Welcome!

Hello, CharlieBrownCB5, and welcome to Wikipedia! My name is Ian and I work with the Wiki Education Foundation; I help support students who are editing as part of a class assignment.

I hope you enjoy editing here. If you haven't already done so, please check out the student training library, which introduces you to editing and Wikipedia's core principles. You may also want to check out the Teahouse, a community of Wikipedia editors dedicated to helping new users. Below are some resources to help you get started editing.

Is this working?CharlieBrownCB5 (talk) 15:34, 11 March 2016 (UTC) CharlieBrownCB5 (talk) 15:34, 11 March 2016 (UTC)

Yes it is Mcb1011 (talk) 15:37, 11 March 2016 (UTC)

The Rufous collared sparrow wiki page overall has a good description of the species and its range and habitat, and on feeding and breeding behavior. There is a lot of information on its singing and vocalizations. I would like to see the Ecology heading split into separate sections on feeding, breeding, range, and habitat.

Sounds good, just remember not to overdo it with the number of sectionsMcb1011 (talk) 15:55, 11 March 2016 (UTC)

Hi Charlie, please complete your evaluation of the article by commenting on its history and talk pages. Please post to my talk page whether you would like to be assigned this article for your work this semester. Rico.schultz (talk) 18:25, 18 March 2016 (UTC)

When viewing the history for the Rufous collared sparrow wiki page, I noticed there were over 500 edits, the oldest being from August 2006, and most recent being December 2015. It was hard to say exactly how many users were involved in the revisions, but it appears to be dozens. When viewing the Talk page, it appears this species is part of WikiProject Birds. There is no activity I can observe since May 2014.CharlieBrownCB5 (talk) 20:46, 3 April 2016 (UTC)

Charlie, your change to the symporter article, illustrating how uptake of amino acids occurs in symporters whose action is driven by a sodium gradient created by the ATPase, is fine but not quite grammatical. Revise please! I'm surprised that this is the only citation in the article.Rico.schultz (talk) 02:01, 4 April 2016 (UTC)

Rufous-collared sparrow

Physiology

The physiology of an organism is responsible for regulating vital functions such as osmoregulation, thermoregulation, metabolism, digestion, and the exchange of gases. These functions are essential not only for survival but play a major role in determining things such as habitat, diet, distribution, and the behavior of an organism.

Osmoregulation

The Rufous-collared sparrow relies on its kidneys for osmoregulation. It is able to tolerate a wide range of salt intake despite not having a salt gland, however the metabolic cost in energy is too great to maintain the necessary osmoregulatory processes.

It has been shown that under conditions of higher slat intake, the mass of the kidney and heart can increase up to 20%. This response in organ size causes an increase in basal metabolic rate (BMR) by up to 30%. As a result, the Rufous-collared sparrow tends not to inhabit marine environments such as salt marshes ^[1].

Thermoregulation

Due to its non-migratory behavior, as well as its tendency to be found from high elevations down to sea level, the Rufous-collared sparrow experiences a wide fluctuation in temperature throughout its range each year for which it has adapted to compensate for. Strategies used to acclimate to changing seasonal temperatures include limiting the amount of evaporative water loss (EWL) and increasing metabolic rate.

Total evaporative water loss (TEWL) has been measured to be high during summer months, which may help prevent overheating, and low during winter months ^[2]. In response to cold temperatures, both basal metabolic rate (BMR), and maximum metabolic rate (MMR) have been shown to increase^[3],^[4].

Hey Charlie, everything looks good but I would consider removing the definition of physiology in you edition because it seems unneeded if you're specifically talking about the sparrow. I would also specify in the thermoregulation section if the results of testing TEWL was unique in rufous-collared sparrows or if it is commonly seen in other birds as wellMcb1011 (talk) 04:15, 29 April 2016 (UTC)

@CharlieBrownCB5: Charlie, thanks for your helpful comments on Matt's Gentoo penguin draft contribution! Rico.schultz (talk) 13:19, 29 April 2016 (UTC)

@CharlieBrownCB5: Charlie, I see that you have posted your contribution on the talk page for WikiProject_Birds. Well done! I suggest further that you make more direct contact with the editor Pvmoutside, just put a short note on their talk page requesting that they look at what you've put up... you could do that after you have published if you want to be efficient.
