Figure S1. Overview of our experimental flight cage and experimental setup. A) The grid with platform positions is shown in grey. The front locations were situated 3m away from the perch. The grid is shown in more detail in Figure 2. The laptops and gas-relay station used to drive the robofrog setup and speakers were positioned outside the test room, behind the window on the right side of the cage. B,C) The robofrog platform is shown in white, the platforms used as dummy or to broadcast heterospecific frog calls are shown in red. In experiment 1 all platforms were moved around among pre-determined positions using a pseudo-randomizing procedure (A). In experiment 2, four platforms were positioned at the corners of the test grid and onw platform was positioned at the centre. The robofrog platform was randomly switched around (B).
