[ << | >> | ^^ ] Subject: Re: Early onset of 1st pre-basic molt in Short-billed Dowitcher From: Nicholas Block <sparrowhawk17(AT)yahoo.com> Date: 14 Sep 2003 8:53am Hello all, On a September 1 DFO field trip to Prewitt Reservoir in Colorado (I think it's in Washington County), we observed six juvenile Short-billed Dowitchers. Six SBDO at one spot in CO is rather unusual in itself, but I clearly remember one being in the early stages of its pre-basic molt. I believe it was only mantle feathers that had been replaced, but I cannot remember exactly where on the mantle. In any case, it certainly appears that molt before the wintering grounds does occur on _hendersoni_ and _griseus_, just rarely. Don's point about _caurinus_ is interesting, though. Has anyone recorded molt during migration on this subspecies? Nick Block Fort Collins, CO sparrowhawk17(AT)yahoo.com __________________________________ Do you Yahoo!? Yahoo!

As Joe Morlan's photo quizzes have shown, the guesses can sometimes be spectacularly divergent. At least we can be confident this bird is a warbler. I guess this bird looks, to me, most like an aberrant Common Yellowthroat. Take away that neck-band thingy, and the olive auriculars, bright eyering, relatively stout bill, yellow throat and upper chest and dull lower chest/upper belly all fit. So does the back color. What about the tail? Yikes! The apparently yellowish tail base seems to extend across all retrices and should thus eliminate Am Redstart parentage. Com Yellowthroats can show quite a bit of yellow-green at the base of their tails. Not as bright yellow as it seems in this photo, but I wonder if that lemon yellow color is partly photographic artifact. Soooo, if I had to bet, I'd place my dollars on an aberrant Common Yellowthroat. Cheers Steven Mlodinow SGMlod(AT)aol.com ----DELETED text/html MIME SECTION----

[ << | >> | ^^ ] Subject: Possible Sharp-tailed Sandpiper From: Scott Spangenberg <scottspangenberg(AT)MINDSPRING.COM> Date: 15 Sep 2003 8:05pm On Friday September 5, Rich Frechette, Eric Masterson, Dan Fallon, and I travelled to South Beach in Chatham, Massachusetts. While we never found either the Curlew Sandpiper or any Stints, we saw essentially the same variety of shorebirds that other folks reported for South Beach. Most interesting, however, was a thick-necked, dumpy Calidris sandpiper with a bicolored bill and yellow legs whose profile looked nothing like any Pectoral Sandpiper we had ever seen before. This bird positively gave us fits, and I would like to have your feedback on what you think it is. Although I thought that it was probably Pectoral Sandpiper, there were a number of details about it what I saw that really bothered me, not the least of which was the shape of the bird. I spent most of my evenings over the last week studying my photos and comparing them to illustrations, photos, and descriptions of Pectoral, Sharp-tailed, and Cox's Sandpipers (not much available on the last one of course). My perception now is that Sharp-tailed is a much better fit than Pectoral, but I have no prior experience with Sharp-tailed, and this bird appears to be an adult. So I need some feedback from folks who have more experience with this species and differentiating it from Pectoral Sandpiper. I have posted some photos with captions at http://www.scottspangenberg.com/Birds/CalidrisSp01/ GENERAL IMPRESSIONS -Large size compared to Semipalmated Sandpiper and Semi-palmated Plover, same size as nearby Pectoral Sandpipers. -Yellow legs -Bicolored Bill -Neckless appearance while active as well as while inactive (In other words, this bird had the general characteristics of Pectoral, Sharp-tailed, or Cox's Sandpipers, but did not have the form of Pectoral Sandpiper, the most likely candidate at this site and time.) SPECIFIC DETAILS OF OBSERVATIONS **-The bird appeared thick-necked and hunched at all times. When the bird stretched forward to feed, there was only the slightest indentation at the back of the neck. (See photos on my web site.) Neckless appearance (perfect match with outline of Sharp-tailed illustration in Sibley) even when feeding. -White throat instead of merely a white chin as PESA exhibits. -Obvious necklace below the throat (described variously as a necklace or thin gorget, which is not mentioned for any PESA plumage. I found this on many photos of STSA obtained with a Google image search, and on no photos of PESA. -Cap contrasts strongly with lower parts of head. In a photo of the top of the birds head, this contrast goes all the way around the head. In other photos, there does not appear to be much contrast at the back of the head. The contains rufous/chestnut, but is not strikingly rufous/chestnut. I found what I read about the usefulness of these two points for species separation a little confusing unless they only apply to juvenile birds. **-Supercilium widens behind eye, and while not as bold as I would have expected for this to be a Sharp-tailed, is bolder than supercilium of any other PESA we saw, or any photos or illustrations that I have been able to find. - A buffy white eye ring that was obvious even when the bird was facing us obliquely. (I am somewhat confused about the significance of this observation. One of the things I read seemed to suggest that Pectoral does not have an obvious eye ring, but that doesn't seem to always be true in my experience. I certainly have been able to perceive eye rings on Pectoral Sandpipers before. Perhaps what is meant is an obvious and complete eye ring?) -A dark eye stripe in front (dark lores) and behind the eye, with obvious contrast between the eye stripe and the area immediately below it -Bicolored bill, with orange base of bill (although a couple time it looked olive) and the outer part was black. The bill curves down slightly. Our collective observation through the scopes was that the orange was limited to the base of the bill, but some of my photos seem to show that more than the base is lighter than the tip. -Scapular set is complete (not missing or whitish at either end), therefore the plumage is not juvenile. Heavy feather wear adds weight to the idea that this is an adult bird. There is some rufous on the scapular feathers, and some white or buffy-white edges as well instead of brown scapulars with plain buffy edges as I expect for Pectoral. -Feathers of upperparts in general have dark brown centers and buffy edges. **-Upper tail coverts have rufous edges instead of being dark brown all the way to the edge **-While the bird did not run around as much as any of the other shorebirds, it was nevertheless quite active while feeding, which made it difficult to judge tail shape. Fortunately, one of my photos caught the bird with a slightly raised tail, and lowered primaries and tertials. The retrices are quite sharply pointed, and the middle two are quite a bit longer than the adjacent feathers. In flight, there was no big flash of white on the sides of the tail. **-Streaking does not extend below carpal joint as one would expect with PESA, and appears to have much less streaking in the center of the breast than on the sides. This is most apparent from a 45 degree view. Seen straight on, the bird has very light streaking across a large part of the central breast, and heavy streaking is limited to the sides. The streaking on breast has a subtle but perceptible buffy/yellowish wash underneath. This was is more apparent in the photos than during our observation. **-Subtle gray chevron marks on underparts at the flanks, just below the edge of the wing, which appear to be fading rapidly. Further back, adjacent to the undertail coverts, there are dark arrow-shaped marks. These were not as readily apparent in the photos as through my scope, so I included some photos where I have cranked up the contrast to bring out these marks. I have never ever seen a Pectoral with these marks, but these marks are specifically described for Sharp-tailed Sandpiper, I have found them on every illustration of Sharp-tailed that I can get my hands on. -Long tarsus and short tibia on yellow legs without any green cast. The small areas of the fronts were black. Most of the time, the only part of the tibia that was visible was the joint with the tarsus, even when the bird was leaning forward and down. Our spotting scopes included 60mm Kowa, 60mm Bushnell, and 80mm Pentax scopes, with 20X and 20-60X eyepieces on the Pentax. I did the photography using a 6.3 megapixel Canon D60 with a 100-400mm image stabilized lens, which yields an effective magnification of just under 13X, and a 5 megapixel Canon G5 attached to a digiscoping eyepiece for my Pentax scope.

[ << | >> | ^^ ] Subject: Possible Sharp-tailed Sandpiper From: Tim Janzen <tjanzen(AT)COMCAST.NET> Date: 15 Sep 2003 10:35pm Dear Scott, I think that this is a juvenile Pectoral Sandpiper. In my opinion plumage features which would suggest that this bird is not a Sharp-tailed Sandpiper would include: 1. The crown doesn't seem to be quite rufous enough. The black streaks through the crown are relatively wide, which would be more typical of a Pectoral Sandpiper. 2. The breast pattern doesn't seem right for a Sharp-tailed Sandpiper. There is relatively prominent dark streaking coming all the way across the center of the breast, which would be typical of a Pectoral Sandpiper, but not consistent with a Sharp-tailed Sandpiper. There is also reasonably strong contrast between the lower margin of the breast band and the white belly, which would again be consistent with a Pectoral Sandpiper. There also doesn't seem to be as much rufous coloration in the breast band as one would expect for a Sharp-tailed Sandpiper. 3. The supercilium doesn't seem to be as conspicuously white or as wide as one would expect for a Sharp-tailed Sandpiper. 4. The eye-ring doesn't seem to be as white or as prominent as one would expect for a Sharp-tailed Sandpiper. 5. There seem to be some white streaks in the crown, suggesting a split supercilium, which would again suggest a Pectoral Sandpiper. Sincerely, Tim Janzen 12367 SE Ridgecrest Rd.

[ << | >> | ^^ ] Subject: Possible Sharp-tailed Sandpiper From: KACastelein and DJLauten <birdsong(AT)HARBORSIDE.COM> Date: 16 Sep 2003 10:04am Folks, When I first saw this bird, I actually reserved judgement because I wasn't quite sure what it was. I am not seeing on my screen a well defined cap, that has lots of rufous, and I don't even find the supercilium to be very prominent. I have no experience with adult fall Sharpies, all the ones we see here are juveniles. This is not a typical juvenile at all, which it seems everyone agrees with. I think Ken has some valid points, and I am still in the camp that I'd like to hear what other people think. I am open to changing my mind, but I am still leaning towards Pectoral. Dave Lauten
[ << | >> | ^^ ] Subject: Re: Possible Sharp-tailed Sandpiper From: Rich Hoyer <calliope(AT)THERIVER.COM> Date: 16 Sep 2003 9:15am Hi Birders, Now with much expert opinions in favor of Pectoral Sandpiper, I'm not above reconsidering my opinion (Lauten's response arrived 4 seconds before mine). I don't get a lot of shorebird experience here in AZ, and I've certainly never seen an adult Sharp-tail this late in the season. I'm not so sure the lack of chevrons on the underside can so easily be dismissed as I suggested. The only reference to this I can find in my limited library is Paulson's Shorebirds of the Pacific Northwest, which states that even worn individuals show these clearly. However, I'm confused that others say that the bird has no rufous in the crown and a buffy supercilium. It's always a problem when judging photos (especially on computers) but my iMac clearly shows a well-defined rufous cap and a white, flaring supercilium. The bill does look long, which favors Pectoral. (Didn't Julian mean to say long, not short?) How many of us here have seen adult Sharp-tailed Sandpipers in mid-September? Are there any Australians here who can chime in? Can the pattern of the scapulars tell us anything? I wouldn't place any importance on the birds posture or shape.

[ << | >> | ^^ ] Subject: Re: Possible Sharp-tailed Sandpiper From: Kenn Kaufman <kennk(AT)IX.NETCOM.COM> Date: 16 Sep 2003 9:19am I'm looking at these pix on a small laptop monitor, and won't have a chance to look at them on a good monitor for several days; but from what I can see here, I'm not ready to jump on the Pectoral bandwagon. At least some of the people who are immediately ruling out Sharp-tailed seem to be thinking only of juveniles, and of course the juv Sharp-tailed is a very different creature. But molting adult Sharp-taileds in late summer and fall can be very tricky. They can indeed lose most of the chevrons on the flanks while retaining most of the streaking or spotting on the chest. The relative lack of markings in the center of the lower chest on the Chatham bird, clearly visible in several of Scott's photos, seems interesting, and I think the I.D. of this bird should be pursued a little further. Would any of the experts from the U.K. or Europe care to weigh in on this? I know that molting adult Sharp-taileds have caused some headaches in Britain in the past. Kenn Kaufman Tucson, Arizona
[ << | >> | ^^ ] Subject: Re: Mystery Warbler from NJ From: Mike Patterson <celata(AT)pacifier.com> Date: 16 Sep 2003 10:24am You know my first reaction was: why isn't this a Common Yellowthroat? Aside from the uncharacteristically bright yellow in the tail, that is. I actually thought I was seeing rictal bristals, barely visible on right side of the bill (bird's right). So, I figured: let's be provacative.... But after this note, I downloaded the photo and made it really big. What I was calling rictal bristals was actually a digital halo. No rictal bristal on this bird that I can find. That eliminates a lot of warblers. But that's still a lot of yellow in the tail. Way more than I expect in a west coast hatch-year yellowthroat and I handle 20 or 30 a year.....

I am not seeing a distinct rufous cap, salmony wash across the breast, and there is too much streaking across the breast - features that hint that the bird is not a Sharp-tail. I'm curious to hear what others think.

The worn condtion and dull color of the wing coverts and scapulars indicate an adult. The amount of rufous and the grizzled streaking in the face are perfect for Sharp-tailed, and the manner of the breast streaking seems to eliminate Pectoral. It does seem a bit clean below, but that could easily be the result of post-breeding body molt, and even then, some streaks are visible on the flanks. Excellent photos sure help.

[ << | >> | ^^ ] Subject: Re: Possible Sharp-tailed Sandpiper From: Martin Reid <upupa(AT)AIRMAIL.NET> Date: 16 Sep 2003 9:05am I agree with Julian that this is an adult Pec Sand (a juv should show much fresher, brighter scap and covert fringes, and less-worn primaries.) I have noted that some Pecs have light streaking on the most-lateral lower flanks, and that from time to time these are quite visible, creating a "molting-STSA-like" effect. More importantly, there is no sign of any streaks/marks on the undertail coverts - some of which is visible in a couple of the images; adult STSA retains much of this utc streaking in Basic plumage, and I would expect to see at least some hint of it in a bird in this stage of plumage (mostly Alternate.) Finally, STSA tend to have a shorter, darker bill with less pale at the base - the bill on this bird looks typical of Pec. Sand, to me. The apparent unevenness of the pectoral streaking is unusual, but not unprecedented - I've seen a couple of birds like this at this time of year (and like Scott I gave them a lot of scrutiny!)

[ << | >> | ^^ ] Subject: Sharp-tailed Sand id. From: julian hough <jrhough1(AT)SNET.NET> Date: 16 Sep 2003 10:11am ----INCLUDING text/plain MIME SECTION---- To expand on some of my comments, given the responses on this bird. To me, Sharp-taileds have a dumpy jizz and a shorter, slightly decurved bill. The rufous cap looks set far forward on the head and accentuates the prominence of the somewhat flared super behind the eye. The eyering is prominent and all the above contributes to a characteristic look. The underparts are not what I would expect from a Sharp-tailed at this time of year, even for a moulting bird. The moult would make the underparts appear a lot messier (especially on the lower breast?) in life rather than the clean look shown by Scott's photos. The pattern on Scotts bird looks too neatly confined to the upperbreast. I think the pattern of the scapulars show more pointed centres than Pec (I'm at work so i'm going from memory).

I have posted some photos with captions at >http://www.scottspangenberg.com/Birds/CalidrisSp01/ It certainly is an interesting bird, and I can see why it is being considered as a Sharp-tail. Still, on a quick look, I'd have to go with Pectoral. The shape characters just point to a cold or otherwise fluffed individual, and not to Sharp-tail. In fact, none of the photographs show it in what I consider the rather characteristic "leaning forward" posture that Sharp-tails often adopt. It does not have much of a capped appearance, perhaps more than most Pectorals, but nothing near Sharp-tail, and it has no rufous in the cap. The eyestripe is cream, not white. The chest band is not buffy, and has a lot of streaking, as in Pectoral. The dark necklace on the chest looks to be an artifact of the extreme hunched posture. (If you look at img_0873, the neck ring is obvious, but if you go to the next one, img_0869, where the neck is stretched out just a bit, the ring turns into a diffuse dark spot.) The undertail coverts are unmarked, and the few faint dark flank marks look just right for Pectoral Sandpiper (as shown by every individual in my photographic collection for which I have sufficient detail). They do not look to me to be chevrons, but each feather seems to have a dark rachis. Kevin ***************************************************** Kevin J.

The bird is an adult Pectoral Sand. Adult Sharp-tails have basically the whole underparts scalloped, not a distinct pec band of streaks. The lack of a rufous cap and a short, somewhat slightly down-curved bill also eliminate Sharp-tailed. Hope this helps Scott sleep a little better...

The quality of the captures is not great - sorry! The bird was video-taped at Gambell in early June, 1999. I remember the bird caught my eye because it was with a "normal" looking Pectoral Sandpiper, and this individual was extremely bright in plumage, with lots of bright rufous edging, especially on the cheek and crown, had a fairly prominent supercilium, and had some buff wash on the breast. Hopefully you can see these features on these jpegs. Just shows how variable Pecs can be! http://home.comcast.net/~ghrosenberg/Pectoral_Sandpiper_1.jpg http://home.comcast.net/~ghrosenberg/Pectoral_Sandpiper_2.jpg http://home.comcast.net/~ghrosenberg/Pectoral_Sandpiper_3.jpg Gary Gary H.

I have seen a few birds which have had brighter faces and richer chestnut crowns, but still, these birds if seen well, fall short of the basic suite of characters to suggest a Sharp-tailed Sand. Based on some comments on this thread, I think that the lack of records in the US of adult Sharp-tailed Sandpipers is probably the handicapping feature while in Europe, it seems that generally most records involve a higher proportion of adults as opposed to juveniles.

In fact some captions seem to belong to photographs not in the book at all. (For examples see photographs 571-578, they are all wrong, although some seem to have a suitable caption.) In due course a correct set of captions will be published somewhere by someone, until then, have fun trying to identify the correct and the erroneous captions. And watch this space for info on where you can find the correction file. With the correct set of captions, the book will be very useful indeed. annika forsten annika.forsten(AT)fi.intrum.com tel: +358-(0)9-22911812 +358(0)50-5953779 mobile +358(0)9-22911889 fax
[ << | >> | ^^ ] Subject: Gull Book, revisited (fwd) From: Ian Paulsen <birdbooker(AT)ZIPCON.NET> Date: 18 Sep 2003 1:48pm HI: FYI -- Ian Paulsen Bainbridge Island, WA, USA A.K.A.: "Birdbooker" "Rallidae all the way!" ---------- Forwarded message ---------- Date: Thu, 18 Sep 2003 15:33:23 -0500 From: Anthony X. Hertzel <axhertzel(AT)sihope.com> To: tweeters(AT)u.washington.edu Subject: Gull Book, revisited After compiling five pages of errors in the new Olsen and Larsson gull book, I finally called the publisher to try and learn if A) they are aware of the problem, and B) what they plan on doing about it. It turns out that Princeton University Press was actually not directly involved in the production of the book but bought it from a second party whom they declined to identify (though I have my suspicions who this might be). Princeton is aware of most of the errors and decided just yesterday to recall the book. The man I spoke with was uncertain what the method would be for the recall or how people would be notified, but full refunds will be given. He was also uncertain if the book would be reissued with corrections but thought this likely. Unfortunately, if you've discovered errors in the book, at this point there isn't anyone in particular that you can contact. This may change but exactly how and when has yet to be decided. -- Anthony X. Hertzel -- axhertzel(AT)sihope.com

[ << | >> | ^^ ] Subject: Re: Gull Book, revisited From: Glenn A dEntremont <gdentremont(AT)JUNO.COM> Date: 18 Sep 2003 6:48pm To be fair to the author(s) and working in the printing industry for a few years, these errors could be in the production of the book; especially if produced in a non-English speaking country. The half-tones (pictures) are done separately from the prose and then reunited. It is amazing how this process can go wrong. If printing in a language not your own, how will the pressperson know if it does not make sense? Also, there is no way a press operator will know if the captions to half-tones are correct. Secondly, dealing with imports, it is obvious that some manufacturers abroad (countries?) do little, if any, QA (Quality Assurance). Our company is currently trying to salvage a customer from such a QA mess. Glenn > > Why not the authors ? They will surely be involved if a corrected > edition > is produced.

[ << | >> | ^^ ] Subject: Re + : Gull Book, revisited From: Michel Bertrand <bertrmi(AT)colba.net> Date: 19 Sep 2003 8:52am Glenn A dEntremont, answering my previous message has written : > To be fair to the author(s) I'm just adding that I was not wanting to be unfair with the author(s) and I apologize if my message has been understood as so. My goal was only practical. I had understood that some people were not knowing where to send their comments about the new Gull guide because there are copies coming both from Princeton University Press and Helm. I have also worked in edition and was only meaning that "normally" the author(s) are asked for their corrections when a revised edition is produced. So, as there are two publishers for that book, I was suggesting that the most effective way to send comments would be to send them to Klaus Malling Olsen, the author of the text. It could be a good idea to do it with copies to Princeton and Helm which will know, then, that the author have received such comments. Unfair ? Because it seems Princeton will recall the book, what I wish is to be able to purchase the corrected edition as soon as possible and I am very grateful to the authors for producing the guide I was waiting to go a step forward the Grant's guide. Be happy... MICHEL BERTRAND Sainte-Julie, Qc bertrmi(AT)colba.net

[ << | >> | ^^ ] Subject: Gull Book. Comment from Klaus-Malling Olsen From: Harry Lehto <hlehto(AT)OJ287.ASTRO.UTU.FI> Date: 19 Sep 2003 3:32pm Dear All, regarding the new Gull guide by Olsen and Larson. I suggest that you get in touch with the publishing houses with your suggestions. I have discussed this matter personally with Klaus-Malling and he asked me to convey the following message to the BIRDWG01-list (see below). Please note that my intention is to keep this email as a single one-way message, but even as such hope that it will clarify the matter a bit. Regards Harry J Lehto hlehto(AT)utu.fi ======================================================= Klaus says: "Having just received the photoes for Gulls back from the editor, I am currently going through the photoes, published in the Gulls of Europe, Asia and North America . Indeed, there are a number of mistakes, where photoes have been switched off, and the "running order" have been disturbed, most serious in Heuglin's Gull and Herring Gulls, but also concerning some plate texts. Unfortunetaly, as soon as one photo have been wrongly placed, it affects the whole section. Sharp-eyed readers will find number of such inconsequences, as I did when comparing the photoes to the captions. The maps, too, hold a number of wrong colours, disturbing the impression. It is sad, but readers should be aware, that neither a second correcture nor a blue print, despite being promised by the editor, ever reached the authors. By July, I had expected a second correcture to arrive. What I received was the completed book! The original distribution maps was less colurfull, but more precise - the new ones, again, were never seen and accepted by the author. Readers should also be aware, that the author were mailed the colour seperations only (for acceptance). The author NEVER received a version of the photoes and the photo captions combined! It was most frustrating to see, that the book itself contained too many errors, which easily could have been found, if the editor has cared about mailing the final manuscript to the author, not just one correcture and a set of uncommented colour seperations" Klaus Malling Olsen
