- The page saysa knack for staying upright when the ground drops away
- The source says
guinea fowl are quite successful in maintaining dynamic stability, as they stumbled only once (without falling) in the 19 unexpected perturbations
Note: tagline - The page saysResearchers camouflaged a drop in the running surface so the birds had no visual cue about the drop.
- The source says
we perturb the running of guinea fowl with an unexpected drop in substrate height (DeltaH). The drop is camouflaged to remove any visual cue about the upcoming change in terrain

- The source says
they stumbled only once (without falling) in the 19 unexpected perturbations
- The page saysWhen the drop was in plain sight, they stumbled in 4 of 20 trials and fell twice.
