Thanks for all the responses!
Walter, I went by the Martin house yesterday morning and found it vacant, though there were lots of swallows and swifts over Grenadier Pond at that time, so if there were occupants, they could have been hawking over the pond.
stvgarrett, Indigo Buntings are in various locations-- most reliably on the path leading S from the TTC turnaround at the terminus of Howard Park:

ravynne40, thanks for adding to the list of potentials-- I, too, saw Red-tails, Blue Jays and others earlier in the year, but not since July 1.
pacharo, this isn't a great time of year for photos, unfortunately-- the birds in the list have mostly been seen high up, obscured by leaves, or just heard. The beach and Grenadier Pond should be good for pictures, though. The Herons and Egrets were on the breakwater just E of the white pedestrian bridge across the Humber River, and the Cliff Swallows have a large colony under the bridge. Ducks mentioned were at the E end of the beach and not too skittish-- there are Wood Duck juveniles near the rushes at the N end of Grenadier Pond. Dawn is best for the waterfront; afternoon for Grenadier Pond.
Black-crowned Night Heron and Great Blue can also be found in the two duck ponds SE of the zoo:

http://maps.google.com/maps?q=43.652705 ... num=1&z=16Again, they often stick to shade. I've seen three Nighthawks over Roncesvalles near Dundas St W most evenings; same for Chimney Swifts. Swifts were in great numbers over Grenadier Pond yesterday AM.
NB: Many of the paths are overrrun with Poison Ivy, so it may be wise to stick to wider thoroughfares. The off-leash dog paths are good for listening in the afternoons... it stays pretty cool, too.
