“…Often a wind tunnel is substituted for a water flume so that flying animals can be recorded while remaining in more‐or‐less the same position. The majority of recent DPIV applications to terrestrial systems have focused primarily on the patterns of air movement generated during animal flight in a variety of taxa, from moths to birds (e.g., Tobalske, ; Mountcastle and Daniel, ; Altshuler et al, ; Hedenström et al, ; Spedding and Hedenström, ; Tobalske et al, ).…”

“…Since the PIV technique necessarily measures velocities by correlation peaks in particle displacement over a known laser pulse interval, the resolution of the interrogation regions twice acts as a low-pass filter on the flows it is measuring: the first because of the assumption that the displacement within the pulse interval is a true reflection of the distance moved (this can only ever be an underestimate of the true distance moved), and the second by spatial smoothing (c.f. Spedding and Hedenström 2009). Because of the short time interval between pulses, the second effect is likely to play a greater role, and becomes critical when assessing, say, the momentum contained within a vortex ring in the wake, because momentum is calculated using the product of vortex core diameter and flow velocities tangential to the circumference.…”

“…Flow visualisation is an alternative technique that allows forces to be inferred through examining the structure of the wake (e.g. [3], [4], [5]) this approach aims to reduce interference between the subject and measurement apparatus, allowing the experimenter to capture more natural kinematics.…”
