Looks like double-crested to me. Scott

Yes, that was sorta the point...OP asked which owl? Humour fail. Scott

Just trying to add a little humour. Which Owl / Witch owl. Sorry if I offended. Scott

This is a which owl.

Ravens for me as well. Scott

Millipede, I think the point is to start with the expected. If you see something that makes you wonder, then pursue it, but don't declare zebra just because you see a horse with a funny tail. It better have stripes as well. So is there anything in this immature bird, like white right to the bottom of the eye, or lack of brownish tones in the grey? No, this bird has black all around the eye and subtle brown tones here and there. So, it's a horse not a zebra. Scott

I think you're right about the tail TBN. I was able to reveal a little more data by adjusting light levels. The head does look reddish, crested, long-billed, and there's a hint of white in the chin throat area. I would agree with merganser. Scott

Hmmm.....even with those pale primaries? Here's another view after they all shifted around.

Sure looks like one. Back already! Scott

Thought this was a first winter iceland based on size and bill, but someone listed a glaucous near here so I want to confirm. Taken yesterday i Peterborough, Ontario.

Thanks guys. I was quite certain once I viewed the photos, but there was some uncertainty in the field. Scott

Taken today in Peterborough, Ontario. One is clearly a common. Does everyone agree the other is a red-breasted? Scott

Looks good for greater. Scott

Thanks for the date. As said before, this is a spotted, partially or fully into basic (winter) plumage. Scott

The male gets that white patch from a white "hip", whereas the female's white comes from the secondaries. Other males have white hips (wigeon), and other females have white secondaries, (gadwall), so no you can't rely soley on the white spots in the rear view to id a female pintail, especially since those secondaries are not always visible. Instead, look for that smooth, warm, unmarked head with a grey bill. Scott

Do you have photos with their bill out of the water? I probably can't help with certainty, but the bill and throat are useful in separating the two. Scott

Yellow-rumped warbler, audubon's, first winter. As mentioned, the small throat patch makes it audubon's. The fact that it's white suggests first winter. Scott

Looks right for laughing. Scott

Besides the tiny recessed head, the tail feathers are all the same length, so that even with the tail spread it looks more squared than rounded. I based my RSHA id on the buteo shape and the thin white lines on the tail. Scott Edit, oh wow! I.just realized I originally said cooper's. No, I clearly wasn't seeing it right. RSHA for me.

Thanks. Sorry I messed up on that one. Scott

I agree. A very light individual. Scott

The only thing I can come up with is third winter lesser black-backed, but I would have expected yellow legs by that age. Wait for someone with more gull expertise. Scott

1. Can't tell where the bird ends and background starts 2. Orange-crowned warbler 3,4. Sharp-shinned hawk 5. Agree with juvie MODO 6. Cooper's if I'm seeing it right. 7. I think you're right with least...maybe.

Lovely comparison shot of the two species. Scott

Is this orange-crowned warbler closer? https://www.google.com/imgres?imgurl=https://cdn.audubon.org/cdn/farfuture/ImrdEUhfivKDsN2jRISF1nZieHwUO0cseyemMtRXs1g/mtime:1548778019/sites/default/files/styles/grid_gallery_lightbox/public/Orange-crowned_Warbler_s52-8-112_l_1.jpg%3Fitok%3Ds8acHz-l&imgrefurl=https://www.audubon.org/field-guide/bird/orange-crowned-warbler&h=820&w=1024&tbnid=RiLijPxVbsE3OM&tbnh=201&tbnw=251&usg=K_WWpGrIxzHFTMQx9BFMdyrfkW0HQ=&docid=oQdbnH1J4A5m3M Scott
