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.
Any thoughts?
More on Cackling Geese here. More on American Coots here. 
the coot is a cross between a chicken and a duck…a water chicken.
I have no firsthand experience with cackling goose Jim, but I think you’re onto something. The stubby bill looks just like all other confirmed cacklers photos I’ve looked at.
I have limited exposure to cackling geese, but I have pic of one from Rahway. It’s kind of tough without a bird to compare it to. I’ve got a link to the Cackling I have a pic of. Looking at the picture, I’m leaning towards it probably being a canada. Cackling Geese have a more rounded forehead and a stubbier bill. Here’s a side by side to get an idea. Do you have any other shots of him maybe with other geese?
