Bee-E.\ters in Scotland. — With reference to Mr. J. 

 Kirke Nash's interesting article on this subject in our last 

 number (pp. 56-58), we are informed that the bird mentioned 

 by Mr. Nash as having been caught by a gardener has been 

 presented to the Royal Scottish Museum. — Eds. 



Cuckoo's Egg in Tree-Sparrow's Nest. — At the meeting 

 of the British Ornithologists' Club on June gth, 1920 {Bull. 

 B.O.C., XL., p. 155) Mr. P. F. Bunyard exhibited a Cuculus 

 canorus egg, together with four of Passer montamis that 

 had been taken at Banham, Norfolk, on May 30th, 1918, 

 by Mr. L. W. Leader from a nest in a pollard willow. So far 

 as the exhibitor was aware, this was the only instance known 

 of the Tree-Sparrow being victimized in the British Islands ; 

 the Cuckoo's egg was of the common greyish type and weighed 

 0.222 g. There is a similar combination in the National 

 Collection, taken in Germany and part of the Crowley Bequest, 

 and this was probably one of the two that were included in 

 the exhibition of Cuckoo's eggs at the above-mentioned club 

 on March 31st, 1896 [op. cit., V., p. xxxiv.). Besides these 

 cases Mr. J. Ramberg had a clutch of Tree-Sparrow with a 

 Cuckoo's egg from Styria, and Dresser {Birds of Europe, V., 

 p. 210) quotes Mr. A. Benzon of Copenhagen as his authority 

 for including the Tree-Sparrow as a foster-parent. A note 

 by T. N. Postlethwaite {Naturalist, 1885, p. 127) on a young 

 Cuckoo taken from a hole in a willow may refer to either the 

 Tree or House-Sparrow, and is inconclusive.
