This fall, I observe different species of birds passing through the Toronto Brickworks. First, I saw finches:

Then the American tree sparrows:

It’s not like the birds book a reservation in the quarry. There’s plenty of overlap as one species checks in and another checks out. Here’s a common starling:

Over the past week, I’ve been watching the mallard ducks:
