Fig 6. Acceleration in defending trajectories.

Fig 6

The green cross markers show the mean acceleration of defending bird trajectories that approached the feeder from a specific perch (n = 16 trajectories at t d = 0 and n = 15 at t d = 0.11 seconds) while pink diamond markers show mean acceleration of all other defending bird trajectories (n = 17 at t d = 0, n = 15 at 0.09 seconds, and n = 11 at 0.20 seconds). The black asterisk markers are the mean acceleration of all defending trajectories (n = 32 at t d = 0, n = 30 at 0.09 seconds, and n = 26 at 0.20 seconds). Error bars show the standard error about the mean for the perch and nonperch data only.
