Ah, I didn't realize that you were referring to Humber Bay. I presumed you were talking about the Humber trail ... along the Humber River …. somewhere exotic. I know Humber Bay, East quite well. I often walked there after visiting High Park starting from the High Park subway station and then hiking down the park and then over to Humber Bay. So, with that straightened out, when you mean the pond I must now conclude that you were captivated by the land-locked body of water at the eastern half of Park East. The one usually surrounded by tall grass and rushes, making it very hard to see the water except at the culvert where there is a gap in the vegetation. I have often seen HM in that pond but I could never get to them. They are also sometimes in the lagoon that has a causeway-type deck running east-to-west across its length. You can shoot to either side but can't get right down to water level. You can also shoot from the rocks adjacent to the small bridge. From the rocks you can get somewhat closer to the water. I’ve sat on those rocks many times during the winter getting as close to the water and ice as I could. I mentioned that spot in a blog I wrote about Romancing the Isthmus. There is also a very narrow isthmus between the east bay and the south bay (surrounded by land on three sides and by a narrow peninsula on the north side). This protected bay connects to the one of the eastern bays by a narrow isthmus, one on either side of the northern berm (so it’s not really a true peninsula) and water fowl must swim through these narrow gaps to get into the protected bay. Either that, or fly in. If you station yourself close to water at these choke points you can sometimes get close to birds. With only 200mm it is one of my only options.
