Eurasian tree sparrows exhibit various physiological adaptations due to seasonal changes in temperature and photoperiod. When exposed to shorter photoperiods and colder temperatures during winter seasons, and with temperature having the greatest effect, Eurasian tree sparrows exhibited increased body mass, increased BMR, and increased enzyme and hormone activity (Li et al. 2020). Increasing body mass allows these birds to store more energy while their increasing basal metabolic rate is due to a higher amount of energy needed to maintain their body temperature in colder conditions. Another study found that Eurasian tree sparrows also exhibit higher levels of thyroid hormone T3 levels in the winter, which is a hormone that helps regulate the body’s use of energy. The birds’ increased T3 levels can be correlated with their increased basal metabolic rate as T3 can help play an important role in the regulation of heat production (Zheng et al. 2014)

Lead

 * lead has been updated to reflect the added content material
 * the leading sentence does a good job of encompassing the material to come
 * the article lead does reference the sparrow as a whole, however, the rough draft is not about the lead paragraph
 * new information is introduced to the article that benefits the article as a whole
 * this rough draft is concise and does a good job of staying informative but easy to read

Content

 * I would improve the rough draft by adding hyperlinks for the specific material that may be difficult to understand such as photoperiods and BRM (what are these, why are they relevant to the sparrow's metabolic rate?)
 * content does not reflect any obvious opinions or inaccurate material
 * the content is fairly up to date with the article citing of 2014
 * I would find another way to introduce the second article rather than "another study found" i feel your sentence would be more concise just starting with "Eurasian tree sparrows also exhibit..."

Overall Impressions

 * this rough draft is a great initial start; the material is new and well introduced and will benefit the main article greatly.
