MIGRATION AND OTHER ORNITHOLOGICAL NOTES. 
suitable waste land at Lowestoft this species did not come 
under observation. 
Greenfinch {Ligurinus chloris). — This species is one of the 
most numerous on the autumn migration, and great numbers 
must pass south along the coast — a fact which, from my own 
observations, applies equally well to the Holderness coast in 
Yorkshire. The flocks appear from the north and disappear 
to the south keeping to the coast line, and not one bird in 
500 settles. The migration begins soon after sunrise and 
practically ceases about 10 a.m. The number passing varies 
on different days, but on days of large migrations, when 
one flock is passing, the next one is frequently in sight 
about 300-400 yards off, and this stream goes on incessantly 
for perhaps an hour, and there are about 30-60 in each flock ; 
such a migration was seen on October 19th. 
The first migrants were noted on September 23rd, and 
from September 30th up to November 8th flocks were seen 
practically every day passing south in varying numbers. 
Passing flocks to the south were noted at Yarmouth on 
November 15th and 21st. I cannot see that the direction of 
the wind has any effect on this coastal migration, but it is 
interesting to note that on October 13th and 14th, with a gale 
from N.E., no movement south of any species was seen, on 
the 15th, however, there were a few flocks passing south 
against a strong wind which varied from S.E. to E. 
On October 6th, 7th, 31st, and November 2nd I saw 
migrating flocks going south and some going north, these 
observations will want corroboration in future autumns, but 
it is suggestive of two different streams of migration. 
In the spring a few flocks were noted going north on April 
8th and 9th and on May 15th. On April 17th some flocks 
were seen going south, a movement which will require further 
confirmation, as will the scarcity of this species on spring 
passage. One bird was taken on a boat 40 miles east of 
Lowestoft on May 11th.
