I interviewed the " Rock-hoppers " of four rookeries, and 

 observed that some of their notes were soft and low, as a 

 prelude to a high key being struck. While the voice of 

 the adult is generally guttural, the young bird utters a single 

 piping note. Ou Murray Island the rookery contained 

 some 160 birds, one half sitting upon two eggs, the mates 

 in most cases standing alongside the sitters (January 2nd). 

 On dissection it was proved that males took part in incu- 

 bation. With the exception of two nests (in which the 

 nestlings were very young), most, if not all, contained eggs 

 with much-developed chicks, two to each clutch. The eggs 

 agree with the description of those of the Rock-hopper of 

 New Zealand in Buller's 'Birds/ The average measure- 

 ments were 2*65 x 235 inches. The nests were composed of 

 collected shingle, and apparently slightly raised, many being 

 plastered in a rough way. Their diameter was approximately 

 7 inches. While taking photographs of these Penguins, I 

 found them to be fairly good sitters, and I even tried means 

 to get some badly positioned birds into better places. 



My first acquaintance with the young was on January 2nd, 

 when they were but a few hours old. 



Stage a. Down light black above; ventral surface white 

 below ; head and throat intense black ; flanks greyish ; wings 

 grey ; bill — proximal end black, distal end yellowish white. 

 There is a marked ridge along the abdomen. 



On February the 8th, in Accessible Bay, two further 

 stages were observed in the rookery. Although they had 

 not the agility to hop into view and out of sight, like their 

 parents, they moved by hopping, displaying care. On my 

 appearance in the rookery, seven or eight of the young in 

 front of me huddled together, and one old bird seemed to
