108 Mr. B. Alexander — Expedition 



All the adults, except one female in full moult, clearly 

 sliow the bastard primary; in the immature bird this feather 

 is distinctly longer than in the adult. 



Immature male in first plumage. General colour above 

 pale rufous-buff; most of the feathers of the crown, back, 

 and wing-coverts have a brownish-black spot at their 

 extremities, otherwise the plumage of the upper parts is 

 much like that of the adults ; the ear-coverts are dull 

 rufous-brown, and the chest is distinctly washed with rufous- 

 buff. 



6. Strepsilas interpres. 



7. PuFFiNus MARI.E Alexander (see above, p. 92). 



^ E,aza and Branca may be looked upon as the chief 

 habitat of this species. Before landing on Raza we saw a 

 large flock in a wedge-shaped formation sleeping on the 

 water. They frequent chiefly the hollows in the cliffs, 

 but we found some on the higher ground in holes made by 

 the birds themselves underneath large boulders, where the 

 entrances were strewn with small stones and flakes of rock, 

 evidently brought there by the birds, since the soil is of a 

 fine nature. 



These Shearwaters appear to prey upon smaller birds, for 

 in many instances the vicinity of their holes was strewn 

 with bones and feathers. While on Brava, we constantly 

 heard this bird at night among the hills ; its weird cry, 

 only enhanced by the silence, is like the whistling cry of the 

 Wigeon. When fishermen land on Baza, they capture many 

 of these birds for eating purposes, sometimes taking away 

 almost a boat-load to their homes. 

 Twelve specimens were obtained. 



8. Ardea garzetta. 



Observed, but there is no breeding-station on the island. 



9. Phalacrocorax lucidus. 



10. SuLA fiber. 



Five clutches of eggs obtained.
