to 17th April movement is recorded steadily from Fair Isle and 
Noss Head, and there were a few Blackbirds at Little Ross on 15th 
April (1. 1920, 147). Autumn arrivals are noted on the Isle of 
May on 2g9th and 30th September and 2nd October. A large 
immigration is recorded from our northern and eastern stations 
from 6th October to 6th November, these being evidently conti- 
nental birds arriving on our shores. Pladda and Little Ross record 
a good many too on 1oth, 12/13th, and 13/14th October; eighty 
were killed at Killantringan light on 14/15th October; and Pladda 
and Little Ross again report movement on 3rd and 4th November 
and rgth to 28th November, while one was killed at the last-named 
lantern on 7th December. 
WHEATEAR, Cinanthe wnanthe enanthe.— Several Wheatears 
were killed at the Little Ross lantern on 20/21st March (1. 1920, 
147); one at Pladda next night; a male was seen at Noss Head 
on 23rd March, and many at Shillay (Monachs) on 27th. After 
this, constant movement is noted throughout April and up to 15th 
May, the largest numbers recorded being between 14th and 23rd 
April. By the 2nd August autumn movement was evident, and 
a steady stream of notes come in up to 7th October; in no case 
are large numbers reported, just small, constant migration. Last 
seen, Auskerry lantern, Noss Head, and Pladda 13th October, 
Whalsay Skerries lantern, and near Melrose next day, and Largo 
Bay 27th October. Possibly some of the above should be referred 
to the next subspecies.

birds are recorded from Monifieth Bay on 2nd May, Noss Head 
next day, and three at the latter station on 4th May. From 27th
