Agreed. Big bills too.

Greater for sure. Nice pics.

I think greater too. Looks like big water which tends to have greaters more than Lessers.

While the first pic is lacking the peak on the back of the head, I'm leaning lesser. The bill looks thin, and there are no cheeks. The eye position and relative size also have me thinking lesser. I second the second pic being lesser.

Yep, agreed with all, and agree with certainty. While there is a bit of a point on #2, the bill and cheeks are huge, which tells me greater.

I need to ask what it is feeding on? Sweet potato? Just curious....always looking for a winter food besides suet.

Agreed with long-billed. The feathers on the wings have Buffy edges that travel all the way up the feather...short-billed have the buffy area limited to the tips. ...that's my tell anyways. Mike

Yep...lesser. Looks like a textbook peak on the back of the head.

What shape is the bird? Robin like? Heron like? What about size?

If you live near water, I'd guess it was a common gallinule.

I'd say short billed. The Buffy tips go up the sides of the feather. In long billed, the Buffy colour is limited to the tips.

White tip of tail is relatively broad, and rounded. It also "seems" chunky, which has me leaning Cooper's.

Another for lesser: very pronounced peak on top of the head, and proportions have a "smaller" feel.

Not a deal breaker in my opinion. They still look like greater to me.

Leaning long-billed. The buffy tips of the feathers are broad, and limited to the tips. The buffy tips on short-billed extend up the sides of the feather.
