140 THE SCOTTISH NATURALIST 
on sth April and Noss Head on 13th April. After this much 
passage is reported up to 23rd May, when a few were on Fair Isle. 
Return movement is noted at Noss Head on 2nd August and 
Fair Isle on roth August, and after this date steady movement 
is shown up to 8th October; the notes come from these two 
stations, the Isle of May, Invergowrie, and Alticig (Wigtownshire). 
Piep WactaliL, JJZotacilla alba lugubris—Many returns to 
breeding-places are recorded during March, while from 12th March 
to 16th May considerable movement is noted at Noss Head 
and Fair Isle; a Pied Wagtail is reported at Auskerry on 4th 
April, one at Lerwick on 11th April, and one at Shillay on 1st 
May. Six Pied Wagtails visited Foula on 31st August; Noss 
Head and Lerwick report autumn movement from 2oth August 
to 7th September, and from 17th September to roth October 
there are notes of considerable numbers from our southern stations. 
Single birds are noted at Noss Head on 3rd November, Stranraer 
on 4th December, Cromarty on 24th, Largo on 3oth, and Cullen 
up to 31st December. 
BRITISH TREE-CREEPER, Certhia familiaris britannica.— Single 
birds occurred at the Isle of May on 26th and 27th September and 
21st October (1. 1921, 75), and several probably belonging to 
this race were seen there on 30th September. 
GREAT Titmouse, Parus major.—A Great Tit, no doubt the 
continental P. m. major, appeared at Kergord, Weisdale, Shetland, 
on 2nd May. 
CRESTED TITMOUSE, Parus cristatus.—A Crested Tit, probably 
P. c. scoticus, was observed near Arbroath on 22nd September 
(1. 1920, 178). 
Gotpcrest, Regulus regulus.—From 20th to 31st March 
there are many records of Goldcrests, probably 2. 7. anglorum, 
from Pladda and Little Ross, while what was obviously an 
emigration of 2. 7. regulus is reported from Noss Head, Lerwick, 
Fair Isle, Auskerry, and Shillay from 31st March to 1gth April. 
During September much movement of Goldcrests, doubtiess of 
the British race, is reported from our southern stations and 
lanterns, but a large immigration recorded from Orkney, Shetland, 
Noss Head, and Isle of May, between 29th September and 24th 
October, was evidently referable to the typical form. From toth 
to 13th October numbers of Goldcrests visited the Little Ross 
lantern each night; on 14/r5th October seventeen were killed at the 
Killantringan lantern, and on 24th October many were seen about 
Seggieden. On ist and 3rd November numbers came to the
