Pore radius and pore density
Pore size measured as pore radius was different between the southern species and Brown Kiwi, the latter having smaller pores; pore density in contrast was higher in Brown Kiwi and lowest in Tokoeka. The measurements taken using MicroCT were in accordance with those obtained with SEM, except for Tokoeka. In Tokoeka the pores seemed to thin midway, having a larger outside opening and a broader base (Table 4).
