ORNITHOLOGICAL NOTES FROM A SOUTH LONDON SUBURB. 
between the bridges, and hundreds, too, in St. James’ Park, 
whilst it is noteworthy that at the latter- place some half-dozen 
or so seem to remani all the summer, and presumably breed 
among the reeds on the keeper’s island. 
COMMON GULL. 
This has been recognised—-away from the river—only some 
dozen times, and on most of these occasions in the month of 
December. The species, however, seems to have followed the 
example of the Black-headeds in coming up the river, and one 
or more are not unusually associated with the smaller species. 
LESSER BLACK-BACKED GULL. 
Immature birds have been recognised a good many times, 
although difficult enough to distinguish from the young Herr- 
ine Gull. Mature birds have been noted twice only. 
HERRING GULL. 
Far more often seen than the preceding, both along the 
river and overland. Over the river it is almost common, and 
may sometimes be seen in St. James’ Park, where there are 
some pinioned examples of this Gull. When seen overland, 
the species has almost invariably been observed in March cr 
April, and once or twice in quite large companies. 
“OGCASIONAL” ViISTLEORS: 
These are birds seen either but a few times or at uncer- 
tain intervals. They number 24; 4 are summer migrants, and 
15 appear for the most part in autumn. The summer birds 
have been dealt with already; the others are as follows. 
SPARROW HAWK. 
This has been seen on three occasions; on December Oth, 
1885, one passed close to me in Acre Lane; a second example 
I saw on 12th May, 1883, on Streatham Common; on the third 
occasion one passed over my garden on 15th October, 1909, 
following in the wake of a flock of Chaffinches migrating S.\W.
