GA Review

[edit]

This article has been nominated as a Good Article. I have reviewed it under the guidelines for Good Articles and have the following comments:

  • Referencing is adequate, although one of the references (IUCN) is represented by a bullet rather than a linked reference number like the others. This is a relatively minor issue.
  • There is no problem with licensing issues on the pictures, and the pictures illustrate the subject matter very well.
  • The article is comprehensive, and I do not see any major deficiencies in the coverage of the subject matter.
  • The article is written from a neutral point of view.
  • The prose is another matter. The article needs a significant copyedit before it can be promoted as a Good Article. Some random examples taken from the article include: (by no means a complete list)
    • It is called (minha) pachang, where minha is a qualifier meaning 'meat' or 'animal', in Pakanh, (inh -) inhulg in Uw Oykangand, and (inh -) anhulg in Uw Olkola, where inh- is a qualifier meaning 'meat' or 'animal' three aboriginal languages of central Cape York Peninsula
    • The tail is black with a bright red subterminal panels in the lateral tail feathers.
    • As they reach maturity, males will replace their yellow tail feathers with red ones as they moult, it takes approx 18 months to grow into its male feathers.
    • They are generally rather shy of humans. Flight is a rather slow with deep flapping.
    • The current Australian restrictions on commercial exports from Australia are not imposed by CITES, (a standalone paragraph leading me to think that the rest of the sentence/paragraph was deleted somewhere)
    • The Red-tailed Black Cockatoo is the most often seen of the Black Cockatoos to captivity,[30] and can be hardy and long lived if given plenty of space.
    • The male will start to "sing" and strut along his perch ending in a jump and a flash of red tail feathers toward the female who most the time will reply by biting him (defensively ),once the female has one egg in her nest she will not lay another , the egg takes about 30 days to hatch , the babies eyes will open around 3 weeks and the yellow down will show black pin feathers at about 6 weeks , best time for had raising is at about 10 weeks when their black feathers are in place but the tail feathers are still short , the baby will fledge after about 4 months.
  • The article needs some cleanup according to WP:MOSNUM as many of the units of measure are given in metric only

For the reasons outlined above, I am failing the nomination at this time, although when those suggestions have been implemented, you are free to re-nominate the article at any time in the future. Good luck. Neil916 (Talk) 19:39, 10 August 2007 (UTC)[reply]

Gosh, I never even saw it referred. Oh well, I knew about alot of those. Time to get stuck into it I guess....thanks for the pointers...(2nd time that's happened to me)cheers, Casliber (talk · contribs) 21:37, 10 August 2007 (UTC)[reply]

To-Do List

[edit]

Please enter material needed to get to FA here...cheers, Casliber (talk · contribs) 09:38, 11 August 2007 (UTC)[reply]

  • Find out and enter accurate information on aviary trade value in Oz and O/S -especially current Aus and O/S value.

AU$2500 off a breader is a true value in Australia , wholesale down to AU$1800 , pet shops up to $4500 ( RedTailBreader)

  • Would love to find out how the NT 'farming' program is going but this is proving elusive online.

NT Redtail Farm's caretaker put in a lot of info on this page that has been attributed to other sources , email me for info ( RedTailBreader)

  • more aboriginal names/folklore
  • published material on vocalisations

ill see what i can do about recording there different moods probably video would be best ( RedTailBreader)

  • It would be really cool to get a really nice photo too.

in the proses of adding the baby's at different stages of growth , will add more as the baby grows

  • Blue redlinks (not essential but very helpful for FAC)


a couple of errors i've found ( RedTailBreader), i think it took 2 years of editing to correct grammar and set out when i typed out large blocks of text last time , so here's what i think needs editing so it can be debated before changing ( my own observations once again no quote's )

  • "the slightly smaller females are brownish-black" with yellow barring

the size difference between the adults is +/- 25mm ( inch) some females are larger than the males %50 / %50, and colour is identical but change colour the duster they get ( lack of rain will turn them grey ( dust))

  • The tail is also black with "two lateral bright red panels". Females are "brownish black "

the red panel is a solid band across the tail feathers , anal feathers cover the red panel braking it into 2 panels , and the brown again ( the observed bird might have just had a dust bath ), the external most male feathers are only 1/2 red ( all males) and the centre ones have a red spot <(not seen much , might be only one species

  • Juvenile Red-tailed Black Cockatoos resemble females until puberty, which occurs around four years of age, but have "paler yellow barred underparts"

the underparts can be the same as there mum or a orange tint through the yellow ( some species ,i cant name the species by sight, the birds i look after were collected in the NT , lol , no subspecies for NT so are a group of interbreeding between WA's and QLDs and NSW's )but the orange tint with the males happens to all males from a pair (4 sets ) , and not seen in other pairs baby males ( seen in the lol male pic titled " eating Casuarina seeds" , its a juvenile male )all juvenile males beaks turn from bone to grey before there feathers change colour

  • ending in a jump and a flash of red tail feathers toward the female who will most often reply by defensively biting him."add here" [48]

when the female submits she will lower a wing and squat on the perch to allow the male to climb on her back ,where once in position the male will copulate with his wings open almost standing tall with a "Kak ing" call ( might get some video of the breading ), also , the skin around the the female's eyes changes from a light grey to black with a tint of red as she comes into breading season ,and mating normally happens during the day ,around the full moon

  • A clutch consists of 1 "to 2" white eggs

rarely 2 eggs ( never seen 2 eggs layed at the same time , but have seen nests with 6 egg in one year when they dont sit )

  • They also feared that since adults mate for life, a bird whose partner was taken may not mate again.[61

a false statement , old partner can even be in the next cage im declaring a conflict of interest as this paragraph "wild v's caged " and i care take for a flock under the NT management plan

  • Cultural depictions

coastal aboriginals associate a large flock of red tails as a bad omen ( death coming ) central aboriginals associate a large flock of red tails as good omen ( water coming (rain)) do red tail flock when fleeing cyclones ? —Preceding unsigned comment added by RedTailBreader (talk • contribs) 11:06, 10 August 2010 (UTC)[reply]

Aviculture Captive breeding guidelines may be found in Husbandry Guidelines for the Red-tailed Black Cockatoo (Bennett, 2008).[71] a pug for a book ??????? should be removed


its a bird that demands attention and will repay attention 2 fold with affection, if you want a bird you just feed and ignore ,this is not the bird for you unless they were not hand raised and you plan on breading them , with bolt cutters for a face they can be very destructive to furniture , wire's, walls and fingers ( fingers look like peanuts ?), lol, and will enjoy chewing timber , rubber , plastic , and will digest some , cage position should allow at least 1 hour direct sun a day , since there sun worshippers ( screech at sunrise and sunset ) morning sun is best to warm them up but afternoon sun will do , and in a cool shaded area in the heat of summer , being a black bird shade must be provided 11 am - 3pm on a hot day , a 1/2 covered large cage will also work and will also allow access to rain that the redtail black cockatoo loves, a sprinkler on a warm day is just as good , they like to be up high , so raise there cage so the main perch is above eye level, you will need a cage that the bird can stretch its wings in , for a red tail the smallest cage would be 1m x 1m x 2 with 3mm diameter wire , they will destroy a cage made from 2mm wire or smaller

food , natural food is best but they are fussy about the ripeness of the gum tree nuts they eat ,but do well on a 50% 50% mix of grey sunflower and parrot mix , with small amounts of fresh veggies / nuts regularly ,Corn , silver beat , broccoli , peas , sprouts , these don't attract ants like fruit does , keep an eye on your birds craps , you an tell a lot about what to feed it by this method , too much greens / fruit gives them diarrhoea , just like us , lines in the feathers are stress lines , the bird was stressed as the feather grew , regular spaced lines mean the bird was regularly staved , fed every 3 days with enough food for 2 days ,a snake on the out side of the cage is enough to cause a line , —Preceding unsigned comment added by RedTailBreader (talk • contribs) 07:46, 15 August 2010 (UTC)[reply]

Subspecies

[edit]

The photograph / picture in the article showing the sexual dimorphism in the graptogyne subspecies says that it is from Western Australia. However, graptogyne doesn't occur in Western Australia. I'm not sure of the origin of this photo. Either, the picture is not from Western Australia, or the picture shows one of the three subspecies that do occur in Western Australia (i.e. naso, samueli, macrorhynchus). Does anyone have any thoughts on this one? GCBabbler 02:03, 10 October 2007 (UTC)[reply]

Dammit, I'd forgotten 'bout that one. I had tried to find out whether it was naso, samueli or what and never did. Oringial pic says it in WA but doesn't specify where. Best just remove subsp tag for teh mo' until we find out. cheers, Casliber (talk · contribs) 02:47, 10 October 2007 (UTC)[reply]
I tried looked at the female tail to give a clue which subspecies it might be, but there's not enough. No matter. The key point from the picture is to show the sexual dimorphism, and not the difference between subspecies. Cheers GCBabbler 04:29, 10 October 2007 (UTC)[reply]

"Relationship to Man" is an otherwise unseen "collect-all" section

[edit]

There are at least 4 threads here:

1. birds as part of nature (i.e. agricultural pests, which is the character of the birds, and has nothing to do with man's actions toward them)

2. conservation, i.e. man preys on the birds and man is now responsible for them; this subsumes the smuggling section

3. birds not as part of nature: as pets, collector and display animals (zoos, etc)

4. man's culture and media, which have nothing to do with birds in nature or birds in captivity

No other bird or animal article that I've read has this top level section. I think as we move to a standard format, we should restructure this - a relatively minor adjustment of secton levels (content stays in the same relative location(s))

Touching a FA article is a special responsibility, I'm going to see if anyone comments Sbalfour (talk) 21:05, 11 November 2012 (UTC)[reply]

I agree it is a somewhat....heterogeneous section - what would you propose? I've often made the conservation sections a subsection of distribution and habitat. Casliber (talk · contribs) 21:56, 11 November 2012 (UTC)[reply]
Ok, I'll take a whack at it. The comment about digging up peanuts at the top of the section goes under "Diet", right under the sentence about learning to eat introduced plants. The top level section "Relationship to Humans" gets deleted. The subsections below it become top level sections, except "Illegal Smuggling" and "Proposed NRETA plan" move to subsections under "Conservation Status". I'd normally move "Conservation Status" under "Distribution and Habitat", unless it's lengthy (like this case, so leave it as a top level section).Sbalfour (talk) 00:57, 12 November 2012 (UTC)[reply]
Ok go for it. Casliber (talk · contribs) 02:26, 12 November 2012 (UTC)[reply]

"proposed NRETA plan" section now obsolete?

[edit]

The plan was proposed in 1997; as of 2012 it's not implemented, and apparently abandoned in favor of other options, though never officially "killed". This section reads like a current (now obsolete) news item. In an encyclopedic article, we shouldn't we including "proposals". I'd propose (no pun intended) we find a link to a description of the plan (if there is one - or just use one of the existing reference links), delete the section, mention the plan in a sentence and let them follow the link. Sbalfour (talk) 21:39, 11 November 2012 (UTC)[reply]

Not sure - it is a prominent idea which has cropped up from time to time, so discusson of it somewhere is good. Burying it as a link makes accessibility poor. I guess what I'm saying is I am opposed to deleting it outright but do support making it more past-tensey. Casliber (talk · contribs) 21:58, 11 November 2012 (UTC)[reply]
We have to fix this - NRETA department no longer exists - it's now about 5 separate departments. No mention of the C. banksii macrorhynchus plan can be found on the Northern Territory government website, though it does list implemented recovery plans for two of the other subspecies. I say we need an authoritative citation to that plan's continued existence (not a popular news article), or we delete the section. Actually, replace the section with descriptions of the two listed recovery plans. In fact, I couldn't find a listing of this subspecies at all in the lists of endangered species on the website.
Sbalfour (talk) 23:16, 11 November 2012 (UTC)[reply]
Thinking on my feet here - how about moving the quota plan section into a footnote, and substituting a paragraph about the existing recovery plans for the two (other) vulnerable subspecies, mention the quota plan for the northern subspecies, and let them follow the reference to the footnote for details on it?
Sbalfour (talk) 02:49, 13 November 2012 (UTC)[reply]
I can live with this. I'd hate to see it disappear entirely but concede the point about it being archived, so footnote is ok. Casliber (talk · contribs) 11:55, 15 November 2012 (UTC)[reply]

2nd paragraph of intro duplicates Description, Distribution and Habitat sections; "tone" of intro a little dry

[edit]

The intro is a little too detailed, in particular the morphological description which is already found in the "Description" section. I propose shortening it and letting it read a little more generically: "It's a large mostly black cockatoo often seen in large flocks over woodland areas." That's a little too colloquial, but more in the style of a riposte (i.e. What's a Red-tailed Black cockatoo?). The opening paragraph should invite the reader to proceed to the rest of a very informative article.

Does the cursory reader want to know or even understand what it means to 'conserve' a zoological name? That phrase probably should get moved to the "Taxonomy and naming" subsection. Sbalfour (talk) 16:21, 12 November 2012 (UTC)[reply]

All rejigging looks good so far. NB - your signature is oddly formatted. I think you may need to tweak it in your "my preferences" tab. The lead is supposed to summarise the contents of the article, so there is a tendency to repeat info in it.Casliber (talk · contribs) 19:09, 12 November 2012 (UTC)[reply]

WP:URFA/2020 notes

[edit]

Have been going through the 2006 and 2007 FAs remaining at WP:URFA/2020A. This one looks to be in fairly good shape, but a few notes, mainly conservation updates:

  • There's some newer population estimates for the southeastern red-tailed black cockatoo
  • "Baker, Joe (2007). "Rare, unusual, difficult to find:Black Palm Red Tail and Gang-Gang Cockatoos, Blue Napes, Hawk Heads". Birds of Paradise Aviaries. Archived from the * original on 11 September 2007. Retrieved 26 August 2007." - I don't know that this would be considered high-quality RS under the more modern FA standards
  • "Goodfellow, Denise Lawungkurr. pers. comm." - shouldn't be citing personal communication
  • "The large and powerful bills of these birds can quickly and easily open a Brazil nut (normally requiring crushing in a vise or pounding with a hammer), shearing it as neatly as a laser. They can also demolish a whole coconut with husk in 3 days." - unsourced addition to article
  • Any chance of an update on the captive prices?

This is still in good shape, just needs some tuning up Casliber although there's no rush here. Hog Farm Talk 02:12, 21 June 2023 (UTC)[reply]
