196 ANNALS OF SCOTTISH NATURAL HISTORY 



CoRVus MONKDULA (Jackdaw). — At Caldwell (Renfrew) nests in 

 Spruce Firs visited on 3rd May, were very large and flat, roofed 

 with sticks leaving only a round hole to admit bird. Two 

 nests had six and two four eggs. One of the clutches of six 

 was fresh laid, the other in a nest quite open to the sky was 

 highly incubated. There were great numbers at Spiggie 

 (Shetland) on loth April, and many arrived in Fair Isle on 15th 



(P- 75)- 

 C. CORAX (Raven). — Has young in Perthshire 15th April, and 

 young flying at Arisaig 14th May. 



C. CORONE (Carrion-Crow). — Added to the Fair Isle avifauna this 

 year, one being seen for some time in autumn (p. 75). 



C. coRNix (Hooded-Crow). — One in the Fair Isle in September 

 showing a tendency to albinism (p. 75). Eggs hatching at 

 Arisaig 14th ISIay. A lot at Swordale on 22nd. 



C. FRUGiLEGUS (Rook). — In 1904 a pair built their nest in a 

 chimney-can at Beith. The nest was pulled out and another 

 was started, but the shooting of one of the birds put an end to 

 the experiment for that year (A.S.N.H., 1905, p. 209). In 

 1907 another attempt was made, but the birds themselves 

 changed their plans and carried the sticks they had gathered 

 to a tree near by. Was one of the 1907 birds the survivor of 

 the 1904 experiment? — Mr. Craig asks. Builds at Kirkliston 

 26th February, Edinburgh 28 th. Lays at Kirkliston 23 rd 

 March. On 6th April at Lugton (Renfrew) one nest with two 

 eggs, three with three each, seven with four, twelve with five, 

 two with six, one with young. Great numbers at extreme 

 northern localities (Pentland, Lerwick, Spiggie) 8th to loth 

 April. At Swordale 24th August, large flocks ; Lerwick, 29th 

 October, flocks ; Swordale, 6th December, enormous flocks with 

 starlings. One pale grey at Gilston (Fife) on 24th May.

 west in snow at Glasgow ; 14th sings Kirkliston, i8th Glasgow ; 

 nesting in the Outer Hebrides seven miles from the nearest 

 cultivated land (A.S.N.H., 1907, p. 210). A mimic of the 

 notes of the Dunlin, Ringed Plover, Oyster-catcher, and Red- 

 shank {I.e.). Last in song Kirkliston, 15th July, and resumes 

 song there loth September. Seven in Mull on nth October 

 (wind S.E.). Marked scarcity there on autumn migration.
