PLUMAGE. 
As usual most of the notes regarding plumage refer 
to albinisms: two Jackdaws seen at Dunkeld had pure white 
heads and white markings on their wings, a female House 
Sparrow at Collessie had a white head “dirty on the top, 
pure white on the nape,” and a Blackbird at Lerwick had a 
white patch on the right wing. An interesting point about 
the last is that it is recorded on various dates from January 
to May, and again in October and November; from this 
it would seem that it is a winter visitor to Shetland. A 
very light-coloured drake Mallard frequented Duns Lake 
in December ; “ where the normally coloured ones are grey 
he looks quite white. The head looks nearly black, the 
green is so dark, and the bill is rich orange not greenish 
yellow. He is conspicuous both on the water and on the 
wing.” A pure white Sand-martin was seen by Colonel 
Drummond Hay at Seggieden (Perth) on 30th August. He 
says: “I... saw the albino quite close, there was no doubt 
ipmwase a oand-martin, | watched it forssome time, >) It 
was pure white all over, and was with a party of from 
200 to 300 other Sand-martins. Colonel Drummond Hay 
also describes the plumage of a young bird of this species 
which came into his house on 17th August and was caught 
and examined before it was released; the ground colour was 
pale cream, the dark markings being represented by shades
