# Talk:Black-capped chickadee

... similar to other bird pages such as House Finch, etc. 24.113.167.160 18:11, 6 May 2007 (UTC)
It would be interesting to see some information on variations of vocalization among different population groups which have been geographically isolated from each other. Also the evolution of the Mating call, has it changed over time? is there any selection  that takes place for one call length versus another length or frequency? if the call is uniform across all populations then is their another phenotypic trait that has a more desirable characteristic for a higher reproduction rate or fitness level such as color or spots?Crissinger.11 (talk) 02:40, 1 October 2014 (UTC)

Can there be a section full of their predators that’s easy to find, please? 24.92.58.235 (talk) 14:04, 16 May 2022 (UTC)

User:Richlitt is insistent that the name of this chickadee be translated into the Abenaki language, a language currently spoken by about 1,800 people in Canada and the United states (about 0.0005 percent of the combined population).  Moreover, the bird's range covers much of Canada (where there are about 60 Indigenous languages) and the United States (where there are about 175 Indigenous languages). No doubt many of those 235 languages also have a translated name for this bird, and to that end, User:Richlitt is welcome to create the article, "List of Indigenous translations for the chickadee"...but on this particular article--with no intent to trivialize the Abenaki language--its inclusion is out-of-scope and irrelevant.

Yes, those exact arguments. I agree. --Elmidae (talk · contribs) 18:47, 28 February 2023 (UTC)

Indeed. - UtherSRG (talk) 21:52, 28 February 2023 (UTC)

Does anyone have access to Peterson Field Guide for the Birds of Britain and Europe  that supports the claim in the Taxonomy section? As yet I've not been able to find a reliable source - I've found some online discussions about it, but nothing from a WP:RS. As far as I can tell, they were always considered separate species by the AOU and the IOC. grungaloo (talk) 18:51, 22 January 2024 (UTC)

Am I missing something?  "Males and females ... can also be distinguished based on a combination of weight, tail length, and tarsus length. Males have ... a tarsus length of 16–17 mm (0.63–0.67 in). Females are on average slightly smaller, with ... a tarsus length of 16–17 mm (0.63–0.67 in)."
Can we remove mention of "tarsus length" from this section? CbonnerNH (talk) 21:59, 28 February 2024 (UTC)

Fixed. pillowcrow 23:42, 28 February 2024 (UTC)
I've reverted the change but fixed the underlying issue. The range of tarsus lengths is the same, but the average tarsus length is different between males and females. Females have ones on average .4 mm longer, so it does factor into the calculation to determine the sex. grungaloo (talk) 23:50, 28 February 2024 (UTC)
Nope - I was wrong. I was using a source which referred to the original study and it misinterpreted it. Reading that actual study does say that tarsus length is not a factor. I've restored the change made by pillowcrow. grungaloo (talk) 00:41, 29 February 2024 (UTC)
