Navigation by stars[edit]

I'm wondering if people know the status of research for birds that use the night sky to navigate, orienting themselves by the rotation of the celestial sphere ([1],[2])? It should probably be added - this isn't my field, though. SamuelRiv (talk) 16:17, 29 August 2010 (UTC)

Good idea! We at WP:BIRD will try to work something in. MeegsC | Talk 00:17, 30 August 2010 (UTC)
Nocturnal migration would certainly be an interesting subject. My layman's understanding is that it has more to do with weather patterns and magnetite bird navigation (essentially the same as daytime navigation) -- but I could be wrong. ~E (talk) 19:55, 26 September 2012 (UTC)

Additional terminology needed, e.g.:

Hmm, if birds fly around the clock, then part of the journey is at night, but the fact that they fly (and make flight calls) at night doesn't make for a separate subject, nocturnal migration, unless there's more to it than that. As for the tropical, etc, yes, the article probably needs to be more global in scope. Chiswick Chap (talk) 13:26, 26 March 2013 (UTC)

Making this a Good Article...[edit]

It seems a terrible pity that this article is still not a GA. I've marked up the uncited paragraphs ... quite a few. The coverage is quite good, however, and the writing of good quality, mostly. Anyone fancy joining me in a collective Good Article push? Chiswick Chap (talk) 10:35, 24 March 2013 (UTC)

GA Review[edit]

This review is transcluded from Talk:Bird migration/GA1. The edit link for this section can be used to add comments to the review.

  • I propose to take on this review. On preliminary inspection, it looks a thoroughly competent article. Cwmhiraeth (talk) 10:38, 9 September 2014 (UTC)

First reading[edit]

A few points:
  • Both the first two sentences in the lead are complex sentences which I consider have too many clauses before getting to the main verb.
  • "... risks of the migration such as predation. Predation can be ..." - Better not to repeat the word "predation" in this way.
  • Now that bird common names are no longer capitalised in Wikipedia, perhaps you should do likewise. I will note the examples I notice here: swallow, (eastwards!), red knot, dunlin, blue grouse, American goldfinch, Arctic tern, Arctic tern again, Manx shearwater, Bar-tailed Godwit, Griffon Vulture, Ruby-throated Hummingbird, Cedar Waxwing, Bar-tailed Godwit again, Osprey, Honey Buzzard, Canada Geese, Whooping Crane,
I think these have all been done now.
  • Bar-headed geese needs a capital!
  • In the section "Long-distance migration" several birds have no scientific names whereas previously you have assiduously provided these.
  • "... feeding sites is a barrier to may also be a barrier" - Muddled sentence.
  • "...forage less on migration" - perhaps "during" for clarity.
  • "...move further to the coast or to a more southerly region." - Perhaps "towards".
  • Where did the red crossbill irruptions occur?
England stated.
  • "This is termed as protandry." Is the "as" necessary? Do you think this paragraph could be better expressed in layman's terms?
  • "With experience they learn various landmarks ..." - The rest of this paragraph is talking about a bird in the singular.
changed to singular.
  • What has the sentence about "watchpoints" got to do with vagrancy?
  • "- usually once a year but sometimes two -" - Maybe "twice"?
  • "Considerable interest has been taken ..." - Into what?
  • Why is "Emlen funnel" bolded?
removed. Chiswick Chap (talk) 13:44, 16 September 2014 (UTC)
I have now finished the first reading. Cwmhiraeth (talk) 09:02, 10 September 2014 (UTC)
@Cwmhiraeth: All comments actioned. Chiswick Chap (talk) 14:15, 16 September 2014 (UTC)

GA criteria[edit]

  • The article is well written and complies with MOS guidelines on prose and grammar, structure and layout. The suggestions I made above have been implemented
  • The article uses many reliable third-party sources, and makes frequent citations to them. I do not believe it contains original research.
  • The article covers the main aspects of the subject and remains focussed.
  • The article is neutral.
  • The article is stable.
  • The images are relevant and have suitable captions, and are either in the public domain or properly licensed.
  • Final assessment - I believe this article reaches the GA criteria and I would like to congratulate the nominator on an excellent article. Cwmhiraeth (talk) 10:54, 18 September 2014 (UTC)
Thank you very much. Chiswick Chap (talk) 13:07, 18 September 2014 (UTC)

Moult migration[edit]

Should this article cover moult migration as well? --Artman40 (talk) 13:23, 8 October 2014 (UTC)

Yes, why not, an interesting minor aspect in species like the shelduck. There are plenty of reliable sources. Go right ahead. Chiswick Chap (talk) 14:09, 8 October 2014 (UTC)
But where to find the sources to work with? --Artman40 (talk) 15:26, 11 October 2014 (UTC)
You're kidding, right? Well, a library; JSTOR; the Internet; bird journals. Chiswick Chap (talk) 16:32, 11 October 2014 (UTC)
Shelduck are not the only animals to migrate before moulting. Many birds migrate to reeded areas and other wetlands. Just reliable sources are needed. --Artman40 (talk) 22:25, 11 October 2014 (UTC)
You are free to seek examples as you please; finding sources is the normal and principal work of Wikipedia editors, that's what we do here. Shelduck are however certainly the best known example. Chiswick Chap (talk) 08:00, 12 October 2014 (UTC)


The following has been proposed: "Around 3000 BC, Kalidasa tells about the 'valaha' birds going back to Manasarovar from south India in the shape of a garland after breeding.[1]" This doesn't seem exactly to be supported by the source as translated; possibly it's clearer in another translation or in the original. Help appreciated. Chiswick Chap (talk) 15:51, 12 October 2014 (UTC)
