608 MIGRATION AND OTHER ORNITHOLOGICAL NOTES. 
Blackbird ( T . merula).- — The only record I have is of 
migrants killed near Yarmouth on the night of October 17th. 
For the same reason as given under Song Thrush, this species 
is not always easy to detect on migration. 
Ring Ouzel (T. torquatus). — One on passage on April 19th. 
Wheatear (S. aenanthe). — The first birds on passage were 
seen on August 14th, and from that date odd birds were noticed 
up to the 26th, when there was a distinct increase in passing 
migrants. Throughout September the numbers noted on passage 
were extremely small, as compared with 1910, and no “ rushes ” 
occurred, though a few were noted each day, except on the 
14th, when there were several, and by the end of the month 
most appeared to have passed through. A single bird was seen 
on October 14th— 19th, and the last on 27th. In the spring 
the first was seen on March 27th, after which date this species 
was seen in twos and threes each day, the individuals often 
halting here a day or so. There was a distinct influx on May 
6th, and again on the 12th. At least one example of the 
Greenland race (S. leucorrhoa ) was seen on April 22nd. 
WhiNCHAT (. Pratincola rubetra). — Four on passage on 
May 9th. 
Redstart (. Ruticilla phcenicurus). — The numbers of this 
species were far less than in the previous autumn migration 
(1910), and there was no “ rush.” The first one was noted on 
August 19th, and single birds on 24th, 26th, and 27th. No 
more were seen until September 23rd, when a few more 
appeared ; these had gone by the 26th. Three at Yarmouth on 
October 5th, and a single bird here on 16th. Not observed on 
spring passage. 
Black Redstart ( R . titys). — Although an equally sharp 
look-out was kept this season, only one bird came under 
observation — viz., on October 8th, at Aldburgh — as compared 
with sixteen the season before. 
Continental Robin ( Erithacus rubecula rubecula). — On 
October 16th two on passage, and some at Yarmouth on the 
19th. One here on 25th, and several on 27th. Not so numerous 
as last year.
