MIGRATION AND OTHER ORNITHOLOGICAL NOTES.

1st, on which day also an arrival of continental Thrushes 
took place ; and about the same date continental Robins 
arrived at Yarmouth. On the return migration one of the 
continental form was seen on April 13th. Of movements of 
the British race it is hard to be certain, as a fair number, of 
course, are always to be seen. 
Nightingale ( Daulias luscmia ). — One was heard at Fritton 
on April 18th. Our breeding birds were first seen on April 
30th, and they at once settled down in their nesting quarters ; 
no passage birds were noted. 
Common Whitethroat ( Sylvia cinerea ). — A few had arrived 
on passage on September 16th; these at once passed on. 
The first in spring was seen on April 18th, a few were noted 
on passage on April 26th and 27th, and on the 30th there 
was a distinct influx which seemed to populate the neigh- 
bourhood, as they were generally distributed in their haunts 
by May 8th ; on the 25th one pair were feeding young. As 
far as could be noted only a few passage birds were seen, but 
it was difficult to be sure, as several pairs breed on the 
Denes. 
Lesser Whitethroat (A. currucd ). — A few arrived on 
passage on September 19th, on which date they were also 
noted on passage at Orfordness. Several arrived on April 
30th, and although odd ones were seen on subsequent days, 
it is hard to be sure that they were on passage. 
Blackcap (.9. atncapilld ). — A few arrived on passage on 
September 14th with the other “ warblers ” ; one was seen on 
October 31st, on which day there was an increase of Black- 
birds and Thrushes. I have noticed before that odd Black- 
caps appear on the east coast late in the autumn with the 
Turdidse (viz., October 18th and 19th, 1909, Holderness 
coast, Yorks) In the spring this species was not noted on 
passage, but they had arrived in their breeding haunts by 
May 8th.
