"Third-year psychology student at the University of Guelph-Humber, Dani Agosta ... said they wished more students knew the Arboretum existed. 'I guess they just don’t come to this side of campus, but it’s honestly really unfortunate because it’s one of my favourite places to be,' they said."

Beautiful Red Oak for #ThickTrunkThursday. Found in Sandy Cove Park in the nearby city of Barrie Ontario, Canada, it is nice to see these survivors. 🌳

The wading #birds were having words. Landscape Technician Lucas caught this moment during a dispute between a Great Blue Heron and a Great Egret. The heron, who's a regular, would swoop at the egret every time the new bird tried to land in the pond. Really folks, there's enough fish to go around!

Smoke from wildfires have turned Toronto an eerie yellow today. The Nature Campers went in to the college for lunch and some activities due to the poor air quality. This is just one impact of human-caused climate change. The view this morning, before and after adjusting the camera's white balance:

Set-up on the grass, a large banner for Soper Creek Wildlife Rescue features five photos of animals and the words rescue, rehabilitate, release, educate, and conserve. A number of furs and skulls have been laid on the grass in front. The whole scene has a yellow tinge to it.

A nearly identical photo to the first, except the camera has eliminated the yellow tinge. It creates the (false) impression of a normal, albeit overcast, day.

Yesterday the Nature Campers made some brilliant bird collages using mixed media. 🐦✂️ #Art #SummerCamp #Toronto

A child holds up a kiwi made out of cut-and-glued paper. Unlike the other collages, the kiwi is not attached to a larger sheet of paper; they just exist in the world all on their own.
