466 On the Columba unicincta of Cassin. 
“Their food, at this time of the year at least, consists 
entirely of the berries of a tree called by the natives ‘ Musasa,’ 
avery common tree throughout the Protectorate. I have 
never seen these birds in flocks ; they fly in twos and threes. 
‘‘T moved to another point on the outskirts of the forest, 
where, however, I only camped for one day. Here I found 
a number of Mikindu palms, and again met with C. uni- 
cincta. I asked the natives where they nested and they 
said ‘in the Mikindus,’ which I think very probable: I 
hope to verify the fact soon. I have not heard the note of 
this species yet. 
‘‘The natives say that these birds do not come to the 
shambas to eat the corn, and as very few of the inhabitants 
seem to know them, I think this is most probable, because 
if they ate the crops all the natives would recognise them 
well enough. I have so far found nothing but berries in 
the crops of those that I have examined.” 
My brother has sent home five very good specimens in 
addition to the one which I received from him in 1905 (see 
Bull. B.O.C. vol. xv. p. 75). Four of these, two males and 
two females, are adults, while the fifth, shot in the Budongo 
Forest on Feb. 22, 1907, is an immature male just com- 
mencing to assume the adult plumage. The immature 
plumage of this species has never, I believe, been described, 
so the specimen is of considerable interest. It has, however, 
partially assumed the adult dress; nevertheless, from the 
juvenile feathers that still remain, we may form a good idea 
of the immature stage. 
The general colour is grey, striped and mottled with black, 
chestnut, and white. The top of the head has each feather 
minutely striped with blackish and tipped with rufous brown 
or whitish ; the feathers of the nape and mantle have towards 
the tip a narrow line of blackish fringed with white; the 
rump and upper tail-coverts are grey, fringed with white, the 
lesser wing-coverts becoming black towards the tip and being 
broadly tipped with chestnut-brown ; the primary-coverts are 
the same, but with a narrow fringe of white in addition to 
the chestnut ; the primaries and secondaries are dark blackish
