Three types of obstacles used to collect accelerometer (behavioral) and magnetometer (compass) data designed to encourage ‘mousing-like’ leaps. a Square enclosure (10 × 10 × 1 m) made of cut pine planks used to collect foraging and ‘mousing-like’ leap behavior with Fox2. b Vertical wall obstacle (~1 m tall) made of pine boards and plastic mesh that stretched across the entire outdoor arena used to collect ‘mousing-like’ leap behavior with Fox1. The smaller wooden barrier placed ~1 m beyond the large vertical wall forced the fox to rapidly decelerate after jumping over the initial wall, similar to natural mousing jumps when a fox will leap through the air and land on top of its prey. c Four-corridor obstacle with ~1-m-square ‘food reward area.’ A food reward was placed in the center of the obstacle and the fox would walk down one of the four corridors then leap over a ~1-m-tall mesh gate to obtain the food reward. Each corridor was aligned along the cardinal compass directions (magnetic N, E, S, and W). d Overhead schematic of four-corridor obstacle. Solid line leading into the East corridor represents the fox’s path toward the food reward area, and dotted line represents the fox’s leap, in this case heading magnetic west, over the mesh gate to obtain the reward
