78 Director's Annual Report. 
sufficient to say that sixteen skins of both sexes, adult and imma- 
ture, were secured on Molokai during April, May and June. 
The Ou was met with at all the stations visited in the forest 
area, in a ratio of about one to twenty, as compared with the Ama- 
kihi. Hence it is not, relatively speaking, the abundant species 
its size and song would seem to make it, especially when compared 
with the much smaller and more obscurely colored Chlorvodrepanis. 
The Halawa forest makes an ideal home for this Ieie-loving 
bird, since that region, as has elsewhere been mentioned, is a per- 
fect tangle of this vine. Along the streams patches of wild banana 
are also common, while Olona ( 7ouchardia), another food plant of 
the species, is met with everywhere in suitable places. As Ieie 
has apparently had much to do in the evolution of its peculiar beak, 
the Ou commonly frequents the forests where it is most abundant. 
It is, nevertheless, always to be found in the more dense Ohia for- 
ests, even though the amount of Ieie is small, or wanting entirely. 
In the heavily wooded localities, it feeds through the tops of the 
trees, seldom coming near the ground. At such times there are 
usually several birds in the locality scattered about in scout forma- 
tion. ‘They seem rarely to alight together in the same tree, yet 
they always keep within easy call of each other. The inquiringly 
whistled call note ‘‘Psweet’’ is frequently given, and answered by 
birds thus deployed, especially during cloudy weather. If the call 
is imitated the bird will readily respond a number of times in suc- 
cession, often cautiously approaching the observer to satisfy its 
curiosity. The young birds are much easier decoyed in this way 
than are the more experienced adults. It is not uncommon to 
have the green inconspicuously colored birds answer one from a 
tree near at hand, several minutes before its whereabouts can be 
determined. A number of times during drenching rains, I have 
heard the call note plaintively given, and after protracted search 
have found the bird standing motionless in a very dejected attitude, 
huddled close against a tree trunk, or stowed away in a thick 
bunch of leaves for shelter. 
Of its musical powers much has been written, as it has been 
quite commonly given first place among the singing Drepanididez. 
The song—which, by the way, it rarely gives in its entirety—is 
especially sweet and pleasing, resembling in many respects that of 
the canary. Perhaps the favorite place for delivering its song is
