ADELIE PENGUIN—LEVICK. 67 
place in different directions as the bird shifts its position, the nest assumes the 
picturesque appearance of a bright green flower, as the penguin adds its decorative 
offerings petal by petal. ° 
Even after the chicks have come, the nest is kept clean, as they lie with their 
heads towards the centre and their little sterns protruding. 
As soon as feeding began again, the whole appearance of the rookery changed, and 
from green, its colour was changed to brick-red, owing to the colouring-matter derived 
from the HKuphausia on which the Adeélies entirely subsisted. 
The manner in which the incubating and nursing duties are shared, in order to give 
each of the birds a periodical chance to go and feed, has been well described by former 
writers. I kept a watch on a good many couples, and their arrangements seemed to 
73 
tally very closely with the following “ watch bill” kindly kept for me by Mr. Priestley. 
As the nest in question was close to the meteorological screen, Mr. Priestley 
passed it several times during the day as well as in the night, on his way to take his 
observations ; and from his notes, so obtained, I made out the following time-table. 
Only one egg was seen. 
Nov. 14th—Ege laid. Hen sitting. 
,  27th—A cock seen to join the hen for the first time since the 14th. He 
took her place on the nest. This was the first day on which any 
red guano was seen about the nest. 
Dec. 10th.—The hen returned between 8 p.m. and 10 p.m., having been absent 
since Nov. 27th. Fresh red guano: the first for many days. 
14th.—The cock relieved the hen between 8 a.m. and 10 am. Between 
6 p.m. and 8 p.m. the chick was hatched, the hen remaining on
