Mr. J. H. Stenhouse : 
[Ibis, 
(Enanthe oe. cenanthe. 1 $ . 
Passes on migration. First seen 22 March, 1919, and 
2 April, 1920 ; one struck the Europa lantern 14 April. In 
autumn many were seen at Gibraltar 17 October ; they had 
all passed on next day. Two seen near Tarifa on 2 May 
were probably the Greenland form (GE. oe. leucorrhoa), but no 
specimen was obtained. 
(Enanthe h. hispanica. Black-eared form. 1 d ; 2 $ . 
First seen 22 March. 
Black-throated form. 1 d ; 2 $ . 
First observed 12 March. Both forms bred on the Queen 
of Spain’s Chair and also on some rough ground at El Cobre 
behind Algeeiras. In 1919 their numbers were about equal. 
In 1920 the black-throated were in the proportion of about 
4 to 1 of the black-eared. Autumn migration began early ; 
birds of the year were seen on the move on 10 August, and 
again during the month and in September ; the last record 
was 21 September, when amongst them was a black- 
throated male. Birds in the brown stage of plumage were 
once seen : on 7 May, 1919 ; they were very wild. 
(Enanthe 1. leucura. 1 $ . 
Resident in very small numbers. It was observed passing 
on migration on 20 March. In autumn seen on passage on 
21 September, and a considerable number on 20 October. A 
nest found in a rock crevice on the Queen of Spain’s Chair 
on 9 May, 1919, had over 200 stones in its foundation. 
Another on 12 May next year, was in a hollow in a low cliff 
and had no stones at all. Both contained eggs. In the 
latter instance the hollow was so small that there was no 
room for a breast-work. 
Cisticola c. cisticola. 3d; 1 $ ; 1 juv. 
Breeds abundantly near Algeeiras in the wheatfields, and 
after the wheat is cut, in grassy patches. There are many 
late broods : a young bird not fully grown was seen on 
17 September. In August and September they were 
common along the river-banks, but departed in early October,
