A Review of the Frogs of the Hyla bistincta Group

** "A Review of the Frogs of the Hyla bistincta Group" by William Edward Duellman is a scientific study from the early 1960s that looks closely at a specific group of frogs, the Hyla bistincta group, mainly found in the mountains of Middle America. The book uses observations from nature and careful study of the frogs' bodies to classify them. Duellman gives detailed descriptions of five different types of these frogs, explaining what they look like, where they live, and how they reproduce. The book points out what makes each species unique, like their colors and calls. It also explores how these frogs are related to each other, highlighting how they've changed to live in water and the environments where they do well. Through studying many examples and comparing information, Duellman adds important details to how we understand these tree frogs and where they fit in with other amphibians. **
