woodwork, and joined together so as to be easily detached 
as a single structure. 
Each cup was perfectly finished and lined with hair and 
feathers, and the left-hand one contained two fresh and 
normal eggs. The entire nest was fresh and obviously the 
production of one pair of birds. The excellent photograph is 
by my friend Mr. Baynes. CLIFFORD BorRER. 
LATE STAY OF WILLOW-WARBLER IN YORKSHIRE. 
Mr. Sam Lonesorrom of Bingley informs me that he saw a 
Willow-Warbler (Phylloscopus trochilus) on October 31. 1917, 
by the side of the River Aire, near Bingley. He got within 
a yard or two of the bird and watched it for some time, so 
that no confusion with the Chiffchaff is possible. After the 
breeding-season they frequent my garden daily, but usually 
leave in September. E. P. BurrerFte.p. 
[A few stragglers are occasionally recorded during the latter 
part of October. Thus two were seen on the Skerries 
(Anglesey), October 21st-22nd, 1910, and one in Essex on 
October 22nd, 1911, while several came on board a P. & O. 
liner between Ushant and Finisterre on October 23, 1910; 
but as a rule they are rarely seen after the first half of 
October. A single bird was reported from Hampshire on 
November 5, 1912. (Cf. Bull. B. O. C., Vols. XXX., XXXII 
and XX XIV).—Ebs.] 
NUMBERS IN SWALLOW BROODS IN 1917. 
Havina sent you the percentage for broods of Swallows 
(Hirundo r. rustica) for several years, I now append the 
same for the past summer of 1917 for North Lancashire 
and Westmorland. 
1917 was a very good year for Swallows, but not so good 
as 1915, whereas 1916 was a bad year, and 1913 the worst 
on record. As I have already shown, June showed 65:5 per 
cent. of full broods as compared with 68 per cent. in June. 
1915. In my paragraph, antea p. 67, when comparing 
June’s heavy percentage of full broods with other years. 
I made the mistake of giving the whole summer’s percentage 
for 1915 and 1911. For the whole summer, 45:7 per cent. 
were full broods, as compared with 50 per cent. in 1915 
and 45 per cent. in 1911.
