196 A LIST OF THE BIRDS OF PEGU. 
assume a distinct plumage for a short time, and then the change 
towards adult plumage rapidly progresses. Some interesting 
remarks on the allied Australian Cuckoos will be found in 
P. Z. 8., 1865, p. 460, by Mr. Edward P. Ramsay. 
128.—Coccystes jacobinus, Bodd. (212.) 
Confined to Thyetmyo and its neighbourhood where it is 
common. 
129.—Coccystes coromandus, Lin. (2138.) 
Distributed over the whole province, and fairly common. 
130.—Eudynamis malayana, Cab. & Hein. (218.) 
Common all over Pegu from February to June. I have 
procured nestling birds in May. 
131.—Rhopodytes tristis, Less. (215.) 
A very common bird in all parts of the provinee. Consider- 
ing however what a remarkable tail it has, it is wonderful how 
seldom it is seen. It glides very gracefully from branch to 
branch, concealing itself admirably. 
132.—Centrococcyx intermedius, Hume. (217 quat.) 
Birds from all parts of the province are similar. It is very 
common, except in the thicker forests, where I have not 
observed it. 
133.—Centrococcyx bengalensis, Gm. (218.) 
Extremely abundant in all the lower open parts of the 
country. It is not a forest bird, but rather one of grass land, 
especially where swampy. The length of the upper tail-coverts 
in this bird is, I think, entirely dependent on age and not in 
any way connected with season or sex. 
The young birds in first plumage are clothed in the adult 
winter plumage ;* hence it happens that .in September and 
October birds in both stages of plumage are found together. 
* If we are to gather from this that Mr. Oates has ascertained that the white 
shafted plumage is the normal adult winter plumage, the fact is important. 
Hitherto the question since I touched upon it, S. F., III, 84, and mentioned for the 
first time on Mr. Simson’s authority, that this stage of plumage was seasonal, the 
matter has been sub judice. I have preswmed that the brown white shafted plumage 
was that of the cold weather, because the great majority of my specimens, killed 
between the 15th November and 15th March, were in this stage; several killed between 
15th March and the end of April in an intermediate stage, and the great majority 
killed between 1st May and 1st November in the black stage. But then I have 
perfectly black birds killed at the end of November and in January, and brown birds 
killed in May and June. But I am not sure that these dates, which are Mandelli’s, 
are reliable, and certainly every specimen of our own collecting, or of which the 
dates are certainly reliable, confirm Mr. Oates’ present statement,—ED., §. F.
