A great birding spot, if you hit it right, is the Gunnell Oval area of the Kearny Marsh.
The other day the marsh was chock-a-block with American Coots (above), Canada Geese, Mallards and Northern Shovelers.
We also caught a glimpse of the Common Moorhen and what we suspect was a Cackling Goose (below) -- the smaller cousin of the Canada Goose.
This guy was smaller, and shorter-billed than his companions, but it was a tough call.
