1. Incorrect Temperature Inside Enclosure

If your bearded dragon is turning black, the first thing to check is the temperature gauge. Most of us are familiar with the fact that bearded dragons are cold blooded animals. The animals categorized as clod blooded can’t regulate their body temperature and depend on external heat sources to keep their bodies warm. So whenever the temperature inside the enclosures drops below the minimum required point, beardies turn black to absorb more heat. Generally, beardies turn black in the morning (when the temperature is usually on the lower side) and retain their original color after 2-3 hours of basking when their body temperatures become normal.

2. Its Breeding Time

If only the beard of your beardie is turning black, he may be looking for a love partner. The beards of male beardies are comparatively darker than female beardies. So when the breeding season arrives (between September and March), male beardies can turn their beards black to attract the females and to show off that I am an appropriate partner. In addition to black beard, they may show some other gestures like head bobbing and arm waving. However, this behavior is visible only when they have reached breeding age (around 1.5 years), and females are around.

3. Feeling Afraid Or Threatened

Since bearded dragons are solitary animals by nature, they get afraid or feel threatened very quickly, even if no actual threat is present. For example, newly adopted beardies can get frightened of their owners and turn their beards black when their owners approach them or try to handle them. In addition, they can get afraid of other larger pets in the house, or even a statue of a prey bird on the wall or a new accessory in their tank is enough to make them feel scared. So changing their body color and turning black (especially beard) is actually their way to appear scarier to the potential threat. And when they feel the threat is over, they return to their original color.

4. Post Brumation Affects

Though brumation (hibernation in the reptile world) is infrequent in captivity, some bearded dragons may still brumate if they get some stimuli required for brumation. Mostly when bearded dragons come out of their hides after brumating, they appear black, as it’s not easy for them to return to routine life and adjust to long light hours (day time) after a long deep sleep. However, beardies gradually adapt to routine life and regain their original color.

5. Feeling Territorial & Aggressive

Beardies are territorial by nature and don’t share their space with others, not even with another member of their own specie. If you are keeping two beardies in the same enclosure, you will frequently see them turning black and fighting. Beardies generally fight to establish dominance, and turning dark is their way of looking aggressive and threatening to the opponent. Even if you have only one bearded dragon, Sometimes, you may observe their beards turning black. It could be because they have noticed some other house lizard or pet approaching their tank, and they turn their beards black to show aggression and warn the visitor to stay away.

6. Stress & Anxiety

If everything else is fine, and you still feel that your bearded friend is turning dark or has turned black, it could be because he is feeling stressed or anxious for any reason. So you should carefully look for the stress factors and try to remove them as early as possible. Your beardie will turn to normal color as soon as the stress factor is removed. Some commonly found stress factors are:

  • The presence of larger pets in the house, which also has access to the place where the beardie’s tank is placed. 
  • Too much noise made by kids, birds or due to other reasons.
  • Improper or rough handling by the owner
  • Handling immediately after feeding food (as bearded dragons prefer to bask after eating).
  • Improper lighting

7. Change In Habitat

Generally, bearded dragons don’t like any change in their environment, and any sudden change in the habitat poses a type of stress. So you can expect your bearded dragon to become anxious and turn black if you have just adopted a new beardie or have entirely changed your beardie’s enclosure. However, once in the new home, beardies generally take some time to get familiar with the new habitat and will return to normal color gradually as they become accustomed to new settings.
