 Phalacrocorax colensoi, Buller, B. N. Zeal. 2ud ed. ii. p. IGO (1888) 



[part : The Bluff, Southland, New Zealand]. 



Adult in full breeding-plumage. Much like P. onslowi in plumage, 

 but the neck is somewhat greener ; a well-developed crest, white 

 alar bar, and dorsal patch are present, but there is no trace of nasal 

 wattles, the lores being thinly feathered; behind and above the 

 eye a thin patch of white hair-like feathers. Tail composed of 12 

 feathers. Eyelid light blue ; naked skin on lores and sides of face 

 very dark blue ; a row of small red warts between the culmen and 

 the eye ; naked skin at base of lower mandible and gular pouch 

 arterial red. Total length about 29 inches, culmen from feathers on 

 forehead to tip 2-4, depth to cutting-edge 0-35, wing 11"6-11'7, tail 

 5'l-5"3, tarsus 2-8, outermost toe and claw 4-3. 



Although the bill is nearly as long as that of P. carunculatus, it 

 is not nearly so stout. 



Adult in non-hreeding plumage. Similar to the above, but without 

 a crest. 



Immature. Very similar to the immature of P. onslowi. In a 

 bird apparently changing to the adult plumage the white, alar bar 

 is strongly developed.

Adult in full hreeding-plumage. Very similar in general appear- 

 ance to P. onsloivi, having a well-developed crest, but as in P. steivarti 

 the nasal wattles are entirely absent. The alar bar is generally less 

 defined and there is never any trace of the white dorsal patch ; the 

 white band down the fore-neck, which unites the throat and chest, 

 is much narrower, the dark sides of the neck being only narrowly 

 divided from one another. Tail composed of 12 feathers. Total 

 length about 25 inches, culmen from feathers on forehead to tip 

 2-05, depth to cutting-edge 0'25, wing 10-6-10-9, tail 5, tarsus 2-35, 

 outermost toe and claw 3*07. 



An immature bird has the white alar bars entirely wanting.
