Have been finding some great stuff on the Urban Biodiversity Facebook Group (Toronto) page:
From last summer:
Discover the "butterflies of the night" at the annual High Park Moth Night with the Toronto Entomologists Association. TEA leaders (Dave Beadle, Tom Mason) and members will set up special lights and help us identify moths. Meet at the benches across from the Grenadier restaurant at 8:15 pm. This outing is especially good for children - bring the whole family! Please bring flashlights, insect containers, moth guides if you have them.
And this recent video of a Starling Murmuration at Yonge and Dundas:
