- The page saysTemperate broadleaf and conifer mountain forests
- The source says
Pygathrix roxellana is found in temperate broad leaf and conifer forests ... These monkeys live in mountain forests all year long
Note: ADW's elevation for that habitat is 1,600 to 4,000 m; the line uses the wider, more recent 1,000–4,100 m from Fan et al. 2018 - The page saysAnimal Diversity Web records a head-body length of 570 to 760 millimeters with a tail of 510 to 720 millimeters
- The source says
These monkeys are reported to range from 570 mm to 760 mm in head and body length. The tail is between 510 and 720 mm.
- The page saysBoth sexes carry golden fur across the belly, forehead and neck, while the rest of the coat runs grayish-black in males and brownish-black in females
- The source says
Males and females have a golden belly, forehead and neck. Males have grayish black on the nape, shoulders, arms, back, head and tail. In females, these parts are brownish black.
- The page saysIts nose is flattened, with forward-facing nostrils and two flaps of skin that form peaks almost touching the forehead
- The source says
The nose is flattened, with nostrils facing forward. Two flaps of skin on the widely opened nostrils form peaks that almost touch the forehead.
- The page saysIn winter the menu narrows to bark and lichen
- The source says
During the winter, however, these monkeys switch to a more limited diet of bark and lichen.
Note: the earlier 'when snow buries the mountain' was cut: no source in the pack mentions snow - The page saysdangerLevel: Low
- The source says
Economic Importance for Humans: Negative These animals have no known negative effects on humans.

- The source says
Primary Diet herbivore herbivore folivore folivore lignivore
- The page saysmales and females often trade whines and shrills while they eat
- The source says
This is particularly true of whines and shrills, which are often exchanged by males and females while they are eating.
- The page sayswith no body or facial movement to show who is calling
- The source says
An interesting aspect of golden monkey vocalizations is the ventriloquist-like absence of any body or facial movement.

reducing skin temperature by an average of 3.2°C through a cutaneous vasoconstriction to decrease heat loss
Note: 'narrows the blood vessels' paraphrases 'cutaneous vasoconstriction'; the tagline drops the 'average of 3.2°C' figure, which the body keeps; the quote's 'average' attaches to the 3.2°C figure, which this phrase does not give; the body keeps both - The page saysburns 14 percent of its body mass getting through a winter

Monkeys often slept in the lower stratum of the tree canopy, avoiding the upper canopy where it is cold and windy.
Note: 'rather than ... above' paraphrases 'avoiding the upper canopy'; 'rather than ... above' is the quote's 'avoiding the upper canopy'; the cold and wind are the quote's own words - The page saysThey also formed larger sleeping clusters at night than during the day

They formed larger sleeping clusters at night than in daytime.
- The page saysmost often adult females clustered with juveniles

The most common types of night-sleeping clusters were adult females and juveniles, followed by adult females with other adult females.
Note: the second, less common type (adult female pairs) is left out; the source's 60.2% covers both together, so no figure is given

How the table was made: a writer drafted the profile from these sources and logged each claim with its quote, a reviewer with nothing but this table checked every sentence said no more than its quote, and a script confirmed each quote appears word for word in the source. The method is in the site'sAbout page.
