Talk:Chimney swift
Threatened
[edit]According to Ministry of Natural Resorces (MNR Province of Ontario, Canada) This bird has seen a 30% decrease in population over the past 13 years. Currently, there is a conjunctive effort with Bird Studies Canada and a voluteer organization named "Ontario Swift Watch" which is identifying and observing nesting/roosting sites in preparation for protection measures. The MNR has declared the Chimney Swift as "Threatened" as of October 30, 2010.
I am not a bird enthusiast, and am unfamiliar with thier conservation status rankings. I do not know how to update such a status here on the wiki, and I would think that someone better qualified would be better suited to look into the status, statistics and possibly make the appropriate changes to the article. 24.235.198.91 (talk) 02:52, 31 October 2010 (UTC)
Range map
[edit]A range map would be useful, similar to this one: [1], from here:[2] ~E 15:31, 8 October 2012 (UTC) Thanks. ~E:74.60.29.141 (talk) 17:35, 19 December 2012 (UTC)
Fovea
[edit]![](http://upload.wikimedia.org/wikipedia/en/thumb/f/fb/Yes_check.svg/20px-Yes_check.svg.png)
I clarified the fact that this swift has two fovea per eye. I relied on the following source, which I did not add; a different source is probably preferred:
- Lederer, Roger. "The Nervous System and Senses". Lectures. Ornithology.com.
Somebody might want to expand just a little about the 'bifoveal vision'. I would consider doing this, but thus-far all that I know about the subject is from that source. By the way, some birds are trifovial. ~Eric:71.20.250.51 (talk) 21:38, 14 January 2014 (UTC)
- I added a footnote with link to the Bird vision article; there probably is a better solution, however. ~E:71.20.250.51 (talk) 19:26, 15 January 2014 (UTC)
