Bull er sagt über den Fundort und das Verhältniss von ji. haasti zu oweni 

 (Tr.N.Zeal. Inst. 1896 XXIX, 204): „I elicited from my coUector one very singular fact: 

 on the western watershed of the Heaphy Range, where, as a rule, Apteryx haasti 

 alone is found, the loose ground is inhabited by a very large earthworm, on which this 

 species principally feeds. On the eastern side, where the Grey Kiwi (Apteryx oweni) 

 abounds, the large earthworm is not to be found, its place being supplied by a very 

 small earthworm, on which this species seems exclusively to subsist. The summit of the 

 main ränge — say a tract about a mile in width — distinctly divides the ränge of one 

 species from that of the other. May not this remarkable difference in the natural food- 

 supply have influenced the development of these two closely-allied species in divergent lines 

 — the one being now distinguished by its massive skeleton and robust proportions, and the 

 other by its slender structure and generally feeble development? The general style of the 

 plumage is the same in both, it being easy, in a sufficient series of specimens, to trace 

 a gradation from the dappled-brown plumage of Apteryx haasti to the dappled-grey 

 plumage of Apteryx oweni."
