I investigated the methods and techniques used to study the movements and ecology of hylid frogs. A review of associated literature was conducted to consolidate the variety of techniques into a single, stand-alone document for researchers in the field. In order to test novel radio transmitter attachment designs, a series of controlled experiments were conducted, incorporating behavioral, morphometric and hematological parameters. The top design was then applied in a field setting to the gliding leaf frog (Agalychnis spurrelli) and veined tree frog (Phrynohyas venulosa). I determined that my method was not suitable for the gliding leaf frog, but suitable for studies of the veined tree frog. I observed partial migrations away from the breeding pond by the veined tree frog. Data on the temporal activity patterns did not support the veined tree frog being strictly nocturnal species.
