Mr. M. J. Nicoll— Contributions 
migration. It makes its appearance during the last days 
of March. I have only one record for the autumn—an 
adult female, which I shot near Giza on August 21st, 1907. 
I believe this species to have but one moult in the year, 
namely, in autumn.

The Blackcap arrives in September, and is one of the few 
Warblers that spend the winter in the Zoological Gardens. 
I have frequently heard it singing from November onwards 
till April, when it takes its departure. This bird moults 
in autumn, and undoubtedly some individuals moult 
again completely in spring; I fancy, however, that these 
are young birds of the previous year. The same remarks 
as regards moult apply to the Lesser Whitethroat ( Sylvia 
curruca).

I have once or twice seen Garden-Warblers in the Giza 
Zoological Gardens during the autumn migration, but have 
no specimens from Egypt.

The first Bufous Warblers make their appearance in 
March. The earliest date on which I have seen one is on 
the 17th, but the main body do not arrive till April, from 
which month onward, until they take their departure in 
September, they are abundant.

Phyllopneuste bonellii Shelley, p. 101. 
Bonelli's Warbler is a regular visitor in large numbers 
during the spring migration, and again in much smaller 
numbers during the autumn movement southward.
