The red-headed lizard commonly observed in Tennessee is the Broad-headed Skink (Plestiodon laticeps). This striking reptile is particularly noted for the vibrant red coloration displayed by adult males during their breeding season.
Identifying the Broad-Headed Skink
While both male and female Broad-headed Skinks can be quite large, their appearance differs significantly, especially during the breeding period.
Adult Males
Adult male Broad-headed Skinks are the namesake of the "red-headed lizard." During the breeding season, typically in spring and early summer, their heads become noticeably large, swollen, and turn a brilliant red or orange-red. Their bodies are generally an olive-brown color. This distinctive head coloration makes them highly conspicuous and easily identifiable.
Adult Females
Adult females are more variable in appearance and typically do not exhibit the prominent red head. Their bodies are usually brownish, often with up to five light or faded stripes running down their back. These stripes can sometimes be less distinct in older females. Juveniles of both sexes also display stripes, which fade as they mature.
Here's a quick comparison:
| Feature | Adult Male Broad-headed Skink | Adult Female Broad-headed Skink |
|---|---|---|
| Head Color | Large, swollen, bright red (breeding season) | Typically brownish, not red |
| Body Color | Olive-brown | Brownish, often with 5 light or faded stripes |
| Size | Can be quite large | Can be quite large |
Habitat and Behavior
Broad-headed Skinks are native to the southeastern United States, including Tennessee. They are primarily arboreal, meaning they spend a significant amount of time in trees, particularly in wooded areas, forests, and swamps. They prefer mature hardwood trees with plenty of crevices and loose bark where they can find shelter and hunt.
Their diet mainly consists of insects and other invertebrates, such as:
- Crickets
- Grasshoppers
- Beetles
- Spiders
- Caterpillars
They are known for their speed and agility, making them effective predators. When threatened, they will often quickly dart into tree crevices or under bark to escape.
Broad-Headed Skinks in Tennessee
In Tennessee, these lizards are a common sight in suitable habitats across the state. They play an important role in their ecosystem by helping to control insect populations. Observing a male Broad-headed Skink with its striking red head is a unique experience for nature enthusiasts in the state.
