Rock Martin

I've added { { cn } } tags to a couple of statements in Rock Martin which are lacking sources. As this is an FA, I thought I'd mention that here, in case anyone wants to find supporting references. SP-KP (talk) 18:38, 17 February 2012 (UTC)

The statement about the genus often being subsumed into Hirundo if obviously true (even the books I own differ on the genus) but since it's been challenged I've removed the statement since it would require a list of books to verify, not worth the effort. The second statement was, I think supported by the source a little further on, so I've repeated that. That claim could also be lost with no great damage if still queried Jimfbleak - talk to me? 07:23, 18 February 2012 (UTC)

Status update

Some activity then - we have two articles at FAC (Common Tern and Noisy Miner), and Stresemann's Bushcrow at GAN, and I have some enthusiasm for giving Jackdaw a shove across the GA line (still quite a few articles to trawl through on the talk page). Once Jackdaw is GA, it might be time to think about a collaboration...funny, we'll have 3 tern FAs and no gulls....Casliber (talk · contribs) 19:30, 17 February 2012 (UTC)

Agree with Jackdaw. Before I read this, I was thinking that Tern might be a good collaboration... Jimfbleak - talk to me? 07:20, 18 February 2012 (UTC)
Gawd, what is it with you and terns.. (clears throat) ...sure! :) Casliber (talk · contribs) 11:24, 18 February 2012 (UTC)
Why not gull? I few months ago I dragged it up to a C or low B class from a start, and it's a good article to recieve a concerted push to the big leagues, as well as being an important and well read article. Sabine's Sunbird talk 21:54, 19 February 2012 (UTC)

Sourcing common names

During the current capitalizationathon, Curtis Clark suggested that all common names of taxa should be sourced. This makes sense to mewe're supposed to source everything elseand for birds, we do have a source. What would people think of adding a footnote to every lead sentence so it would look like "The Short-tailed Longtail1 (Macrourus brevicaudatus) is a beyond-rare bird of southern Zembla..."

1Gill, F. and D. Donsker (Eds). 2012. IOC World Bird Names (v 2.11). [Accessed "Date"].

? Maybe this could be tried first with candidates for GA and FA, as our extra-special sourced articles that get feedback, and if it goes over well, maybe a bot could do it for the rest. JerryFriedman (Talk) 22:39, 20 February 2012 (UTC)

Rather than putting it on the first line, perhaps the to of the taxobox would be a better place? I've been doing that for a while. Sabine's Sunbird talk 21:55, 22 February 2012 (UTC)
I was just about to suggest that; many articles put it in the taxobox, eg. Common chimpanzee. ErikHaugen (talk | contribs) 22:01, 22 February 2012 (UTC)
Okay, I'm glad this is already being done, and the taxobox seems like a good place. Do we want this to be a project policy? (I must say "robust chimpanzee" was new to me.) JerryFriedman (Talk) 23:22, 22 February 2012 (UTC)
They would be sourced in the taxonomy and naming section. I generally do this already. All info in lead should be expanded upon in the body where the inline ref can go). Casliber (talk · contribs) 21:01, 23 February 2012 (UTC)
Strongly concur with Casliber. It is important information to cite, but this should be done in prose. People needs to stop putting unique information and sources in infoboxes, since all sorts of sites and applications that re-use WP content drop non-inline template cruft entirely (e.g. any floating <div>...</div>), and infoboxes are nothing but such templates. They're just bullet-point summaries of misc. factoids, not independent mini-articles. — SMcCandlish   Talk⇒ ɖ∘¿¤þ   Contrib. 06:17, 28 February 2012 (UTC)

Transitional Fossil peer-review

It is a very important subject, and I wish to take it to GA/FA status in the future. A large section of the article discusses Archaeopteryx and the origin of birds. Input from members of this wikiproject would be highly valued. --Harizotoh9 (talk) 00:22, 23 February 2012 (UTC)

Birds for identification (138)

  • Bird 1380 File:Phoebetria palpebrata - SE Tasmania.jpg | Some opinions on this too please. JJ Harrison (talk) 08:28, 5 February 2012 (UTC)
I suspect this is also a Sooty, but it's a young bird, so harder to tell. Natureguy1980 (talk) 09:17, 5 February 2012 (UTC)
Rohan Clarke tells me this is an immature Sooty Albatross, based on "some colour on the sulcus and some patchiness in the plumage", as well as "The bird is too brown-toned for a LMSA especially across the body and wings. LMSA are always much colder grey-toned. In all plumages they should also show a lovely pale steely grey back whereas your bird is quite dark brown. Some LMSA individuals can get paler than a typical adult LMSA with wear, especially juveniles but they never get darker. Your nice flight shots also show that the wings are too broad and good head profiles show that the bill is too robust and not 'pinched' mid-way along its length as you would expect for an LMSA." based on other shots from other individuals too. I'm therefore moving the image. JJ Harrison (talk) 20:35, 5 February 2012 (UTC)
Please note that after moving a file on Commons, it is usually a good idea to delete the redirect from a file name with the wrong name to the new file with the good name. Snowman (talk) 20:27, 26 February 2012 (UTC)
Sooty Albatross is now at File:Phoebetria fusca immature - SE Tasmania.jpg. Snowman (talk) 20:27, 26 February 2012 (UTC)
Please note that before deleting a redirect on Commons, it is usually a good idea to fix any references to the file. JJ Harrison (talk) 10:36, 2 March 2012 (UTC)
I think that a useless redirect is a redirect from a file name of the wrong species going to the correctly named file. Snowman (talk) 10:58, 2 March 2012 (UTC)
It's a juvenile. Adults of both sexes have uniform grey upperparts. Other pointers are the rufous fringes to the feathers on the visible part of the wing and the coarse, fringed barring on the underparts. Females have neater and greyer barring Jimfbleak - talk to me? 13:16, 7 February 2012 (UTC)

Commons or en Wiki does that sometimes. I did not see the image today until I clicked on the link to the image, which I found where the image is usually seen. If you are viewing from within Commons (ie have the Commons icon in the upper left hand corner instead of the "Wiki globe"), then the image is seen normally. If this does not work, then try again later. Snowman (talk) 11:35, 28 February 2012 (UTC)

Vancouver

It looks as if I'll be going to Vancouver in the summer for a family event. Sibley should be OK for bird ID, can anyone recommend a site guide to this area (I was rather hoping in would be in the World Cities birding guide, but it isn't...) Jimfbleak - talk to me? 06:31, 24 February 2012 (UTC)

Try these areas: Iona Island (British Columbia), Wreck Beach, George C. Reifel Migratory Bird Sanctuary. They are all in the south of Vancouver but not far. Dger (talk) 22:36, 24 February 2012 (UTC)
Thanks for that. I've just come back from seeing Common Yellowthroat and Lesser Scaup in South Wales, there was also a Bonaparte's Gull in Cardiff, at this rate I'll have a decent 2012 NAm year list before I get there (: Jimfbleak - talk to me? 16:45, 25 February 2012 (UTC)

Bird anatomy - circulation

I have replied over there. Snowman (talk) 12:05, 27 February 2012 (UTC)

Problem with redirects:

It doesn't seem to matter that much. There is not even a stub as far as I could determine. In any case, prout IOC = White-breasted Ground Dove. Other english common names that have been in the past commonly used for this bird (Gallicolumba jobiensis), are Purple Ground-Dove, Purple Ground-dove, White-bibbed Ground-Dove, White-bibbed Ground-dove.Steve Pryor (talk) 14:50, 1 March 2012 (UTC)
I created a stub and fixed the redirects. Dger (talk) 17:55, 1 March 2012 (UTC)
New stub is at Gallicolumba jobiensis. Snowman (talk) 19:25, 1 March 2012 (UTC)
Sorry had a typo when I did the move. The page listing is at is White-beasted Ground Dove (I missed the r in breasted). Should be OK once the page is fixed. Was going to let y'all know in the next set of locked page changes,, didn't think anyone would care until then......Pretty quick Snowmaradio!....Pvmoutside (talk) 20:52, 1 March 2012 (UTC)
Please do not leave articles and redirects in a bad mess like this. It seems that you left one article orphaned with the wrong name and virtually inaccessible. This mess with page names is denying readers access to this page (this dove article got 253 views in February 2012). I have changed the new stub that User Dger kindly made back to a redirect. Look at all the inconvenience this has caused. Snowman (talk) 21:06, 1 March 2012 (UTC)
An administrator kindly deleted a page and I moved the dove to the correct page. I have also fixed a number of redirects. Snowman (talk) 21:08, 1 March 2012 (UTC)

  • Symposiachus manadensis

......Pvmoutside (talk) 23:47, 2 March 2012 (UTC)

Delete the erroneous spelling. This is a mistake in orthography, not an alternative spelling! This is one of the ways in which so much of the mistaken information has crept into the grey literature of ornithology. To keep the mistaken spelling around is to add a certain valence to it. Out, damn'd spot!Steve Pryor (talk) 10:20, 3 March 2012 (UTC)

White-necked Rockfowl

Hello, in White-necked Rockfowl#Reproduction it's written: "The White-necked Rockfowl has two breeding seasons throughout the year" then "Guinean birds breed from July to January, while those in Sierra Leone breed from November to February and from April to October". Does it mean that Guinean Rockfowl have only one breeding season, or that they have two clutches in six months? Totodu74 (talk) 16:02, 2 March 2012 (UTC)

Good question that someone with the cited Fry-African-birds reference needs to answer. I would however imagine that it is not two clutches but two peaks in breeding (before and after the rains) - a pattern that is also found in the Asian Monsoon zone. Shyamal (talk) 15:08, 4 March 2012 (UTC)
Thanks, it makes sense indeed. (I still wait for a sure answer from the reference anyway) Totodu74 (talk) 14:23, 7 March 2012 (UTC)

Bird dimensions

An IP, who seems to be interested in bird sizes, has been editing articles about large birds; see these edits. I am not certain about these bird sizes, because different sources might say different things. Snowman (talk) 19:44, 2 March 2012 (UTC)

This IP and similar ones beginning with 86.46 (originating in Dublin, Ireland) have been making these sorts of edits before. The edits appear to be constructive but if you try to verify them the references don't exist or are too vague to even find. Usually, several editors waste a lot of time reverting the edits. Here we go again. Dger (talk) 21:16, 2 March 2012 (UTC)
Yup. I'm reverting on sight now. I see no evidence that he's editing in good faith. I know that other people on WP:BIRDS have been too... but speaking of reverting, could anyone reverting him please make sure to revert *past* any intervening bot edits to the last non-86.4* edit? They interspace themselves with his edits sometimes. Just something I noticed the last time I reverted him. --Kurt Shaped Box (talk) 07:52, 3 March 2012 (UTC)
Any edit that includes oiseaux-birds.com as a citation should, in most cases at least, be reverted. For this reason. He also has a tendency to use citations that scores low at WP:RS, e.g. blogs. Somewhat related, I just discovered large parts of Ferguson-Lees and Christie's Raptors of the World are available on google books. Just search for its name at books.google.com. The typical measurements (wingspan, total length) are at the plates; other more detailed measurements are the end of the main species text. Use the search on the lower left of the book's page to find the sections fast (in general, specific name is the most effecient, e.g. pelagicus for Steller's Sea Eagle). Handbook of the Birds of the World, quoted in several eagle owls, provides the following total lengths and weights: Great Horned (male 51 cm and 680-1450 g, female 60 cm and 1000-2500 g), Magellanic Horned (c.45 cm), Eurasian (60-75 cm, male 1500-2800 g, female 1750-4200 g), Rock (56 cm, c.1100 g), Pharaoh (46-50 cm, male c.1900 g, female c. 2300 g), Cape (48-58 cm, male 900-1400 g, female 1200-1800 g), Spotted (c.45 cm, male 490-620 g, female 640-850 g), Greyish (c.43 cm, c.500 g), Fraser's (39-45 cm, male c.575 g, female 685-815 g), Usambara (48 cm, 770-875 g), Forest (51-64 cm), Barred (40-46 cm), Shelley's (c.61 cm, one male 1257 g), Verreaux's (60-65 cm, male 1615-1960 g, female 2475-3115 g), Dusky (48-53 cm), Akun (40-46 cm, male 485-535 g, female 525-610 g), Philippine (40 cm), Blackiston's (60-72 cm). We're not exactly innocent in using questionable citations either: In the Eurasian Eagle Owl, we used oiseaux-birds.com, and the upper weight measurements were based on this blog, itself a questionable source, but even more so when the relevant text is "Boo’s [some captive bird] carer told us that she weighs about 10 pounds (4.5 kg). That’s typical for females." She weights "about" and that's "typical". Really!? I removed that citation and changed it to a combination of owlpages.com and Handbook of the Birds of the World. –212.10.93.66 (talk) 16:58, 3 March 2012 (UTC)
It's the same principle as the "diet of frogs", but with the added tweak of pseudo-references; either not RS, or RS (like HBW) but no page numbers, so you could waste a lot of time trying to check, assuming that you had access. I revert on sight too, and I've blocked occasionally, but this appears to be a dynamic ISP (not a proxy, or the bot would block). Jimfbleak - talk to me? 19:55, 3 March 2012 (UTC)
I wonder if it is worth making a page "List of the one hundred largest birds" (possibly partitioned into family or order sections) with referenced dimensions, and this can help us to decide when to revert. Snowman (talk) 22:15, 4 March 2012 (UTC)
If you're going to do anything that has the effect of ranking the great eagles in order of size, expect a firestorm (or perhaps a string of gradual passive-aggressive figure-changing from uncommunicative IPs). Ever notice how people seem to like to big up their favourite eagle, whilst diminishing the others? :) --Kurt Shaped Box (talk) 23:43, 4 March 2012 (UTC)

Birds for identification (139)

It is an alba personata, an adult male. It is still mostly in the winter plumage but it is starting to transition (the only difference between the two personata plumages in the adult male being that it has a whitish moustachial, and a white throat in winter, and the breeding plumaged male loses all of that throat white and the throat becomes totally black.Steve Pryor (talk) 17:27, 27 February 2012 (UTC)
I thought that it looked like that subspecies, but its location does not correspond to the range on File:MotacillaAlbaDistribution.svg, which is shown on the en Wiki article. Snowman (talk) 19:04, 27 February 2012 (UTC)
I would rather trust my references, including "Pipits & Wagtails of Europe, Asia and North America", Per Alstrom and Krister Mild.Steve Pryor (talk) 21:46, 27 February 2012 (UTC)
Would agree with M. a. personata. That map in any case says nothing about wintering ranges. Shyamal (talk) 02:52, 28 February 2012 (UTC)

I'll make the call on this one. "In Africa", well, I will take it on faith though it appears strange that he only shot one bird shot in his "safari". It is included in a mixed-bag set obviously captive animals somewhere! Nonetheless, the photo already on the species page is an adult male nominate erythrocephalus erythrocephalus.

Shown on en Wiki species page. Is the one in the infobox of the species page a male? Snowman (talk) 18:20, 28 February 2012 (UTC)
Yes, I already commented above. To reiterate, the one on the species page infobox is an adult male nominate race erythrocephalus erythrocephalus.

Impossible to say, according to my sources. Adult males lack streaking on the mantle, which this bird has. And females are said to "look more and more like adult males as they age". In my opinion, this bird is not sexable. Natureguy1980 (talk) 20:50, 29 February 2012 (UTC)

Oh dear.....

Crown (anatomy) is ...erm...interesting. Needs an overhaul. Anyone with some bird anatomy books - could be a DYK maybe. Am posting this as am tidying up a couple of other things before hitting the hay....Casliber (talk · contribs) 14:00, 4 March 2012 (UTC)

<giggles> I'm not sure making the article bird-specific would be justified though. -- OBSIDIANSOUL 14:13, 4 March 2012 (UTC)
The current "crown (anatomy)" article seems to be to bias towards bird anatomy. Can a separate article on "Crown (bird anatomy)" be justified? Do all birds have a crown, not just the ones with a crown that stands out because of contrasting feather colours? Do all mammals have a crown too, at least the ones with roundish heads? I am not sure if reptiles and insects have a crown or not, and I think that most of them do not have round heads. A modified "Crown (anatomy)" article, might be along the same lines as the Temple (anatomy) or Occiput article. According the the wiki article on occiput, insects have an occiput. Snowman (talk) 14:41, 4 March 2012 (UTC)
Yes, all birds have crowns, just as they all have eyes and feet. Natureguy1980 (talk) 19:45, 4 March 2012 (UTC)
I could tell you about this one gull that was part of my local flock years ago that didn't. Have feet, that is. (S)he would be either sitting or flying. --Kurt Shaped Box (talk) 20:58, 4 March 2012 (UTC)
Touché. :-) Natureguy1980 (talk) 02:33, 5 March 2012 (UTC)
Heh. But seriously - I've been thinking about this and I've remembered about all the feral pigeons I've seen that have feet and toes in various states of rotting, falling apart and dropping off. Does anyone know what causes this? Don't know if it's something more prevalent amongst feral pigeons than other birds, or if it's just that there are lots of feral pigeons around and some of them come quite close and thus, I notice that some of them seem to be suffering from something like dry gangrene. --Kurt Shaped Box (talk) 16:18, 5 March 2012 (UTC)
Guesses: could be frostbite, could be strangulation due to debris/droppings adherent to toes, could be trauma caused bird traps at various stop-off areas during migrations), could be trauma due to bites from meat-eating animals or territorial fights. I expect any of these could lead to infection including gangrene. Snowman (talk)
Roosting/breeding/loitering amongst the rotting carcasses of their deceased brethren probably isn't helpful either. If that actually really happens. Or is that just anti-street-pigeon propaganda (i.e. "look! they're so stupid/dirty/immoral that they even associate with corpses - how can you say that these things deserve to live?" - well, that would *seem* to be the unspoken subtext)? --Kurt Shaped Box (talk) 20:56, 5 March 2012 (UTC)
Agree, unless there is much more than I would expect on the crown of the head, a general animal article should do. I would think that there would need to be some distinction made between the actual crown of the head, presumably present in most terrestrial vertebrates, and the appearance of a crown as in the (unnecessary) listed species. Jimfbleak - talk to me? 16:03, 4 March 2012 (UTC)
In insects this or something near it is called the Vertex_(anatomy), maybe a candidate for a merger. JerryFriedman (Talk) 19:31, 4 March 2012 (UTC)
Top of head (biology)? :) --Kurt Shaped Box (talk) 20:58, 4 March 2012 (UTC)
Added a tighter (bird related) definition with ref. I think when used in common names it often has a somewhat looser meaning, dependent on plumage colouration. Maias (talk) 04:02, 5 March 2012 (UTC)
If a separate crown article for birds is justified it would be because the term is used so widely in bird identification. I guess an alternative would be to have it in Wiktionary instead. Maias (talk) 04:41, 5 March 2012 (UTC)
  • I think that in the study of human anatomy the term "crown" is not used much or it has no strict definition; however, Calvaria (skull), "skullcap", "skull cap", or the "roof of the cranial cavity" are used. I have been looking at a 996 page book on human anatomy, but so far I have only found the term crown with reference to teeth. Perhaps, something will turn up in other books or dictionaries. Snowman (talk) 10:41, 5 March 2012 (UTC)
  • From the OED: there are many meanings mainly about roundish things on the top of something. It also says that the crown is the top of the head and alternatively the whole head. One specific anatomical use in the OED is for "The eminence on the head of a whale, in which the blow-holes are situated." It has several meaning in plant anatomy also. Snowman (talk) 10:57, 5 March 2012 (UTC)
I think there is little scope for a general anatomical article on "crown" beyond a brief definition or disambiguation. With regard to the bird crown, there would be scope for a section in a article on "bird topography" (as well as bird anatomy - which is what the phrase redirects to, though it is not properly covered there, despite the excellent illustration). Such a section should focus on the visual aspect - skin or feather texture and colouration, including any crest - and its function in identification, whether by humans or conspecifics. There is really not much to say about "crown" as the top part of the skull; it can easily be covered in the anatomy article. Maias (talk) 11:18, 5 March 2012 (UTC)
With a heading "Crown (anatomy)" it is not primarily a bird article. Shed is also an article about different structures of sheds, so "Crown" article might be like the article on "Shed". Snowman (talk) 11:35, 5 March 2012 (UTC)
Should the scope of the article be reduced by re-naming it "Crown (vertebrate anatomy)", so that plant anatomy is not included or should plant anatomy be included? Should it be converted into a SIA? Snowman (talk) 11:42, 5 March 2012 (UTC)
Well, I am not sure that it fits a set index easily, though some sort of dab would be useful. I want to emphasise, however, that for birds "crown" is largely an ID term. It is not about the 3D upper part of the skull but about the curved 2D visual surface. In this sense the term is used in a different way to that usually applying to most other animals. Maias (talk) 13:07, 5 March 2012 (UTC)
In my opinion, a mass of feathers on the top of a bird's head is not a 2D structure. Snowman (talk) 13:14, 5 March 2012 (UTC)
Aside from crown also being an anatomical designation in plants, the crown of the teeth are also technically anatomical which confuses the scope even more.-- OBSIDIANSOUL 21:06, 5 March 2012 (UTC)
Why not just set up a glossary for strictly bird anatomical parts, and then use that as a backstop for cross-linking from bird articles as necessary? Dictionaries of ornithology do exist. I use this one: http://www.amazon.com/Ornithologists-Dictionary-Johannes-Erritzoe/dp/8496553434Steve Pryor (talk) 08:52, 6 March 2012 (UTC)
OK, let's sort out the confusion. There may or may not be justification for an article on the anatomical feature. I don't think that article exists, whether it should is another matter. The article under discussion is effectively about the plumage feature, and consists mainly of a list of birds with crown in the name. It makes as much sense as having an article toe (bird) with Short-toed Eagle, Short-toed Treecreeper, Long-toed Stint etc. Proposal 1 convert this article to a redirect to feather, add a sentence there. Separate Proposal 2 consider whether there is a need for an article on the anatomical feature, either for birds or all vertebrates; if so, write a stub Jimfbleak - talk to me? 09:59, 6 March 2012 (UTC)
I like Steve's idea of the glossary — perhaps something along the line of the glossary of entomology terms. That gets rid of a bunch of quasi-related stub articles, while putting things into an easily findable place for both editors and readers. MeegsC | Talk 16:08, 8 March 2012 (UTC)
Yes, a glossary might be the answer. Another example is Glossary of botanical terms. Maias (talk) 10:23, 10 March 2012 (UTC)
