Florida's Iguanas Turn Fiery Orange for Winter Mating
25 Dec
Summary
- Green iguanas in South Florida turn orange during winter breeding season.
- Hormonal changes cause adult males to develop vibrant, reddish tones.
- This seasonal color shift helps males attract mates and deter rivals.
In winter, South Florida residents may observe green iguanas displaying striking orange and reddish colors. Native to Central and South America, these invasive reptiles were introduced in the mid-1900s and have since become a common nuisance, damaging vegetation and disrupting local ecosystems. The vibrant coloration appears in adult males during the breeding season, which spans from late fall to early spring.
These color changes are attributed to hormonal fluctuations that increase pigmentation, helping males attract mates and intimidate rivals. This phenomenon is not unique to iguanas, as many reptiles exhibit seasonal appearance shifts. However, the vividness of the South Florida iguanas' transformation is particularly notable.
While sexually mature males undergo this striking change, females and younger iguanas typically retain their green or brown coloration. The intensity of the orange hue can vary based on the individual iguana's age, health, and hormone levels, underscoring their deep establishment within Florida's habitat.
