Fig. 8. Net vertical efficiency (mean ± s.e.m.) for 5 grey-headed albatross (GHA, open circles and solid line) and 11 black-browed albatross (BBA, filled diamonds and broken line), when walking on the treadmill with at different percent inclines ranging between 2–12%). Regression equation for GHA: y=–3.29x+44.04, R²=0.84, and for BBA: y=–0.69x+22.65, R²=0.35. The GHA data point at 9% represents only one animal; the others were unable to perform at this level.
