Green Tree Frogs (Hyla cinerea), also known as American Green Tree Frogs, are charismatic amphibians native to the southeastern United States. One of their most captivating features is their vibrant green coloration, which helps them blend seamlessly into the lush foliage of their arboreal habitats. Interestingly, these frogs have the ability to change color slightly based on environmental factors such as temperature, humidity, and light intensity. They may appear brighter green during periods of high humidity or after rain, and their color can darken to a duller shade in drier conditions. This color-changing ability not only aids in camouflage but also serves as a form of thermoregulation, allowing them to absorb or reflect sunlight as needed to maintain optimal body temperature.

Green Tree Frogs are renowned for their melodious vocalizations, particularly during the breeding season. Male frogs produce a distinctive call that sounds like a series of short, high-pitched "quonk" notes repeated at intervals. These calls serve multiple purposes, including attracting females for mating and establishing territorial boundaries against rival males. The intensity and frequency of these calls can vary depending on factors such as ambient temperature and the presence of competing males. This vocal prowess contributes to their social dynamics and reproductive success within their habitat. In addition to their striking appearance and vocal talents, Green Tree Frogs are arboreal specialists, spending much of their time perched on vegetation near water bodies where they hunt for small insects and other invertebrates. Their agile climbing abilities, aided by adhesive toe pads, enable them to navigate dense foliage and efficiently capture prey, showcasing their adaptation to life in the treetops.
