Glen Haffy C.A. and a Backyard Cooper’s Hawk: Late Dec. 2021

I last visited the Gen Haffy Conservation Area near Mono Mills in June 2020.

Here are some photos from that day:

Glen Haffy is located within the Humber River Watershed, at the junction of Ontario’s two most dominant geological features – The Niagara Escarpment and the Oak Ridges Moraine. 

Here is how it looked on an overcast December 2021 morning:

O World, thou choosest not the better part!
It is not wisdom to be only wise,
And on the inward vision close the eyes,
But it is wisdom to believe the heart.           – George Santayana (1863–1952)

    Happy New Year to you Miles.
    Thank you for all your posts which you have faithfully produced every day of the year. I read them every day always learning something new. I have learnt mostly how to differentiate all the different ducks and am amazed at how many different varieties we have here in Ontario. I need a quiz to be tested on all these ducks. I have learnt a lot about the different sparrows and finches but still find some of them indistinguishable and am amazed that you can always spot the sometimes small difference between them.
    May you continue on your walks in 2022 but with a group.
