Hello,
I finally joined this community and I thought I would give you an update on what I've seen in the Brickworks and Don River/Don Valley area over the past few weeks.
This week has been pretty active.
Two nights ago we saw three black crowned night herons (and possibly a fourth in the trees) fishing in the Don River just north of Pottery Road. We took some pictures but it was dusk and they are grainy. I may post later.
Today we saw a hooded merganser swimming just south of Pottery Road in the Don River. I managed to get 1 picture of it as did my fiancee, but it and the other mallards it was with flew away.

There appear to be 3 red-tailed hawks living near the Brickworks. Two of them seem to hunt together and the third occasional hunts with/near them. Only seen them in the air above the high escarpment at the Brickworks. The first link is from today and the second link is from 3 days ago:


We saw one on the path 3 weeks ago and got some good pictures:

There are a few pairs of belted kingfishers playing tag in the trees around the Brickworks. VERY hard to get a picture of. This is the best I have:

Some cormorants have made their way to the Brickworks and are swimming with the Canada Geese and ducks. This guy was posing for a few people today:

Also, there are a lot of red-winged blackbirds (seems like more than last year) at the Brickworks:

I've seen 3 or so downy woodpeckers in the trees around the Brickworks. This one got very close to me:

Yesterday, i lucked upon a pileated woodpecker on the upper escarpment. I managed to take 2 pictures before he took off, but it flew away before I got anything decent (so i have nothing to show).
a red-bellied sapsucker almost flew into me last week as well.
I update my flickr account weekly, and since I live near the Brickworks, you will be seeing a lot of updates until May (vacation time!)
Hope this update helps!
