88 BRITISH BIRDS. [VOL. XI. 
p. 329). The same writer also includes the Blackbird among 
those species whose nests he has known to be used, and Mr. 
H. S. Gladstone gives another instance in the Birds of Dumfries- 
shire, p. 59 (cf. also Field, Aug. 18, 1900). The late Lieut. 
E. B. Dunlop also mentions breeding in nests of Blackbird 
and Thrush (MSS. notes). 
Mr. Grabham (loc. cit.) also gives a single instance of a Hedge- 
Sparrow’s nest being occupied, while Swallows’ nests have been 
recorded by Captain W. M. Congreve (B.B., X., p. 117), Mr. 
C.R. Haines (Birds of Rutland, p. 44), twice by Mr 8. Lewis 
(Zool., 1898, p. 429 and 1899, p. 556), the late A. G. Leigh, 
(B.B., IV., p. 120), and the Rev. C. Wolley Dod (Field, 
Aug. 14, 1897). This last case is that referred to by Howard 
Saunders. 
An attempt to breed in a House-Martin’s nest is mentioned 
in the Vert. Fauna of Cheshire (1., p. 184), while Mr. 8. P. 
Gordon met with a nest built on the top of that of the Dipper 
(Hill Birds of Scotland, p. 262). Including the Pied Wagtail 
and Robin, as recorded above by Mr. Owen, the nests of no 
fewer than thirteen species are now known to have been used 
by Spotted Flycatchers as breeding-sites, and probably the 
list might be still further extended. F. C. R. JouRDAIN. 
BREEDING-HABITS OF WILLOW-WARBLER AND 
NESTING-SITES AT CONSIDERABLE HEIGHTS - 
FROM GROUND. 
On the morning of June 20th, 1917, a Willow-Wren (Phyllo- 
scopus t. trochilus) was observed from one of the house- 
windows here (High Ackworth, Yorkshire), seeking, at the 
foot of an ivy-clad wall in the garden, a place in which to 
build its nest. A  building-site was very soon selected 
between the stems of the ivy and the wall, at a measured 
height of three feet six inches from the ground, and at a 
distance of about ten yards from the window. 
From the time of fixing upon the position for the nest, 
through the afternoon, until dusk, the bird was busily engaged 
in nest-building, the material for which, largely composed 
of peat-fibre, it found in the garden-beds close to the site. 
The nest was in an advanced state in the evening, having 
been roofed in. 
Building operations were continued on June 21st, and on 
the morning of June 22nd I thought I saw the bird’s mate, 
but, from previous and subsequent observations, I think I 
must have been mistaken. Feathers were carried to the nest 
on June 22nd. The feathers had to be fetched from a distance,
