Lophognathus gilberti, also known commonly as Gilbert's dragon, Gilbert's lashtail, or Ta-ta lizard, is a species of lizard in the family Agamidae. The species is endemic to Australia. The specific name, gilberti, is in honor of English naturalist John Gilbert.
L. gilberti is found in the following Australian states and territories: northern Northern Territory, northwestern Queensland, and northern Western Australia. L. gilberti is found in a variety of habitats including coastal sand dunes, shrubland, savanna, and forest, and it has also been found in agricultural and urban areas.
L. gilberti is terrestrial and semi-arboreal. L. gilberti is oviparous, and sex determination is temperature-dependent. Boulenger GA (1885).

Likely
About 40% of wildlife watchers report a Gilbert's Dragon sighting in Litchfield National Park on a given day, based on 20 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 9th most-seen of the 24 reptiles we can rate there. Over three days the chance rises to about 70%, and over a week to over 90%, if each day is a fresh chance.
September
In that month about 50% of wildlife watchers report a Gilbert's Dragon in Litchfield National Park on a given day, against about 10% in January–March and November, the lowest months. That is one of Litchfield National Park's driest months, with about 15 mm of rain against 400 mm in January.
Between 1 and 4 pm
Across all the parks we cover, that three-hour window holds the most Gilbert's Dragon sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 2 parks where we can rate Gilbert's Dragon sightings, Litchfield National Park has the highest daily chance: about 40%. Next come Kakadu National Park (Australia, about 30%).
GBIF citizen-science records
It is estimated from how often the Gilbert's Dragon is recorded against all the reptiles logged in Litchfield National Park (20 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.
