The desert horned lizard (Phrynosoma platyrhinos) is a species of phrynosomatid lizard native to western North America. They are often referred to as "horny toads", although they are not toads, but lizards. They typically range from southern Idaho in the north to northern Mexico in the south. These lizards can generally be found in areas with desert climates throughout western North America.
Changes in the environment due to climate change can trigger shifts in the geographic ranges of animals. Phrynosoma platyrhinos has experienced some changes after the Last Glacial Maximum (LGM) which ended approximately 21,000 years ago. The end of the LGM resulted in the expansion of deserts throughout western North America, and with that expansion Phrynsoma platyrhinos had more areas suitable for them to live in. At the end of the LGM P. platyrhinos was able to expand north into the Great Basin, which is now part of their current geographical range.
There are two subspecies which are found in a different geographic ranges: the northern desert horned lizard (Phrynosoma platyrhinos platyrhinos) ranging in Idaho, Wyoming, Utah, Nevada, the Colorado front range... Wikipedia →

Likely
About 50% of wildlife watchers report a Desert Horned Lizard sighting in Joshua Tree National Park on a given day, based on 604 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 6th most-seen of the 39 reptiles we can rate there. Over three days the chance rises to about 90%, and over a week to over 90%, if each day is a fresh chance.
May
In that month about 80% of wildlife watchers report a Desert Horned Lizard in Joshua Tree National Park on a given day, against under 5% in January, the lowest month.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Desert Horned Lizard 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 3 parks where we can rate Desert Horned Lizard sightings, Joshua Tree National Park has the highest daily chance: about 50%. Next come Death Valley National Park (United States, about 50%) and Grand Canyon National Park (United States, about 10%).
GBIF citizen-science records
It is estimated from how often the Desert Horned Lizard is recorded against all the reptiles logged in Joshua Tree National Park (604 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.
