From: Invasive brown treesnakes (Boiga irregularis) move short distances and have small activity areas in a high prey environment

Figure 4

Examples of large (18.53 ha3) and small (3.06 ha3) 3D activity volumes from two male brown treesnakes (Boiga irregularis) with 1820 mm snout-vent length (SVL) (A, blue 75% isopleths surrounded by grey 95% isopleths) and a 982 mm SVL (B, green 75% isopleths surrounded by grey 95% isopleths). Two plots are shown in each panel, one from the lateral perspective as if you were standing on the ground (height = 0) and the other from approximately 45° angle from above. Note how both 3D activity volumes approximate a series of oblate spheroid shapes.
