 | This is the sandbox page where you will draft your initial Wikipedia contribution.
If you're starting a new article, you can develop it here until it's ready to go live. If you're working on improvements to an existing article, copy only one section at a time of the article to this sandbox to work on, and be sure to use an edit summary linking to the article you copied from. Do not copy over the entire article. You can find additional instructions here. Remember to save your work regularly using the "Publish page" button. (It just means 'save'; it will still be in the sandbox.) You can add bold formatting to your additions to differentiate them from existing content. |

Diet[edit]
It feeds at night, mainly on grasses but also on leafy shrubs and low trees. It has a nickname "stinker" because mature males have a distinctive curry-like odour.

Core Body Temperature[edit]
The western grey kangaroo is a nocturnal species that has a core body temperature that varies based on daily ambient temperatures. On days that were expected to be hotter, the kangaroo’s core body temperature was much lower than days that were cooler [1]. This reduced summer body temperature is thought to allow the species to conserve energy during a time when food availability is low. In another study conducted to explain why the western grey kangaroo’s core body temperature decreases as summer progresses, researchers found that as surrounding temperatures increased by 21°C during the day, wild kangaroos’ core body temperature decreased by ~1°C [2]. Researchers also discovered that changes in core temperature were tightly controlled during active hours at night [3]. This species is known to use a unique evaporative mechanism called saliva spreading to cool themselves down, but they appear to only use it during exercise, it was not frequently observed [4].

Reproduction and development[edit]
The western grey kangaroo lives in groups of up to 15. The males compete for females during the breeding season. During these "boxing" contests, they lock arms and try to push each other over. Usually, only the dominant male in the group mates. The gestation period is 30–31 days, after which the incompletely developed fetus (referred to as a joey) attaches to the teat in the pouch for 130–150 days. Females sexually mature at 17 months while males mature at around 20 months.
