ORNITHOLOGICAL NOTES FROM A SOUTH LONDON SUBURB. 
the end of the month, as migrant follows migrant; however, 
owing to the steady increase of building all “around us, this 
interesting movement is yearly becoming less marked. Two or 
three pairs nest regularly in Dulwich “Wood, and the song— 
the earliest note of which is May 2nd—continues up to about 
the third week in June, although the rich warble may some- 
times be heard proceeding from the thick leafage overhead as 
late as the second week in July. 
REED WREN (Non-resident now). 
Up to the year 1895 one or more pairs used te nest in 
Battersea Park, but I have never observed the bird there since. 
Of its appearance in my immediate neighbourhood I| have only 
one note, and that was in 1900, when one sang for one day 
(April 26th) on the island in Dulwich Park. 
A little further afield, until some ten years since, the species 
was fairly plentiful in a willow coppice by the Wandle, near 
Merton, but the trees were then cut down, and the bird appears 
to have forsaken that district. 
SEDGE WARBLER (Non-resident now). 
Of rare occurrence, but in Dulwich Park, previous to 1904, 
when boats were first allowed on the lake, a passing migraat 
was for several consecutive springs to be heard singing for a 
day or two on the island. In 1901—the only year in which 
the species stayed to breed—the song was continued from 
Apnl 20th throughout May and June. It has twice been ob- 
served by the lake-side during the autumn migration, viz. :— 
August 26th, 1898, and September 13th, 1901; but the great 
increase of building all around this formerly attractive park is 
the chief cause of the yearly diminishing visits of all warbler 
migrants, both in spring and autumn. September 17th, 1900, 
a migrant seen in a garden at Lordship Lane. 
COMMON WHITETHROAT (Non-resident now). 
Being essentially a bird of the hedgerow, this is only a 
passing visitor to the suburbs in spring “and autumn. How- 
ever, until quite recently one or more pairs bred on Tooting 
Common, and, I imagine, may still do so on Mitcham Common. 
The usual time of arrival is the third week in April, when the 
bird’s harsh “cha” may be heard in park or garden, the sony
