The males are much greyer and not so brown on the 
upper side as those of the typical Whitethroats, while the 
edges to the secondaries and greater wing-coverts are of a 
paler, less rufous brown; the female is pale brown on the 
upper side. The measurements of both sexes are larger. 
The two specimens procured by me in Fars also agree with 
this race.

“ Seen for the first time on March 18th, and found again 
quite numerously among the oak-scrub valleys at 4000 feet 
on the north side of the mountains.”—R. B. W.

Blanford obtained the Siberian Chiffchaff only in Baluch¬ 
istan, and it does not appear to have been recorded before 
from North Persia. Mr. Woosnam notes that ChiffchafFs 
were first seen at Resht in the first week of February, when 
there were at least two feet of snow on the ground,” and 
afterwards throughout the whole journey. 
It would seem, therefore, that the bird spends the winter 
in North Persia.
