June 22 to 28 is Pollinator Week! We're celebrating with a look back at the grand opening of the Humber Bay Butterfly Habitat in 2002. Overlooking the native plants is one of the 'Guardians', a series of sculpted ravens by artist Amy Switzer. https://ow.ly/C4Fg50Z7Akm

“Had it not been for challenges like climate change and 200 years of visiting tourists compacting the soil around it - the tree could have lived for hundreds more years, as trees "do not die of old age".

Rode 90 km today using the Humber trails to get to Claireville Dam where I spotted a Bald Eagle! Had lunch at Humber Arboretum, lots of frogs! Zipped back to the lake, east across the waterfront, north on Portland bike track (love!!!) & Shaw back to midtown. #cycling #toronto #bikeTO

Fly #fishing on the Humber River, Claireville Dam, rail track overpass as a #train moves thru, Humber Arboretum. These too, could be yours, if you #cycle the Humber Trail, #bikeTO, #walkTO. Not pictured: rabbit, baltimore oriole, 3 species of swallows, yellow warbler, goslings, ducklings, turtles.

At #WBF26, @beckyck.bsky.social makes a powerful point! We know a lot about ecosystems decline, but we must also dedicate equal energy to uncovering the secrets behind successful recovery. Let's inspire action for biodiversity and science-driven solutions! #Biodiversity #ScienceForRecovery

Good morning from Summerlea Park in northwest Toronto. Today I will be following the Humber River from where its east and west branches meet down towards Lake Ontario. Let's go. #metroscapes

We had a lovely walk and workshop for Earth Day all about using the citizen science platform iNaturalist. Two teachers brought their classes and the kids had a blast - and so did we! 🌞🐢 The weather cooperated wonderfully, and the Midland Painted Turtles helped by striking poses like this:

It's a gorgeous day for our Camp Family Fun Day, where families who have a camper registered for summer were invited to visit together and bring friends for a little taste of #NatureCamp activities. Families were able to enjoy nature hikes with Flicker...

It's the start of National Wildlife Week in Canada and the start of spring migration, so it's the perfect time to make sure your windows are as bird-friendly as they can be. This great poster by @rosemarymosco.com summarizes the problem of window collisions; learn what you can do at birdsafe.ca

Yesterday we took a nature walk in honour of World Wildlife Day, and although we were clear with the participants that we could make no promises, the wildlife turned out to be very cooperative! We were only just leaving the garden area when a coyote strolled by (but did not stop for photos): 1/4

BLACKBIRDS! February 28, 2026. Starting my #SpringMigrstion watch now (though the snow buntings last week might’ve counted…) Saw my #FOY blackbirds at Humber Bay Park West. They weren’t posing for portraits, of course. Hungry and tired after crossing the lake, but singing and calling in the brush.

We still have spots available for March Break Nature Camp at the Humber Arboretum! Get your kids outside to embrace the wonder of the changing seasons. Ages 6 to 12 $405 for all 5 days Located behind Humber Polytechnic North Campus in North Etobicoke, #Toronto humber.ca/arboretum/le...

The #BizBiodiversity Assessment is the first of its kind to help align the economy with nature. 🌍 As @ipbes.net ES Dr Luthando Dziba says “It’s about understanding both the dependencies and impacts of business on biodiversity—and turning that evidence into action.” 🧪#IPBES12 ipbes.canto.de/b/HJAGG

Kudos to @humberpoly.bsky.social Journalism student Mason Kossak for covering the change of the Doomsday Clock. The accelerating climate crisis is one of the factors over which scientists are sounding the alarm.

We're all set up with Daybreak on the table and Groundhog Day on the TV. If you're at Humber North Campus, drop by the 3rd floor of the LRC until 1:30 PM to say hi!

Last week's attempt at a Daybreak drop-in was thwarted by a snow day, so we're trying again this Monday February 2. Drop by the 3rd floor of the Humber North Campus Learning Resource Commons from 10:30 AM to 1:30 PM to play the cooperative boardgame and explore resources. humber.ca/arboretum/ev...

A sad loss for Canada. Kirsty Duncan was always a great fan and supporter of the Arb, not just as the MP for Etobicoke North, but as an individual who was passionate about nature and science. We send our condolences to her friends, colleagues, and family. www.cbc.ca/news/canada/...
