MIGRATION OF BIRDS 
231 
breeds in Central Europe, where it is resident in the summer 
months from April to September. Fair numbers come here 
in November and remain till March. 
19. The Lessee Reed Waeblee (Acrocephalus strepherus) 
as a breeding bird is found over Europe generally, between 
April and September. At the end of the latter month they 
migrate, some arriving in this country in October, but most 
make their appearance in November and leave again in April. 
20. The Marsh Warbler (Acrocephalus palustris) breeds 
in England and Europe generally, not including Sweden and 
Norway. Large numbers come here in November, and are 
to be found along rivers and swamps up to April ; the latest 
date that I have recorded is May 25. 
21. The Sedge Warbler (Acrocephalus phragmitis), as a 
breeding bird occurs over Europe generally, between April 
and September. It is a very common migrant, arriving in 
September and remaining till May. 
22. The Pallid Warbler (Hypolais pallida) breeds in 
South Europe and South-West Asia, and winters in East Africa, 
arriving here in November and going north in March. 
23. The Barred Warbler (Sylvia nisora) is found in 
Germany, and South Sweden, North Italy, south to Russia 
and Turkestan. It has rarely been taken in East Africa, 
December to February. 
24. The Garden Warbler ( Sylvia hortensis) breeds in 
Europe generally ; the southward movement commences in 
September and continues till October. During last autumn 
the first arrivals in this country turned up in September ; 
fresh arrivals appeared in increasing numbers till November. 
Dozens remained in my garden till January, after which they 
gradually decreased, the last lot being seen on April 5, in this 
district. Later on, I came across a few birds at Kisumu, in May. 
25. The Blackcap Warbler (Sylvia atricapilla) breeds 
in Europe generally, east to Asia Minor, west to Cape Verde, 
and also in North Africa. They begin to leave their breeding 
grounds in September, and arrive here at the latter part of 
that month, and particularly in October. They went north 
in February and March. At one time during last winter these 
birds were even more numerous than the Garden Warblers.
