The very ragged inner edges to the black tail band would make it difficult for me to call this bird Common Gull L. canus . On Mew/Short-billed Gull L. brachy... at this apparent age I'd expect to see entirely dark tail feathers. (West Coast observers may wish to disagree.) Instead, I see pale tale bases to the upper tail feathers. In the first photo, the shape of the bill looks passable for Common/Mew, but in the second photograph, it doesn't. I'd find it hard to make any judgments on the color and color tone of the bird from photographs we have. In short, I definitely think one cannot eliminate RBGU delawarensis. ----- Original Message ----- From: "Bill Rudden" <bilrudn(AT)YAHOO.COM> To: <BIRDWG01(AT)LISTSERV.ARIZONA.EDU> Sent: Saturday, December 12, 2009 4:24 PM Subject: [BIRDWG01] L. canus candidate Mississippi R.

[ << | >> | ^^ ] Subject: Re: An Interesting Pipit in Chicago (Water Pipit?) From: "French, Paul" <Paul.French(AT)RSPB.ORG.UK> Date: 14 Dec 2009 3:33am Greg, I really can't see a japonicus in your bird i'm afraid. If you turned the underparts of your bird buffy and the mantle was a touch more olive, it would be a bog standard rubescens wouldn't it? One of the main features for japonicus is the prominent black streaking underneath, clearly darker than the upperparts. On your bird, the steaking is the same colour or perhaps very slightly darker in colour than the upperparts. Check out the differences in these two birds showing the variation within japonicus, but still the streaking is blackish. A lightly streaked individual - http://orientalbirdimages.org/search.php?p=15&action=searchresult&Bird_I D=2094&Bird_Family_ID=&pagesize=1 A heavily streaked individual - http://orientalbirdimages.org/search.php?p=14&action=searchresult&Bird_I D=2094&Bird_Family_ID=&pagesize=1 Also, as others have pointed out, your bird lacks the distinctly brown tones above that japonicus should show, and the legs (while paler than classic rubescens) are no where near the flesh colour normally shown by japonicus. As for the yellow on the bill, well the bird on the Illonois thread underneath yours shows more yellow. And thats also a rubescens. The white tips to the median coverts are potentially interesting, but again, you only have to look at that other bird in the Illonois thread to see that its not impossible. A quick google search reveals that white tips to the median coverts are not that unusual. http://www.photomigrations.com/articles/0311600.htm http://www.lloydspitalnikphotos.com/d/5331-3/american_pipit_F5R7865 And here is a bird that actually looks similar to yours, but is still clearly a rubescens http://sdakotabirds.com/species_photos/photos/american_pipit_1.jpg In short, i can't see any features on your bird that would point towards a vagrant japonicus rather than a slightly odd rubescens. Paul French UK -----Original Message----- From: NBHC ID-FRONTIERS Frontiers of Field Identification [mailto:BIRDWG01(AT)LISTSERV.ARIZONA.EDU] On Behalf Of Greg Neise Sent: 13 December 2009 00:09 To: BIRDWG01(AT)LISTSERV.ARIZONA.EDU Subject: Re: [BIRDWG01] An Interesting Pipit in Chicago (Water Pipit?) A final note about the photographs. One of the inherent problems with the little ultrazoom cameras, like the FZ18 that I use, is that they are consumer products, and the image sensor just can't handle bright, high-contrast subjects as well as a DSLR. I had adjusted the exposure to what I felt was as close as I could get, but one thing has been nagging at me, and that is the bird's malar area. When I first saw this bird, my immediate reaction was "yellow-rumped warbler". The reason for that was the bird's overall gray tones, heavy streaking on the chest, and a heavy dark mark on the upper breast/malar/side of neck area and clean white throat. It really stood out, giving the impression of the glommed up streaking on the upper breast of a breeding Yellow-rumped Warbler. Of course, in the very next second, I realized it was a pipit...but the photos as I have them on the forum-even though I feel that they give the best overall impression of the bird-failed to exhibit that mark which first got my attention. The other thing about the photos I've noticed is that the bird's plumage seems reflective. The sun was directly behind me (at 1PM, when I found the bird), and low in the sky (being mid-December). If you look at the images I've attached to this email, you'll notice that in image _5646 the median coverts seem gray with rather broad pale gray fringes. But if you look at image _5643, where the bird has shifted slightly and is now at an angle to the sun, the median coverts appear as I saw them in the field: black centered with broad white fringes. The same goes for the upper breast/malar markings. In the two images that best show this, the bird is flat to the sun and the breast is blown out, and the dark markings washed out (_5646a). In image _5646, I've adjusted the exposure so that this appears more like it did in the field, but because of the limited amount of image data caused by the high contrast subject, the image "blocks up" a little, and renders the legs darker than they appeared in the field. What I saw, what I think the photographs depict, and why I think that this bird is japonicus, are: Lateral throat stripe thick and blocky, appearing spotted and extending to the rear of the auricular. Crisp blackish streaking on crown and mantle. White eye-ring Clean white underparts, with dark gray to blackish streaking, that almost looked spotted. Black-centered median coverts with bold white fringes. Greater coverts with well defined light gray-to-white fringes, forming distinct white wing bars. Whitish "moustache-stripe" wrapping around behind the auricular. Necklace of blocky, almost spotted, streaks defining a clean white throat. Pale lores. Lower mandible yellow nearly to the tip. Leg color dark yellow/pale brown.

[ << | >> | ^^ ] Subject: Re: L. canus candidate From: Peter Adriaens <p_adriaens(AT)YAHOO.COM> Date: 14 Dec 2009 4:20am ----INCLUDING text/plain MIME SECTION---- One important difference is the pattern of the underwing. The underwing is fairly white and unmarked, contrasting against dark secondaries, which is typical of Ring-billed gull. In canus and, especially, kamtschatsensis, the underwing is heavily marked with brown, and the secondaries do not contrast as much.

Herring Gull From: Dave DeReamus <becard(AT)RCN.COM> Date: 14 Dec 2009 12:33pm This is a multi-part message in MIME format. ----INCLUDING text/plain MIME SECTION---- Hi, I photographed a gull in Easton, PA on November 20th and would love to = know any opinions the gull experts might have on this one. First, I = must apologize for the poor quality of the photos, which were taken in = pretty poor conditions, but I believe that there might be enough detail = in them to promote a possible identification. I have not changed the = photos in any way other than to crop them down some. They are at: = http://picasaweb.google.com/becard57/LocalNotables2009#. When I first arrived and did a quick scan with binoculars, my first = impression when I came across this bird was Iceland Gull since it = appeared so pale, especially on the mantle. Getting my scope on it, it = was obvious that it wasn't an Iceland but looked more like a Herring = Gull (dark wingtips, stouter bill, larger size, etc.). The bill = appeared to be dark all the way to the base like most 1st-winter = Herrings. What was most striking as it sat there was the very pale and = barred mantle, which I've never seen on any 1st-winter Herring Gulls = before (Photos 1 through 4; for size comparison, an adult Ring-billed = Gull is behind the bird). The head was very pale with a dark smudge = around the eye. The breast was also very pale compared to the overall = tan or brown appearance of almost all of the young Herrings I see. The = greater coverts appeared paler than the rest of the wing with dark = center spots (best visible on Photo 2). Eventually, the bird took off and landed again for a brief time before = it left for the day. During that short circle, I managed to get some = flight photos of it. That was when I noticed that the wings, especially = the inner primaries, were also very pale (Photos 5, 6, and 9). There = was a noticeable dark secondary bar (Photo 9). The rump of the bird was = also very light with barring similar to the mantle but finer than that = (Photos 11 and 12). Those bars appeared to extend out onto the tail, = which had a dark terminal band. As poor luck would have it, a small = tree trunk covered the only photo I have of the spread tail. = Unfortunately, I was trying to get photos of it in flight and didn't get = to see as much detail as I would have had I been watching it with my = binoculars or my scope. The odds are that this is some odd-plumaged American Herring Gull, but = upon looking at the "Gulls of the Americas" book, I noticed that were = several similarities between this bird and a 1st-winter European = Herring.

From: =?ISO-8859-1?Q?Greg_Neise?= <gregneise(AT)ILBIRDS.COM> Date: 14 Dec 2009 3:28pm Hi Paul, One of the things I've learned in the last few days (and one of the reasons I love discussions like this) is that there seems to 100% overlap...a steady cline in all features...from japonicus to rubrescens. One thing that I have noticed, and one of the reasons I chose to document this bird as japonicus (that isn't really mentioned anywhere) is the face pattern as a whole. As I looked at many many photos, I noticed that japonicus tends to show a more distinct face pattern created by the combination of a heavier malar "blotch", whiter mustachial (sub-mustachial?) stripe that tends to be longer and partially encircles the auricular, whitish supercilium all of which tend to contrast more with the auricular. Rubescens (from what I have noticed) tends to have much more buffy tones, without any real sharp contrast, a shorter mustachial stripe and more concolorus supercilium. The overall effect when combined with the usually more contrasting (again with white versus buffy) wingbars of japonicus, and usually heavier streaking on the back gives a different impression. One of the first people to send me an email from Europe remarked at how on first glance, the Chicago bird's face pattern was reminiscent of a Redwing (the European thrush)...indeed, my first impression was reminiscent of Yellow-rumped Warbler. I've assembled [at IBF] pictures that I'm certain are correctly identified from a number of birding web sites and articles. I've interspersed a few shots of the Chicago bird as well for comparison. But, at the end of the day, my motive for documenting this bird is because no matter what it may be, it is certainly unusual, and I want to make sure that it finds it's way into the "knowledge base". I don't know about others, but exercises such as this tend to burn information into the brain that casual study just can't compete with.

Herring Gull From: Peter Adriaens <p_adriaens(AT)YAHOO.COM> Date: 15 Dec 2009 4:07am ----INCLUDING text/plain MIME SECTION---- Hi John, Bill birds like these are certainly not straightforward in any way (which is probably another reason why few answers were received), but I would not call them 'obvious European Herring Gulls'. For what it is worth, here is my (European) perspective on them: Gulls 1 and 3-6: The tail pattern strikes me as unusual. I am not used to seeing such dense dark barring (vermiculations) on the outer tail-feathers. In addition, most of the birds still appear to show hints of rather smooth underparts/hindneck (not coarsely streaked), barred vent and quite densely barred upper tail-coverts, all more suggestive of American HG. Gull 2 (http://www.zbirdtours.com/dbs_gull02.htm): Only one photograph, which is inconclusive. Strongly bicoloured bill in February is seen in only a minority of 1st-cycle European HG. Gull 7 (http://www.zbirdtours.com/dbs_gull7.htm): Two small photographs, which do not show a lot of detail. Still, rump and upper tail-coverts strike me as a bit densely marked and quite dull-coloured, as do the tail corners. Underparts (including lower breast) do not look coarsely streaked.

Browsing ALL of the recent photographs on this thread (putative European Herring Gulls), the images portray individuals that fall well within the variation one could expect from 'northern' Smithsonian Gull (smithsonianus), despite the fact that they are unusually pale. Overall, the bill shape and the clean headed-ness appearance, and the almost two-tone appearance with the underparts on some of the examples, leads me to believe that they are just variants. We have exactly the opposite problem in Britain, whereby the variation of both juvenile 'argenteus' and 'argentatus' Herring Gulls 'throws up' on a frequent basis individuals that exhibit a number of features (all dark tails, darker underparts, distinct covert barring) of North American Herring Gull; it is a very difficult job assessing the genuine article from the high frequency of 'lookalikes' and it does suggest that there may be birds breeding in the peripheral regions which share ancestral history.

Herring Gull From: Bruce Mactavish <bruce.mactavish1(AT)NF.SYMPATICO.CA> Date: 15 Dec 2009 8:30pm This is a multi-part message in MIME format. ----INCLUDING text/plain MIME SECTION---- I think John Puschock's Florida 1st winter Herring Gulls emphasize how little we know about the variations, and what could be unrecognized subspecies, of Herring Gull in North America. Field guides and overall impressions generated about 1st winter smithsonianus is a chocolate brown washed body, mostly dark tail etc etc. This is the way it is for most 1st winter Herring Gull in the northeast where the species is abundant. My impression of interior North America Herring Gulls is a different bird than that. My own experience with interior 1st winter Herring Gull is limited to a couple days one Nov at Niagara Falls, a few days in an October at Point Pelee, Ontario and a few days in late Sept 2009 at Red Deer, Alberta dump and various published photos here and there. In a nut shell many of the birds didn't look as dark as the typical fresh 1st winter in Newfoundland would look at the same time of year. A significant proportion were more barred on upper wing coverts, tertials, scapulars and under tail coverts, and with more streaked, paler heads, and more barring and marbling at base of tail feathers. How would such birds look after living on the beach under the Florida sun for a couple months? Perhaps the sun bleaching out of pale background brown washes would create an even greater contrast with the darker barring? Speculation is my middle name. The fairly extensive tail bands of the Florida birds probably tell the continent they originated from. On Oct 24, 2008 I found myself standing with a bag bread on a wharf in the fishing port of Galway, Ireland surrounded by 50 1st winter argenteus Herring Gulls. Not one of them resembled the Florida birds. They all had narrow tail bands contrasting with predominately white based tail feathers and rump, very pale heads, a brown and white checkered contrast of barring on the wing coverts and other upper parts. They looked more like miniature Great Black-backed Gulls than the dark chocolate young Herring Gulls of northeast North America. It reinforced the idea that the majority of European Herring Gulls are different from North American Herring Gulls (northeast and interior). But there are gray areas where the two 'species' overlap in features as we know them now. BTW. European Herring Gulls should be very rare in North America. They are not so very common in Iceland where Lesser Black-backed Gull is far more numerous. European Herring Gull has a relatively small footprint on planet earth.

Herring Gull From: Alvaro Jaramillo <chucao(AT)COASTSIDE.NET> Date: 18 Dec 2009 6:32pm This is a multi-part message in MIME format. ----INCLUDING text/plain MIME SECTION---- John et al. I was there when Alex spotted one of these Euro Herring Gulls at the Volusia Co landfill. I have photos of the thing but have no time right now to post them. Everything looks really good for something non-smithsonianus, except the tail was darker than is typical on Herring Gulls. I see a lot of the western smithsonianus, and can say that this Old World type Herring Gull we saw on that day is out of the norm for anything we see as smithsonianus in North America. But the conundrum is that the bird is not quite right for a European Herring either perhaps, and once I get photos up I can let experts on the European taxa decide if that is the case. But it makes me wonder if we are being misled by geography here, and perhaps a horrible thought is possible - that these "not quite right" gulls may include young Vega Gulls. This is horrible because we are only coming to grips with the identification of this creature here in North America south of Alaska, and the thought that there could be a low level of them all the way to the east coast by now is a scary thought for field identification -but a wonderful challenge as well. Martin Reid was the first to think that this was a possibility, and I thought he was nuts, maybe he still is nuts (cheers Martin :-)) but he may have been dead right about the possibility of Vega well away from the West Coast. Here are some examples: http://www.martinreid.com/Gull%20website/veguinx.html Also recall the adult Vega Gull (unless someone can identify it as something else) that was in the Daytona Shores area last winter: http://www.coastside.net/chucao/gulls/Florida%20Vega.htm So take all of this into consideration 1) Vega is far more common in Alaska than Slaty-backed and Black-tailed; yet south of there it is the taxon that has been detected the fewest times. That means it is likely going unnoticed in the south, and perhaps the east. 2) Slaty-backed and Black-tailed have made it all the way to the east coast on various occasions now, so no reason the Vega could not. 3) Some of these Texas - Florida birds are in terms of appearance outside of what is normal for smithsonianus, they suggest European Herring, but that is also a square peg. But for Vega they may be well within what is normal! So I do think we have to open our mind to the Vega possibility, even along the Atlantic Coast. Gull fans - here is the info on the upcoming NA Gull Conference. It promises to be a blast, and at a place that is being discovered as a gull watching Mecca - Florida's central coast. The opportunities for up close and personal gull study there are like nothing I have ever seen in North America. http://www.nbbd.com/fly/gulls/index.html See you there.

Herring Gull From: Alvaro Jaramillo <chucao(AT)COASTSIDE.NET> Date: 19 Dec 2009 8:25am This is a multi-part message in MIME format. ----INCLUDING text/plain MIME SECTION---- John et al. Yes, this topic is cleverly convenient with regards to what I will talk about at the gull fiesta in Florida. Picture me with pinky in mouth doing a Dr. Evil laugh. But with regards to your questions, I am not sure that size is good or bad for vega vs. smithsonianus. Smith is amazingly variable, I assume Vega as well. If there are reported size differences between the two, I would imagine that the sample sizes for smithsonianus are large, but are they for Vega? In other words, could it be sampling error. My impression is that Vega is smaller than smithsonianus on average, but I must admit that I had never given it serious thought or looked at tables with measurements. In terms of structure though Vega seems on average to be thinner billed and longer-winged based on photos...but of course with complete overlap with smithsonianus. Again looking at photos and also in conversation with various gull folks, it seems that first cycle vega often have a rather wide dark tail band which appears as if the tail was all dark. Again this is variable, but it appears to be much more common than in European Herrings A few thoughts about the Florida gulls that are worth thinking about I think. 1) they are so highly contrasting. The whites are very white, and the black on primaries really black. The contrast is something I do not see on smithsonianus, which tend to be brown and buff, rather than black and white. Could a hybrid combination of smithsonianus with something else give us this? Could a hybrid with white-winged, or back-crosses create a **more** contrasting look? I don't know, but it is counter-intuitive. So as far as hybrids go the more likely ones would be the two you mention smith x Euro Herring, smith x Lesser Black-back which could create something like this perhaps? 2) The narrow but distinct white crestcents on the tips of the primaries. This strikes me as very consistent on these birds, and again something that is not something that stands out on first cycle smithsonianus, more of a feature you see on Thayer's Gull, or at least is is more noticeable on that species. This may just be an effect of the high contrast, the really black primaries making the pale fringe stand out. Vega Gulls tend to show noticeable white fringes on primaries in first cycle. 3) There are some gulls in winter in California that approach the "ideal" Vega Gull look but upon close inspection show pale inner webs to the primaries and have a Thayer's like underwing pattern. I am at a loss to understand what these birds are. They may be some extreme Thayer's plumage that is highly contrasting (often first cycle Thayer's are very barred and contrasting on coverts, like European Herring and Vega), but these extreme birds also have noticeable whitish bases to the tail unlike what is seen on Thayer's. I have seen these things on a few occasions every winter for the last few years and have been left with big question marks about what they are. Could Thayer's be hybridizing with smithsonianus? God help us. It would be good to see what the underwings look like on these oddball Florida Gulls, if any are Thayer's like that would be problematic. I posted this bird once, but it is worth looking at again. Its the second bird, the first cycle one. Look at how well patterned those coverts are, the bird has rather pale underwings approaching Thayers. But one wing has a first cycle pattern, and the other wing more of a second cycle pattern!!!

This is horrible because we are only coming to grips with the identification of this creature here in North America south of Alaska, and the thought that there could be a low level of them all the way to the east coast by now is a scary thought for field identification -but a wonderful challenge as well. Martin Reid was the first to think that this was a possibility, and I thought he was nuts, maybe he still is nuts (cheers Martin :-)) but he may have been dead right about the possibility of Vega well away from the West Coast. <snip> Gull fans - here is the info on the upcoming NA Gull Conference. It promises to be a blast, and at a place that is being discovered as a gull watching Mecca - Florida's central coast. The opportunities for up close and personal gull study there are like nothing I have ever seen in North America. http://www.nbbd.com/fly/gulls/index.html See you there.
