About Buergeria robusta (Boulenger, 1909)
Buergeria robusta is a species of medium to large-sized treefrog. Individuals have stocky bodies: males reach 4–5 cm (1.6–2.0 in) in snout-vent length, while females reach 7–8 cm (2.8–3.1 in). The skin on their dorsum is smooth, and their body color changes to match their environment, ranging from brown or gray to greenish, and even yellow. Their breeding season runs from February to September; during this time, males sit on top of rocks and call to attract mates. Females deposit eggs directly into water, and do not build foam nests for their eggs. This species is endemic to Taiwan, where it is called the brown tree frog. It is a common, widespread species found at low to medium altitudes, and lives primarily near creeks or streams. It is locally threatened by habitat loss, and is also collected for human consumption. The genetic distribution of Buergeria robusta matches Taiwan's topography closely, with populations on the eastern and western sides of the Central Mountain Range showing prominent genetic divergence.
