Pogona is a genus of reptiles containing six lizard species which are often known by the common name bearded dragons. The name "bearded dragon" refers to the underside of the throat (or "beard") of the lizard, which can turn black and puff out for a number of reasons, most often as a result of stress, or if they feel threatened. They are a semi-arboreal species, spending significant amounts of time on branches, in bushes, and near human habitation. Pogona species bask on rocks and exposed branches in the mornings and afternoons. Their diet consists primarily of insects, vegetation, and occasionally small rodents. They are found throughout much of Australia and inhabit a wide range of environments, such as deserts, shrublands and Eucalyptus woodlands.
Bearded dragons originate from deserts and other dry areas in Australia, with the various species occupying slightly overlapping areas of the landmass. They live in the arid and subtropical woodlands, scrublands, savannas, shore areas, and into the great interior deserts. Their range extends throughout the interior of the eastern states to the eastern half of South Australia and southeastern Northern Territory. They are considered to be semi-arboreal and will quite readily climb and bask at height. This is also linked to dominance behavior and competition for territory/basking areas. They can be found on fallen/broken trees, rocky outcrops and bushes when basking.
Bearded dragons go through a type of hibernation called brumation. Brumation is like hibernation where reptiles go months without eating but they sporadically drink water. Reptiles go dormant in the hottest temperatures, but it differs from brumation during cooler temperatures. When temperatures are extreme, there is a very small range between temperatures that the reptile's bodies can stay active and where their body cannot tolerate the extreme heat and they die. Bearded dragons go through brumation when the temperature goes below 60–70 °F during the night and 75–80 °F during the day for eight to ten hours. When the climate is too hot they will often burrow underground. They will also form more permanent burrows or covered hiding places to use as protection from the climate changes at night and predation.
