Behavioral Tracking for Bearded Dragon
Pogona vitticeps
Reptilian sleep, social cognition, and visual behavior in Pogona vitticeps. ConductVision delivers automated tracking and quantitative parameter extraction across the full assay catalog below.
Why Bearded Dragon in Behavioral Research
The Australian bearded dragon is a leading reptile model and the species in which REM-like sleep was first demonstrated outside mammals and birds. Its rich visual and social behaviors, plus tractable handling, make it valuable for comparative neuroscience and sleep research.

What We Measure in Bearded Dragon
Validated assays with quantitative parameter tracking for Pogona vitticeps.
Bearded dragons exhibit two alternating sleep states reminiscent of mammalian SWS and REM, with rhythmic eye movements and rapid forebrain oscillations. EEG and behavioral state quantification underpin sleep-evolution research.
| Parameter | Unit | Description |
|---|---|---|
| SWS-like duration | min/night | Slow-wave state time |
| REM-like duration | min/night | Rapid forebrain state |
| Cycle period | min | SWS↔REM oscillation |
| Rapid eye movements | events/min | During REM-like state |

Bearded dragons learn by observation, opening sliding doors after watching demonstrators. Trials to criterion and side-bias matching quantify social learning in a reptile.
| Parameter | Unit | Description |
|---|---|---|
| Trials to criterion | count | Acquisition speed |
| Demonstrator-side matching | % | Imitation fidelity |
| Latency to first attempt | s | Engagement |
| Success rate | % | Task completion |

Bearded dragons signal dominance and submission with stereotyped head bobs and arm waves. Display rate and posture index agonistic and reproductive states.
| Parameter | Unit | Description |
|---|---|---|
| Head bobs | count/min | Dominance signaling |
| Arm waves | count/min | Submission signaling |
| Beard darkening | index | Threat coloration |
| Dyadic outcome | win/lose | Encounter resolution |

Bearded dragons alternate between basking and exploration, with thermoregulatory cycles dominating activity. Time in basking, distance traveled, and substrate temperature index normal behavior.
| Parameter | Unit | Description |
|---|---|---|
| Basking time | min/h | Time at heat lamp |
| Distance traveled | m | Locomotor activity |
| Body temperature (cloacal) | °C | Thermoregulatory target |
| Substrate occupancy | % | Hot vs cool side |

Pogona darkens its beard in threat and lightens dorsal coloration when basking. Color changes index motivational and thermoregulatory state.
| Parameter | Unit | Description |
|---|---|---|
| Beard darkness score | index | Threat coloration |
| Dorsal lightness | index | Thermoregulatory state |
| Color-change latency | s | Onset after stimulus |
| Display duration | s | Persistence |
