listed. The rationale for removing protections for migratory birds and aquatic species is that they already receive federal protection under the Species at Risk Act (SARA). In the case of special concern species, the provincial government is not listing them because they were not subject to “prohibitions under the ESA”. The provincial government is thus abandoning responsibility for 106 out of the 270 or so species currently deemed to be at risk in Ontario.

National Accord

In 1996, federal, provincial and territorial ministers responsible for wildlife committed to a national accord to protect species at risk by agreeing to “establish complementary legislation and programs that provide for effective protection of species at risk throughout Canada.” Canada and Ontario went a step further in 2011 by developing an Agreement on Species at Risk that commits to coordination and cooperation on preventing species from becoming at risk, as well as protecting and recovery identified species.

The Government of Ontario has abandoned these commitments. Species do not recognize arbitrary political boundaries, and cooperative federalism is absolutely necessary to conserve species at risk, especially amid a biodiversity crisis.

Limitations of SARA

The SARA is not equivalent to the ESA and to date, the federal government has been reluctant to exercise its power under the act on non-federal lands. The Government of Ontario has given no indication that the federal government was engaged on the draft SCA or agreed to step in and provide protections for the migratory birds and aquatic species that have lost provincial protections. On the contrary, Minister McCarthy along with the Alberta Environment Minister sent a letter to their federal counterpart in June, 2025 that requested the federal government amend SARA “to respect the constitutional jurisdiction of the provinces”, along with request to weaken other environmental regulations.

Further evidence that SARA is not fit to purpose to make up for the once gold standard provincial ESA, is that the backlog of species needing reassessment by Environment and Climate Change Canada will grow to 574 by the end of 2030. Additionally, as of 2022, the Auditor General of Canada found that 10% of federally listed species did not have recovery strategies or management plans in place as required by the act. Furthermore, of the 409 recovery strategies prepared by 2022, 20% did not identify the species’ critical habitat, which is necessary for protections under SARA.

Despite the Government of Ontario’s claims that the protections under the ESA for migratory birds and aquatic species were duplicative with federal protections, it is clear that SARA and the federal government are not equipped to provide equivalent protections.

Call to Action

Extinction threatens one million of approximately 8 million plants and animals worldwide. Responding effectively requires cooperation across all levels of government, as previously agreed to under the national accord and Canada-Ontario agreement.

Ontario’s weakening of protections for species at risk threatens our long-term well-being. Join us in urging the Government of Ontario to repeal Bill 5.

With National Volunteer Week now underway, it’s an ideal time to reflect on the role people play in protecting Ontario’s biodiversity. Community science is one meaningful way to get involved. And as spring returns to Ontario, pollinators begin to reappear in fields, forests, wetlands, and gardens making them a natural group of species to observe for community science programs.

While these sightings may feel routine, they are becoming less predictable for many species. Pollinator populations are declining due to habitat loss, pesticide exposure (especially neonicotinoids), disease, invasive species, and climate change. These threats are reshaping where species can survive and fragmenting habitats that once supported stable populations. Getting involved as a volunteer observer is one of the most direct ways to support pollinator conservation in Ontario.

Why Pollinator Sightings Matter

Pollinators — such as bees, butterflies, moths, and even birds — are important indicators of ecosystem health. They support plant reproduction and help sustain food webs across the province and country. Because many species depend on specific plants or habitats, even small environmental changes can have significant impacts.

This also makes pollinators especially valuable for community science. Each observation helps researchers track biodiversity changes across Ontario over time.

Pollinators at Risk in Ontario

Under the Endangered Species Act, 2007, many species at risk received legal protection. However, Ontario’s new Species Conservation Act, 2025, introduced through Bill 5, changes how species are protected and may reduce protections for some, including certain pollinators.

Monarch (Endangered in Canada / Special Concern in Ontario)

Herbicides and insecticides reduce milkweed, a crucial piece of the Monarch’s breeding habitat. Their long-distance migration also exposes them to threats such as habitat loss and declining wildflower availability.

Rusty-patched Bumble Bee (Endangered)

Once common in southern Ontario, this species has declined sharply. The last confirmed observation records in Canada come from two Ontario Parks, Pinery Provincial Park (2009) and St. Williams Conservation Reserve (2000).

Mottled Duskywing (Endangered)

This butterfly depends on rare oak woodlands and plants such as the New Jersey Tea and Prairie Redroot. These habitats are limited and fragmented, making populations vulnerable.

West Virginia White (Special Concern)

An early spring butterfly that depends on Two-leaved Toothwort. Invasive garlic mustard is a threat to this species as it disrupts egg laying behaviour.

Yellow-banded Bumble Bee (Special Concern)

An early spring pollinator of wild plants and crops such as blueberries and apples. This bumble bee’s abundance has decreased in Ontario and is associated with habitat loss, pesticide exposure, climate change, and disease.

Contribute your Sightings

If you spot these or other species, you can contribute to community science projects:

• Butterflies and moths can be recorded through the Ontario Butterfly Atlas and the Butterflies in My Backyard project
• Bumble bees can be reported via Bumble Bee Watch
• Birds via Ontario Breeding Bird Atlas
• Reptiles and Amphibians via Ontario Reptile and Amphibian Atlas

You can also join the global community of iNaturalist users to share and verify observations. The Natural Heritage Information Centre has a Rare Species of Ontario project.

The Ethics of Observation

Observe wildlife responsibly to avoid disturbance and ensure useful data. Follow A Nature Viewer’s Code of Ethics and be aware that many species are protected under Ontario’s Fish and Wildlife Conservation Act and Canada’s Species at Risk Act.

Every observation matters. Whether you notice pollinators in your garden, birds overhead, or frogs in a wetland, your sightings contribute to a better understanding of Ontario’s ecosystems—and how they are changing.

On April 1, Texas’ Fort Worth Zoo welcomed  a 285-pound baby into the world. It wasn’t an April Fool’s joke—the newborn was a healthy male Asian elephant (Elephas maximus) calf, and he represents the newest member of a four-generation Fort Worth elephant family.

Elephants are currently the largest terrestrial animals on earth, and they consist of three species: the Asian elephant, African savannah elephant (Loxodonta africana), and African forest elephant (Loxodonta cyclotis). Asian elephants are a bit smaller than the other two species. On average, they weigh between 6,000 and 12,000 pounds and usually are six to 12 feet tall at the shoulder. Today they exist in limited areas in India and Southeast Asia, and they are classified as endangered in the IUCN Red List, with a decreasing population. 

Fort Worth Zoo’s calf is 36 inches tall and is the offspring of father Romeo and mother Bluebell, whose prenatal care included weekly blood tests, regular physical examinations, and sonograms. He has one full sibling, Travis, and two half-siblings, Lady Bird and Brazos. 

Keeping with the Texas-theme naming tradition, the new calf has been dubbed Sam Houston after the politician of the same name. Houston who was a veteran of the War of 1812 and an important figure in the Texas Revolution (1834–1836). He also played a significant role in helping Texas become part of the United States. While the historic figure’s first name was Sam (Samuel), and last name was Houston, it’s a double name for the young elephant. 

“Given his remarkable size – the largest calf in Zoo history – it felt only fitting to honor one of Texas’ most iconic figures, Sam Houston,” according to a statement. “Like his namesake, the Zoo’s Sam Houston (yes, it’s a double name) represents strength, and a lasting legacy, joining a four-generation elephant family that reflects the rich heritage and enduring spirit of Texas.”

Sam Houston got down to business right after birth. He was on his feet within six minutes of popping out, steering his trunk competently almost right away, and nursing within an hour. Sam Houston made his public debut May 7th after spending weeks bonding with his mother and becoming familiar with his environment—including being near other members of the herd—away from prying eyes. However, zoo  visitors can only see Sam Houston from 11 a.m. to 2 p.m., because afternoon naps are imperative to the baby’s wellbeing and development. 

“Asian elephants are endangered, with fewer than 40,000 individuals remaining in the wild, and their populations continue to decline,” Ramona Bass, chairman of the Fort Worth Zoo Board of  Directors, said in the statement. “Each birth is a step forward, reflecting decades of dedicated care and specialized expertise. As part of the natural world, we play a critical role in their future – and through continued research and innovation, including the Zoo’s CARES Lab, we’re helping ensure Asian elephants thrive for generations to come, right here in Fort Worth, Texas.”

When Sachita Shah sent her cardiologist brother an ultrasound of her patient’s heart, he was very confused. The heart was huge, and the left ventricle incredibly muscular. His confusion was warranted, as the ultrasound was not of a human heart. It belonged to another primate—a gorilla. Shah, emergency physician and VP of Global Health at medical equipment manufacturer Butterfly Network, tells Popular Science that if she had shown an ultrasound of a gorilla fetus to a radiologist, they would have assumed it was a human baby. 

Shah is on the gorilla care team currently looking after Jamani and Olympia, two western lowland gorillas (Gorilla gorilla gorilla) mothers at Woodland Park Zoo in Seattle, Washington. Jamani gave birth on Monday May 18, and Olympia is expected to deliver her new baby imminently. Shah and her colleagues’s work involves conducting ultrasounds of Jamani and Olympia’s baby bump—though now probably just Olympia’s—to keep an eye on the baby’s growth and position. 

“We got a really pretty baby face,” Shah says, speaking of the ultrasounds. “We could see nose and lips and fetal breathing movements and heartbeat and drinking fluid, opening mouth and swallowing. For all intents and purposes, it was very much the same [as a human baby].” 

The endangered gorilla mothers were trained to take part in the exams and procedures conducted by the gorilla care team, and they could choose whether to participate or not. The gorillas put their bellies against the edge of the enclosure for the scan (and received snacks), where there is a small opening through which the care team can reach through with the ultrasound probe. 

As such, the zoo needed a small and portable imaging device. That’s where Butterfly Network and their all-in-one ultrasound probe came in. 

“When you think of an ultrasound, you might think of a big cart with lots of different probes—a different probe if you wanted to do a pregnancy scan, or a heart scan, or a pediatric scan might have a tiny probe,” Shah says. 

Instead, the Butterfly probe they use at Woodland Park Zoo is a handheld ultrasound that plugs into a smart phone. It is around as big as an electric shaver, and it functions with a number of different softwares for either veterinarian or human health use. Notably, an app allows the team to use it for different types of scans—from a pregnant gorilla to a child’s lungs—that would traditionally require distinct probes and machines. 

Shah and her colleagues also used the Butterfly ultrasound device to scan the heart of Nadaya, the silverback gorilla father of both babies. In fact, the heart ultrasound Shah sent to her brother belonged to Nadaya.  They used human software for that scan, even though their vet software is optimized for fur. Fortunately, Nadaya’s chest isn’t very furry. 

Shah, who has gone through a pregnancy herself, was most moved by working with the gorilla mothers. 

“We could tell the baby’s head had dropped and we thought, ‘oh man, she must be so uncomfortable.’ And she was waddling and walking a little differently. I was like, ‘oh, I remember that, girl.’ It was just amazing to remember that we’re all connected in that way,” she says. 

Western lowland gorillas are critically endangered, so babies are always excellent news.

UPDATE May 27 8:19 a.m EDT

On Sunday, May 24, at 1:44 p.m. PDT, Olympia’s baby was delivered by an emergency C-section performed by a medical team who typically works on humans. This 5.4-pund boy is the western lowland gorilla’s second baby.

On April 21, a baby horse was born at the Wildlife Conservation Society’s Bronx Zoo in New York City. But it wasn’t just any foal that came into the world—this newest resident of the Big Apple is a Przewalski’s horse (Equus ferus przewalskii), an endangered species that has been pulled back from the brink of extinction. 

Przewalski’s horses look more like a mule than your average horse. For starters, their mane sticks up straight into the air and they don’t have a forelock (horse bangs, basically). Przewalski’s horses are also short, light brown, and—excuse the necessary slang—exceptionally chonky. They also have a really thick neck. 

They are also referred to as the Mongolian wild horse, and they are the only truly wild horse species left, according to the International Union for Conservation of Nature (IUCN). Though the species used to exist across Asia and Europe, their numbers plummeted so much that at one point they were deemed Extinct in the Wild. 

“The Bronx Zoo has played a pivotal role in the conservation of Przewalski’s horse,” the Bronx Zoo wrote in a statement announcing the birth. “Through breeding programs aimed at maintaining a genetically diverse population of the species and through reintroduction efforts, zoo-bred Przewalski’s horses were successfully returned to their native grasslands in China in 1989 and in Mongolia beginning in 1992.”

Przewalski’s horses now live in Mongolia, China, and Kazakhstan, as well as in zoos. Rather shockingly, the entire extant population (which researchers estimate is less than 2,000 individuals) descends from only 12 horses. 

In Mongolia, the Wildlife Conservation Society supports Protected Areas with wild horses. As for the Bronx Zoo, the foal is part of a herd. Visitors can see it from the Wild Asia Monorail, where the adorable baby is sure to develop a colt (young male horse) following.

Previously, we reported on the birth of a baby western lowland gorilla (Gorilla gorilla gorilla) at Seattle’s Woodland Park Zoo on May 18. His mother Jamani was one of two pregnant western lowland gorillas bearing children from the same father, a silverback gorilla named Nadaya. Since Olympia was due around the same time, we spent the long weekend waiting anxiously for news. 

The Woodland Park Zoo’s announcement arrived last night. The baby was born on May 24—five dates past the due date. To bring her baby into the world, the medical team that usually works on humans performed an emergency C-section on Olympia. The procedure is incredibly rare for gorillas, with less than a dozen recorded gorilla C-sections.

“Over the weekend, the decision to proceed with emergency delivery was due to low fluid and intermittent low baby heart rate (found by us with the Butterfly) and critical behavioral information from the keepers team that suggested delayed/paused labor, with confirmation of ruptured membranes (bag of water) by the Team Gorilla OB physicians,” Sachita Shah, emergency physician and VP of Global Health at medical equipment manufacturer Butterfly Network, tells Popular Science. In a previous interview, Shah said that ultrasounds of gorilla fetuses look very similar to ultrasounds of human fetuses. 

Butterfly is an all-in-one ultrasound probe that the gorilla care team has been using to monitor the pregnancies. Once the baby came out, “I used The Butterfly throughout the neonatal resuscitation to keep a close eye on the baby’s heart rate as our vital sign so we were able to ensure the safe point to transition from neonatal resuscitation to post natal care,” Shah adds. 

Whether for humans or gorillas, a C-section is a major operation, and Olympia rested without the baby for the first night after the birth. But the newborn wasn’t far away—a gorilla keeper and veterinary technician took care of the baby in a den next to Olympia’s, so she was able to see, hear, and smell it. Both Olympia and the baby boy are now back with their gorilla troop, though Jamani is taking care of Olympia’s newborn as well as her own baby boy. 

“So far Olympia’s baby is doing well and maintaining a healthy body temperature. While Olympia recovers from the C-section, our plan is to allow Jamani to continue caring for Olympia’s son while also caring for her own son as long as both infants remain healthy, which is our priority,” Martin Ramirez, Curator of Mammalogy at Woodland Park Zoo, explained in a blog post. “Once Olympia shows signs of being ready for her baby, we’ll move forward with plans to reunite them.”

It remains to be seen what the mother-son duo will look like. However, western lowland gorillas are critically endangered, so the important thing is that both remain healthy.

How do you determine how many months or years animal mothers nurse their babies? If you’re not in a rush and can observe this dynamic, you could supposedly stick around to see when the baby, mother, or both decide that they’re done. However, that could take years. A team of researchers investigating breastfeeding in orangutans recently opted for a different, perhaps surprising strategy—searching for particular proteins in poop. 

In a preliminary study published in the journal Communications Biology, researchers searched for milk‑specific proteins in the feces of wild Bornean orangutans (Pongo pygmaeus) living in the Danum Valley Conservation Area, in the Malaysian part of the island of Borneo. These proteins prove that he or she is continuing to drink breast milk.The practice of recognizing particular proteins in feces is called fecal proteomics and it can help scientists better understand what animals are consuming.

“Orangutans have a slow life history with one of the longest interbirth intervals and the lowest reported infant mortality rates among primates or even mammals,” the team wrote in the study. “Breastfeeding is a key factor in their life history because it possibly promotes offspring health and increases maternal interbirth intervals.”

The team gathered fecal samples for over two and a half years, and found milk‑specific proteins in all the 20 samples from orangutans less than six and a half years old. This indicates that the young great apes were continuing to breastfeed until they were at least that age. 

According to the team, these results are “consistent with the behavioral evidence as having one of the longest breastfeeding periods in mammals.”

What’s more, “milk intake was significantly correlated with higher levels of biological defense and probiotic bacterial proteins.”

In other words, the more milk a young orangutan drinks, the more probiotic intestinal bacteria it has and the sturdier its biological protections are. Such consistent and enduring breastfeeding probably helps the very high survival of orangutan babies and plays a role in their slow reproductive approach. 

Unfortunately, Bornean orangutans are critically endangered, and the paper highlights why their populations don’t rebound quickly after a decrease. Safeguarding what’s left of their rainforest habitats is crucial.
