Fig. 5. (A) Stride length (Ls) (mean ± s.e.m.) achieved
by five grey-headed albatross (GHA) and 11 black-browed albatross (BBA), when
walking on the treadmill at maximal speed with 0% incline (P=0.497).
(B) Mean (± s.e.m.) Ls, when walking on the
treadmill at a speed of 0.6 km h–1 at maximal % incline.
Significant differences can be seen between species (P=0.000). There
is also a significant difference (P=0.003) in both BBA and GHA
between Ls when performing on the flat (A) and on the
incline (B).
