The bronze grass skink, bronze mabuya or speckled forest skink (Eutropis macularia), is a species of skink found in South and Southeast Asia. It is a common, but shy, ground-dwelling species that is active both day and night.
The bronze grass skink has a cylindrical body, dorsal scales with 5–8 keels, and smooth ventral scales. A pair of dorso-lateral bands start from above the eye and extend to the base of the tail. As with other Eutropis species, the scales are keeled. The snout is short, obtusely keeled and acuminate, and the lower eyelid is scaly. The nostril is located behind the vertical suture between the rostral scale and the first labial scale. The ear-opening is oval, about the same size as a lateral scale, or a little smaller. The dorsal, nuchal, and lateral scales have five to seven sharp keels, and there are 26 to 30 scales, approximately equal in size, round the middle of the body. The adpressed limbs meet or overlap. The digits are short and the lamellae between them smooth. The tail is 1.25 to 1.75 times the length of the head and body. Brown or olive-brown above, sides darker and usually with white black-edged spots; back uniform, or black-spotted... Wikipedia →

Likely
About 40% of wildlife watchers report a Bronze Grass Skink sighting in Cat Tien National Park on a given day, based on 46 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 11th most-seen of the 45 reptiles we can rate there. Over three days the chance rises to about 80%, and over a week to over 90%, if each day is a fresh chance.
January
In that month about 60% of wildlife watchers report a Bronze Grass Skink in Cat Tien National Park on a given day, against under 5% in August and September, the lowest months. That is one of Cat Tien National Park's driest months, with about 30 mm of rain against 490 mm in July.
Between 4 and 7 am
Across all the parks we cover, that three-hour window holds the most Bronze Grass Skink sightings with a recorded time, and about 6 in 10 of them come between 6 am and 6 pm: it is most active around dawn and dusk.
Yes
Of the 2 parks where we can rate Bronze Grass Skink sightings, Cat Tien National Park has the highest daily chance: about 40%. Next come Kaeng Krachan National Park (Thailand, about 20%).
GBIF citizen-science records
It is estimated from how often the Bronze Grass Skink is recorded against all the reptiles logged in Cat Tien National Park (46 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
