Clark's Grebe

An interesting day at Fernhill Wetlands today. The migrants were pretty much gone. I saw no Western Tanagers, Yellow Warblers, Wilson's Warblers or Warbling Vireos. I didn't even see any Yellow-rumped Warblers or Savannah Sparrows.
But there were other fun things to see such as a Greater White-fronted Goose, some hybrid Canada Geese (domestic Greylag x Canada Goose), Virginia Rails and three Clark's Grebes as seen above.
The Grebe's stayed out in the middle of of Fernhill Lake for most of the morning while I was there, but one ventured reasonably close to shore for a bit. It was kind of fun as while it was feeding under water, I would reposition myself where I thought it would surface. Take a few shots and then repeat the process. Eventually it rejoined the other two well out of reach of my lens.

Clark's Grebe?

When I saw the Grebe above, I assumed a Western Grebe as it seems most I see are. Looking at these pictures again tonight, I've swayed myself into thinking that it is a Clark's Grebe. It's harder to tell them apart in the winter as the Western Grebe gets a little smudgy around the eye and the Clark's Grebe darkens above and to the sides of the eye, but I'm going mostly on field guide information than on experience.
Bill color is also an indicator, but isn't much help in this case, in my opinion, as the bill looks bright yellow in the sun and dark when it is shaded.
What's swayed me is the fact that the eye is only half covered with black, with some smudginess of the black around the eye. I may be wrong, I have been before, but that's my conclusion. As always, comments welcomed.

Clark's Grebe?

I've seen both Clark's and Western Grebes here at Fernhill Wetlands for a month or two, but they have always been out in the middle of the main pond. I could only get pictures good enough for identification, but otherwise they were pretty poor.
On Sunday I had a little better luck. This Grebe was fairly near the pond's south bank. Unfortunately, I was a little east of it so the sunlight was hitting it from the back and side. I tried to get to the west side of it, but as I moved, it would dive under water only to surface even farther west. We went through this sequence about four or five times before it started moving towards the center of the pond. Note the fish in its beak in the bottom image.

Now the hard part. Is this a Western or Clark's Grebe. At first I decided it was a Western as the eye is surrounded in black; a Clark's Grebe's eye is usually surrounded in white. But we are well past the breeding season and the Clark's winter plumage will darken around the eye. It is the pronounced white streak on its lores that finally made me decide this is a Clark's Grebe. I'm not totally convinced, but that's my best guess.
