PROFESSOR J. COSSAR EWART AND DOROTHY MACKENZIE ON 
Fifth Day , Aug. 21. (Figs. 10 and 11.) 
Health and temper both quite good. 
Yellow throat feathers beginning to shed, also the back and side of head (not 
auricular patches) (fig. 10). Outer side of flippers more than half moulted. 
Ate nothing, and did not enter the water, though it sat by the edge of the pool 
for most of the afternoon. 
Sixth Day, Aug. 22. (Fig. 12.) 
Health good, but temper rather doubtful. 
New yellow feathers of the throat showing very distinctly, but rather pale. 
Flippers almost finished moulting ; head shedding all over. Back now moulting 
rapidly. 
Ate one fish, but did not enter the water. 
.Seventh Day, Aug. 23. (Figs. 13 and 14.) 
Health and temper both excellent. 
New yellow feathers of the throat getting brighter. Head moulting rapidly all 
over. Auricular patches shedding and now showing new yellow feathers, still rather 
pale. Green bloom on top of head now clearly noticeable. Back moulting rapidly, 
but in patches — not as symmetrically as the breast. Flippers quite finished. Right 
mandibular sheath shed, leaving the mandible a very pale pink colour. 
Ate nothing, and did not enter the water. 
Eighth Day, Aug. 24. (Fig. 15.) 
Health and temper normal. 
A few old yellow throat feathers still left. Back and auricular patches about 
half moulted. Left mandibular sheath shed. 
Ate nothing, and did not enter the water. 
Ninth Day , Aug. 25. (Fig. 16.) 
Health and temper both excellent. 
Yellow throat feathers almost all gone — new ones much brighter. Auricular 
patches nearly finished, but new feathers still very pale. Back almost finished, still 
a very decided “ruff” on the back of the neck and a few odd feathers at the base 
of the beak. Mandible very pale — a sort of delicate shell-pink colour.* 
Ate nothing, and, though it watched the others swimming, did not join them. 
* The mandible had resumed its normal colour by Sept. 7, and this bird gave its first trumpet-call on the same 
day, viz. twenty-one days from beginning of moult. The voice was very squeaky and high-pitched and occasionally 
threatened to break down, but in a week’s time, by dint of much practice, it had quite recovered.
