When measurements of A. k. stronachi from the two studies were pooled, the Tanzanian race (ti=21 individuals) was indeed found to be significantly larger than the nominate race (/7=3: Stuart & Collar 1985), in terms of wing length (Mann-Whitney U321 = , p=) and tail length (Mann-Whitney U221 = , p=), but not tarsus length (Table 1). Whilst tail lengths of canopy-dwelling Apalis species were, on average, 10% longer than their wing lengths (mean ratio of tail : wing length = :1; 77=10 species), the converse was true of species associated with lower vegetation layers (mean ratio = :1, 77=5) (Mann-Whitney U5J0 = , p=).
