Red warbler

This article is about a cute little bird from Central America - so far birds from outside anglophone areas are a tad underrepresented, so here goes. It is comprehensive (as far as we know) and prose is ok (I think). In any case, we'll try and fix any issues pronto. Have at it. Cas Liber (talk · contribs) 07:06, 29 April 2018 (UTC)[reply]

Comments from FunkMonk

• Sure looks cute, will review soon. FunkMonk (talk) 23:16, 30 April 2018 (UTC)[reply]
• We don't have much diversity in images for this bird, but I wonder if this photo[2] could be added? It shows the grey patch of C. r. melanauris better than the taxobox image, and is sharper, so it isn't wholly redundant.

I have replaced the taxobox image with it. Agree it is better Cas Liber (talk · contribs) 01:45, 1 May 2018 (UTC)[reply]

• I wonder why the name of the supposedly nominate subspecies ruber is not spelled the same way as the specific name (rubra)?

A hangover from when it was in its old genus, which was masculine. Changed now (IOC has subspecific rubra as well) Cas Liber (talk · contribs) 01:42, 1 May 2018 (UTC)[reply]

Good, seems you missed the taxobox image caption. FunkMonk (talk) 16:45, 1 May 2018 (UTC)[reply]

• What's the meaning of the other subspecies names?

melanauris means with dark ears and is half greek half latin. Will get pages and add later added now. Cas Liber (talk · contribs) 01:42, 1 May 2018 (UTC)[reply]

added info on rowleyi MeegsC (talk) 21:05, 1 May 2018 (UTC)[reply]

• "soon after its independence" add date for context?

Added date of independence MeegsC (talk) 16:59, 1 May 2018 (UTC)[reply]

• "which was assigned to the genus Setophaga" You could write the full binomial here, otherwise the specific name isn't mentioned until far down.

Done. MeegsC (talk) 18:17, 1 May 2018 (UTC)[reply]

• "and pink-headed warblers" Link at first mention.

Move wikilink to first mention. MeegsC (talk) 17:03, 1 May 2018 (UTC)[reply]

• "and their common ancestor diverged from a lineage" When?

No idea; the study doesn't give a date, or even a date range. MeegsC (talk) 17:51, 1 May 2018 (UTC)[reply]

• Where the subspecies originally described as species? If so, should be mentioned, also when they were lumped.

C. r. melanauris and C. r. rowleyi were described as subspecies, so weren't lumped. Clarified in article. MeegsC (talk) 18:29, 1 May 2018 (UTC)[reply]

• "Its legs are flesh-colored, and its flesh-colored bill" What exactly is meant by "flesh coloured"? Can a more precise description be found?

changed former to red-brown and later to pinkish-gray, with ref.

• You give scientific names for some other species mentioned under description, but nowhere else. Should be consistent.

Removed scientific names for other species; no need for them here, particularly as species are wikilinked. I've left the names that would apply if various subspecies were to be split. MeegsC (talk) 17:57, 1 May 2018 (UTC)[reply]

• "its slightly darker wings and tail" Darker red? They look grey or brown in photos, so could be more specific.

See I would assume that "slightly darker" meant same colour. Anyway, I found another ref that describes it as "dusky" Cas Liber (talk · contribs) 00:49, 5 May 2018 (UTC)[reply]

• "The feathers of this species contain alkaloids" Seems this would be relevant under behaviour? Is this to protect from predators? In which case, not only humans would avoid eating them...

the info is pretty redimentary. I dug around and found some more details, but any other assumptions would be OR. Will see if any conclusions or covering statements can be found. Cas Liber (talk · contribs) 01:58, 5 May 2018 (UTC)[reply]

• "the red warbler has three disjunct populations" Do these correspond to the subspecies? if so, could be stated.

Well, they are indicated as such in the taxonomy section, but we can repeat them lower down in the habitat and distribution section too if you think we should. Or say it there instead. MeegsC (talk) 07:06, 2 May 2018 (UTC)[reply]

I think you could add something like "corresponding to the three subspecies" for clarity, I imagined it was the case, but it might be harder for people skimming the article. FunkMonk (talk) 13:37, 2 May 2018 (UTC)[reply]

added Cas Liber (talk · contribs) 02:48, 4 May 2018 (UTC)[reply]

• Support - looks good to me now, as has been pointed out below also, could be nice to add anything on predators if possible. FunkMonk (talk) 00:48, 7 May 2018 (UTC)[reply]

Comments from JM

• Could you check the Escalante and Daly citation?

added title

• I'd love some more pictures, but if that's all we have, that'll have to do!

Do you think this one is worth adding? It does show some habitat, and has an appropriate license.

I do- I like it! Josh Milburn (talk) 08:10, 13 May 2018 (UTC)[reply]

uploaded and added now Cas Liber (talk · contribs) 13:47, 14 May 2018 (UTC)[reply]

• "the red and pink-headed warblers were each others' closest relative" Why past tense?

Changed to present tense.

• Are "trills" and "warbles" jargon, I wonder?

the first is a high pitched vibration call and the second a series of soft notes. I had just known them but then again I am a birdwatcher. We only have a general article on birdcalls (Bird vocalization - already linked just before) and wiktionary isn't much help either. Not sure the best way to go about it for laypeople Cas Liber (talk · contribs) 09:58, 9 May 2018 (UTC)[reply]

I'm probably worrying about nothing. I know what they mean, I was just thinking that others may not. Josh Milburn (talk) 08:10, 13 May 2018 (UTC)[reply]

• "It is fairly common to common in the interior and on adjacent slopes" Maybe I'm being obtuse, but I'm struggling to follow this.

"fairly common" and "common" are used as distinct descriptors, with the former being less common than "common" but commoner than "uncommon". I can't see the source page though.. Cas Liber (talk · contribs) 09:47, 9 May 2018 (UTC)[reply]

I was struggling to understand what "the interior and adjacent slopes" meant. Interior of what? Adjacent to what? Josh Milburn (talk) 08:10, 13 May 2018 (UTC)[reply]

@J Milburn: I've tried to clarify a bit; is it clearer now? MeegsC (talk) 22:20, 22 May 2018 (UTC)[reply]

• "hover gleans" sounds like jargon

Modified slightly; is that better?

Yes, much better. Josh Milburn (talk) 08:10, 13 May 2018 (UTC)[reply]

• I wonder if we have any information about human interactions/uses or the bird's appearances in human culture?

nothing found to date Cas Liber (talk · contribs) 09:59, 9 May 2018 (UTC)[reply]

• There's no mention of lifespan - I assume there's no information available?

That's correct; lifespan is unknown.

• There's some mention of predators, mixed flocks, and competitors with which it feeds; I wonder if we could be more specific about these things? I'd certainly be interested to know!

added a bit (see below for specifics) Cas Liber (talk · contribs) 04:13, 10 May 2018 (UTC)[reply]

That's about it! Looks very good to me. Josh Milburn (talk) 09:04, 6 May 2018 (UTC)[reply]

Leaning support. A little light on some details, but I am happy to take your word for it that this reflects the literature. I do wonder whether there might be more out there in Spanish (or other local languages), but appreciate that this is a tricky question! Josh Milburn (talk) 16:44, 19 May 2018 (UTC)[reply]

Actually, my Spanish is pretty good. And I've looked for references in that language too! MeegsC (talk) 21:59, 19 May 2018 (UTC)[reply]

That's good; thanks for the clarification! Josh Milburn (talk) 06:26, 20 May 2018 (UTC)[reply]

Comments from Jens Lallensack

Happy to review this article. Its reads extremely well, great job with the prose. It could be more comprehensive, however. Comments below:

• Why was File:Ergaticus ruber.jpg removed? I think that one is still a valuable addition.

In two minds about this. I replaced the taxobox image with a more in-focus one. If I re-add this one, what am I implying it has that other photos don't have? Cas Liber (talk · contribs) 20:31, 7 May 2018 (UTC)[reply]

I thought it shows parts of the plumage not visible on the other images, including the back and the upper side of wings and tail. But the decision is yours, of course.

good point. readded Cas Liber (talk · contribs) 00:46, 10 May 2018 (UTC)[reply]

the latter - done Cas Liber (talk · contribs) 20:36, 7 May 2018 (UTC)[reply]

• the scarlet tanager and summer tanager have similar mostly-red plumage but are larger with thick conical bills – You describe the bill shape of similar species, but not for the red warbler itself. Should be added to the description if possible.

added Cas Liber (talk · contribs) 21:09, 7 May 2018 (UTC)[reply]

• There is no information on how males and females differ from each other in both color and size. If they are identical, this needs to be mentioned also.

done Cas Liber (talk · contribs) 21:09, 7 May 2018 (UTC)[reply]

• Unlike other species in the same habitat zone, it tends to sing only during bright morning hours during the breeding season; regardless of season, it does not sing – and even its calling frequency decreases – in cloudy weather. – A bit difficult to read; I would suggest splitting the sentence in two. Also, I would not have "in cloudy weather" at the end of the second sentence, as this is the most important information, and you cannot understand what the sentence is all about until you read it. I would suggest "Regardless of season, it does not sing in cloudy weather, when even its calling frequency decreases" or something similar.

done Cas Liber (talk · contribs) 21:12, 7 May 2018 (UTC)[reply]

• It is fairly common to common in the interior and on adjacent slopes – is this referring to the Sierra Madre del Sur? Maybe add "In the latter," to make this clear?

can't see all the source - @MeegsC: can you shed some light.... Cas Liber (talk · contribs) 00:48, 10 May 2018 (UTC)[reply]

• In the 16th century, Friar Bernardino de Sahagún had reported that a … – This paragraph appears under "Behavior", but it is not about behavior at all but interaction with humans, maybe move it to its own section?

done Cas Liber (talk · contribs) 21:13, 7 May 2018 (UTC)[reply]

• While it seldom associates with mixed-species flocks – earlier you mentioned that it "sometimes joins mixed-species flocks". Is seldom the same as sometimes? Maybe use the same word.

"sometimes" can be highly ambiguous in English, covering everything from "often" to "seldom". changed to "occasionally" Cas Liber (talk · contribs) 09:24, 9 May 2018 (UTC)[reply]

• When describing the nest in detail, you mention the important fact that it is not a typical bird nest but a roofed nest only at the very end. I would mention this fact right before or after the section starts with "The femail alone builds the nest". It would make it much easier to follow the detailed description of how the female builds it.

The mention "over-shaped" implies a roofed structure, so not at end. moved up a bit Cas Liber (talk · contribs) 10:09, 9 May 2018 (UTC)[reply]

• it feeds alongside other birds with no signs of conflict, displaying no hostility towards other species with which it competes – this is somehow conflicting with an observation by Elliott cited in the neotropical.birds.cornell.edu web page: Elliott once observed a pair forage alongside a pair of Slate-throated Redstarts (Myioborus miniatus) during March, yet on another occasion he also saw one male and two female Red Warblers chase off an Empidonax flycatcher that entered their territory. I suggest to add this observation for balance.

added Cas Liber (talk · contribs) 10:06, 9 May 2018 (UTC)[reply]

• A follow up question: You describe its behavior against competing species, but what about members of the same species that cross its territory?

added Cas Liber (talk · contribs) 10:00, 9 May 2018 (UTC)[reply]

• In general, I feel that the article is not as comprehensive as it could be. All of the points below are covered by the https://neotropical.birds.cornell.edu web page, so it should not be a problem to expand accordingly.

• • Iris color, also important. Maybe even bill, tail, wing chord, tarsus lengths, as these are standard measurements (although I understand if you prefer to keep them out for readability reasons).

iris colour added. I have never added the bill, tail, wing chord or tarsus lengths as I feel these are too specialised for (and of little interest to) a lay reader Cas Liber (talk · contribs) 09:22, 9 May 2018 (UTC)[reply]

• • Not sure here, but something to thing about: Add what we don't know about this species, to show why further research is needed. --Jens Lallensack (talk) 17:28, 7 May 2018 (UTC)[reply]

that is generally hard to add unless stated somewhere...and could hold true for the majority of bird species I suspect... Cas Liber (talk · contribs) 09:36, 8 May 2018 (UTC)[reply]

All resolved, many thanks. Supporting now. --Jens Lallensack (talk) 18:04, 25 May 2018 (UTC)[reply]

i found this informations :

This species has a very large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence <20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). Despite the fact that the population trend appears to be decreasing, the decline is not believed to be sufficiently rapid to approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size is very large, and hence does not approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.

@Anass:, in English wikipedia, we can't invent information. If it's not out there already in other sources, we can't add it to the article.

Anass, can you provide the diffs where you nominated the Arabic version? I'd like to compare it to what you were working from (in terms of the English article) at the time. We've added material since you first brought it up, so I presume you've enlarged it over there during their FA process too? This article is of a comparable size and depth to some other biology FAs.

@Anass:: Do you have access to videos or recording for this species? I don't see any in Wikipedia Commons. I can't add what isn't available! As for "saying these things in separate paragraphs", there is a section entitled "Description" that presents a detailed description of the bird, with the adult, immature and juvenile plumages each described in separate paragraphs. There is a section entitled "Voice" that talks about vocalizations. The "Taxonomy" section talks about related species, and there's a separate paragraph in the "Description" section that talks about other species you might confuse it with. The "Parasites and predators" section talks about natural threats, and the "Conservation and threats" talks about human interactions. Each of the things you say is missing is already in the article.

Support and comments from Jim

Just a couple of nitpicks

• Like all New World warblers, the red warbler is an insectivore. appears in the lead but I can't see it in the body text it is supposedly summarising, nor can I see a source. Furthermore, although US sources often give the impression that breeding wood warblers are exclusively insectivorous, some at least take seeds or fruit in their winter quarters, and pine warbler certainly eats seeds even in the US

I removed Like all New World warblers as not in body and not germane to article really Cas Liber (talk · contribs) 23:24, 19 May 2018 (UTC)[reply]

Source review

• Not sure if anybody reviewed the references above, but I had a look regardless. All of the citations are to what I would consider high-quality reliable sources. The vast majority of them are journal articles and books, with a few to websites; all of them appear reliable. In addition, they are all formatted well and the online references show up as working properly on the link-checker tool. In short, I found no issues with the sourcing of the article.

Sabine's Sunbird's comments support

A few comments, nitpicks mostly:

• endemic to the highlands of Mexico, north of the Isthmus of Tehuantepec. Does this apply when the range of one subspecies is to the south and west of the narrowest point of the isthmus?

@Sabine's Sunbird: Hmm. That's directly from the source, which says "Endemic to highlands N of Isthmus. What do you suggest? MeegsC (talk) 22:04, 22 May 2018 (UTC)[reply]

According to this journal article, he was there in 1823. I'll add the link to our article. MeegsC (talk) 08:54, 20 May 2018 (UTC)[reply]

• y isolated two alkaloids in preliminary investigations of the feathers.[31] These render the bird unpalatable; humans find it inedible I wonder if this could be elaborated a bit - humans as a rule don't eat anything with feathers still on!

The alkaloids make the birds unpalatable, not the feathers. I've tried to clarify that; did I succeed? MeegsC (talk) 21:50, 22 May 2018 (UTC)[reply]
