MEMBERS’ NOTEBOOK 
the nest of the small warbler Burnesia reichenowi. They also 
lay blue eggs, as on May 4, 1911, 1 shot a female of C. cupreus 
with a fully developed light blue egg in the ovary. C. canorus is 
never common in this country and my only dates for it are 
April 2, 1908, and April 10, 1909. Do they breed on their 
southern migration ? 
Then we come to the rarer C. Jacksoni which I may almost 
call a common bird about here, but it lives entirely in forest 
country and only leaves the forest late in the evening, if at all. 
In the evenings, about 6.15, its notes can be heard, but it is 
very difficult to approach, and even if shot the chances are 
greatly in favour of not being able to find it. 
Cercococcyx mechowi has, I fancy, the same crepuscular 
habits, but its notes I am not sure of. Can any member 
say whether either of these birds migrate and, if so, where to ? 
They feed, like other cuckoos, on hairy caterpillars, so one 
would think migration was necessary. 
8. I have lately on two occasions found a dark gray 
flycatcher (? Alseonax) nesting in weaver birds’ nests, but 
unfortunately on neither occasion were there eggs. Is this 
the usual place ?

1. Is Dr. van Someren quite certain that the swallow he 
refers to as breeding plentifully in Chagwe, is H. rustica and 
not H. arcticinata ? I have found many nests of the latter at 
Entebbe, in caves, in sheds, verandahs, and in living rooms 
that were daily occupied, but have never found one of H. rustica, 
nor have I seen this swallow between, roughly, the middle 
of April and the end of September, excepting on two occasions, 
when I obtained a solitary female out of a flock of sand martins, 
Clivicola cincta, near Fort Ternan on May 9, 1901, and a solitary 
male at Kisumu on June 18, 1909. 
2. Regarding Mr. Seth-Smith’s notes on the cuckoos. 
I have found their eggs or young of C. cupreus in the nests of 
Nectarinia kilimensis, Chalcomitra aequatorialis, Motacilla vidua, 
and Prinia mystacea, and once saw a female enter the nest of a 
weaver, H. Jacksoni, but it was promptly evicted by the rightful
