Did you know that lots of desert animals utilize burrows? Desert tortoises, burrowing owls, desert kit foxes, badgers, and other small mammals spend a lot of time underground and may even use each other’s burrows if they’re found vacant. When our biologists perform surveys, they work like detectives looking for clues to see who might be living there! Burrows created by desert tortoises have a distinctive half-moon shape, but if they see feathers or whitewash outside of the entrance, that may be a clue that an owl occupies that burrow! If they find suspiciously large claw-marks around the opening of a burrow, it’s likely a mammal living inside! Part of the fun of field biology is getting to work backward to understand the ecology of a site, which is why…

Did you know that there is no precise method of visually determining a tortoise’s age? Some use growth rings on the scutes of the carapace (top shell) to indicate age, but just like growth rings on a tree, a tortoise can develop no rings, or up to several growth rings per season. Others use forelimb size or shell length by measuring the midline carapace length (MCL) to estimate age, but these methods can still be inaccurate, as growth rates and length can vary year to year depending on food availability and environmental conditions. Upon hatching, tortoises emerge at around 45 mm (< 2 inches), and can grow up to 360mm (14.17 inches)! Our biologists estimate age in the field using carapace length at the midline (MCL) paired with other…

Did you know that one of the ways to determine the sex of a tortoise is by chin glands? Chin glands become present on males at sexual maturity and serve as chemical and visual signals to other tortoises. Dominant males have chin glands that are larger than other males’ and contain more testosterone. The more you know…

Did you know… that female tortoises can store sperm for up to 5 years? Because of this, they don’t need to mate each year to lay a clutch (of eggs). Also because of this, a single clutch can be from multiple paternal partners.

Did you know…. that the top shell of the desert tortoise, known as the carapace, takes about 5-8 years to reach full ossification (hardening of the shell)? During these first several years they are very vulnerable to various predators, including ravens, coyotes, kit fox, badgers, gila monsters, roadrunners, snakes and more.
