56 Mr. Hugli Wliistler on the 



are gone by the middle of September. It is interesting 

 to note that on August 24 there were numbers about the 

 tonga-road from Chakwal to Mandra which were clearly 

 migrating birds, as the locality is unsuited to them ; during 

 the many other journeys I made over that road I saw 

 the species but seldom. This Golden Oriole breeds freely 

 in the Rak and the gardens of the Salt Range from the 

 middle of April to the middle of July. The percentage 

 of pairs in which both birds are in full plumage appears to 

 be very small. 



[Mr, Whistler's series of Orioles is very interesting, and 

 shows the different plumages at different ages; 781 and 743 

 are fully adult, 745 and 728 have the dark part of the tail 

 yellowish olive-green, which extends to the outer webs of all 

 the feathers, and there is no black on the wing-coverts ; abore 

 both are coloured alike and both are streaked with brownish 

 black below. However, 728 has more yellow in the plumage 

 of the underparts than the other (whose throat is greyish 

 white), and its bill is dull claret where the other is only 

 tinged with this colour, while the tips of the primary- 

 coverts make much more of a yellovv wing-spot, rather more 

 yellow on the inner webs of the wing, and the lores and 

 orbicular are more marked, so that I am inclined to regard 

 this bird as 24 months old and the greyer duller bird as 

 12 months old. If this is so, then 768 must be 36 months 

 old with primaries blacker, loral mark and wing-coverts 

 mixed with black, the dark portions of the tail blacker and 

 not reaching the tip of the outer web, while the yellow on the 

 inner web is larger and the upper and under parts of rather 

 a brighter hue. Of the females, 771, 748, 769 have grey 

 throats and their tails are similar, but two of them are 

 yellower underneath than the third ; they are similar above, 

 but one has a slight indication of black on the median coverts. 

 1 regard these as all probably being 12 months old, though 

 it is difficult to be sure ; 771 was paired with a fully adult 

 male, and 769 was paired with 768, which I have regarded as 

 36 months old. 739 may be of this age also; its wings and 

 tail ^re like the other three, but it has the throat yellow
