  1. Welcome to Whatbird! I'm no expert on these, but it does seem to have a dark throat and a lot of marking on the side of the breast for an Eastern, so I'd guess abieticola is a reasonable possibility. Your reviewer will probably have some thoughts, and if you're on Facebook, you could try the Raptor ID group or the Red-tailed Hawks of the United States group (a lot of the same people). And I agree in hoping @chipperatland others will comment.
  2. A weird one. Here's another one with a black bill, but not quite as weird. https://feederwatch.org/community/participant-photo/american-robin-51/
  3. I like the Coop theory--body thickest in the middle, tail looks long, outer tail feather looks shorter than the others.
  4. A woman posted on the Raptor ID group on Facebook that someone had flagged some pictures from her earlier checklists. The one she asked about was from Wisconsin. So you're not the only one.
  5. Actually, I tried to flag one last year and couldn't. @DLecy told me you need to have uploaded 100 complete checklists in the previous year to be able to flag. If you're an almost compulsive eBirder, you qualify. (For the continuing saga, see https://forums.whatbird.com/index.php?/topic/30064-reporting-misidentification-at-ebird/ )
  6. Sure. I'm not questioning the ID any more. I'm supporting my claim that some aspects of its plumage are quite (maybe downgraded to "pretty") unusual.
  7. I looked at this article from 1989 https://sora.unm.edu/sites/default/files/journals/wilson/v101n01/p0001-p0010.pdf which studied 29 wintering Bald Eagles in Maine and the Maritimes known to be about 2.5 years old. None of them were described as having heads that were mostly white. The comment on rectrices at this age was that the distal 1/3 was dark; no exceptions were mentioned. No birds with largely white breasts were mentioned at this age or any. I also looked at a bunch of pictures of Bald Eagles. Here's one with a lot of white on the wing linings and the tail (more than 2/3), but it has a mostly dark head. https://www.birdsasart-blog.com/2023/04/25/on-photographing-juvenile-bald-eagles/comment-page-1/ (scroll down). Here's one that seems to have a lot of white on the side of the breast, though maybe that's "wingpits", and the lighting seems even more deceptive than in @PaulK's picture. https://macaulaylibrary.org/asset/614533716 It still doesn't give the impression PaulK's picture does (which I don't think can be just a lighting effect) of a partly white breast and a dark belly. So I think both combinations I mentioned--mostly white wing linings with a mostly white head and tail (just thin dark lines), and considerably more white on the breast than on the belly--are far from typical, and I don't think I was wrong to call them "quite unusual". Well, maybe "pretty unusual" would have been better. Would you say either is found above the 1% level at this age?
  8. The head, as well as the tail, is quite different. The plumage pattern of the wings is what made me think first of a Bald Eagle. Your picture does show that I was wrong about the head and tail proportions. @Charlie Spencerand @Averymust be right that the angle of the bird is foreshortening the wings. The outermost primary, which is short, must be invisible (or barely visible?) in these pictures. The combination of extensive white on the head and tail with extensive white on the wing linings, and the combination of a white breast with a dark belly, seems to be quite unusual.
  9. I jumped to Bald Eagle too, but is the tail too long? Are the wings too short? Wouldn't we be able to see the bill even at this distance? And it doesn't have six emarginated primaries (though on the right wing, the lower one in this picture, one primary seems to be missing). Whatever it is, I feel sure the plumage pattern is aberrant for the species.
  10. When I worked at a magazine, including proofreading, I found out that writing in big letters is surprisingly ineffective at helping people notice things, especially if the big letters don't look like the main text. You may have to just put the date and location into your text every time.
  11. Interesting combination of adult tail and juvenile iris. I agree with abieticola because of the dark throat connected by "dribbles" to the belly-band, which looks heavy and blobby. Don't know if there's a way to rule out calurus other than range--which is New Jersey?
  12. I've never looked at cheek color in the field, but I think it can be quite clear in photos. On the other hand, as @lonestranger's quotation says, rufous cheeks don't eliminate first-year male Coops. Nobody has mentioned the flat head and forward-placed eye, which suggest Coop, or the big eye or broad-shouldered shape, which suggest Sharpie--I think. I'd lean toward Sharpie. It might be interesting to see what the experts at Facebook say.
  13. As I understand it, hybrid vigor occurs in hybrids between purebred domestic varieties. Crossing them reduces or eliminates inbreeding depression. There are a few cases where interspecies hybrids are bigger than their parents. Ligers, offspring of a male lion and a female tiger, are typically bigger than their parents, whereas tiglons are not. To judge from Wikipedia, the reason isn't known, but it seems to have something to do with interactions between genes--maybe growth-limiting genes are activated only in female lions and male tigers, so ligers don't get them from either parent. Or something like that. It's not hybrid vigor, as ligers tend to be less healthy than lions or tigers. So it's possible in principle that Greater White-fronted x Canada could be bigger than either parent, but it wouldn't be the result of hybrid vigor. Of course I go along with @DLecy that a big fat hybrid goose (or duck), with oddly placed white too, has domestic ancestry.
  14. Much more likely than Yellow-nosed on the basis of range, I see.
  15. With its dark wings and back and the white had, I'd look at the mollymawks, Thalassarche, such as the (Atlantic) Yellow-nosed Albatross--a juvenile with the apparently all-black bill. But at this point I turn you over to people who know more than I do.
  16. Is it an adult or a juvenile? Red-shouldered has breast and belly more or less the same, vent area lighter. Tail more dark than pale. In flight, pale or translucent crescents near and parallel to the wingtips. Soars with wings flat, wing outline doesn't have the bulge of Red-tails. When it's perched, you can often see neat rows of pale icicles or shark's teeth on a dark background on the secondaries--flashy white on black in adults, two shades of brown in juveniles. Don't forget to look in woods as well as fields. Good luck!
  17. Hi! there's only one kind of turkey in the U.S. and Canada, which is the Wild Turkey and its domestic descendants. (There's another species, the Ocellated Turkey, in the Yucatan Peninsula.)
  18. Sorry about my misleading use of "keeper", @IKLland and @Charlie Spencer. I just meant a good photo. I'm not thinking of deleting either of those. My question was more about sharing them.
  19. Thanks for giving your view, Charlie. I'm getting the idea that these shots aren't as exciting as I'd hoped.
