Mr. BuNYARD also exhibited a clutch o£ Hedge- Sparrows 

 from Surrey, with a Blue Cuckoo's egg similar in colour to 

 those o£ the fosterers, all o£ which were highly incubated. 



Mr. Bunyard had carefully examined the embryos, and 

 found that the Cuckoo's egg' was quite different to those 



* The Tit's nest was placed in a shallow box, which the birds had 

 completely filled with moss etc. The actual nest was placed just inside 

 the corner, the only part of the box left uncovered by other boxes piled 

 on top of a shed, 



t Seven clutches containing one Cuckoo each, from the same bird, 

 extending over three seasons, 1916-1918. 



J Remains of Cuckoo's egg, which had been destroyed, together with 

 those of the fosterer, probably by a mouse. 



§ T-^elve clutches with one Cuckoo each from the same bird, extending 

 over four seasons, 1907-1910. This Cuckoo was obviously parasitic on 

 the Hedge-Sparrow, but when nests of her natural fosterer were not 

 available she used Blackcap- Warbler three times, Garden- Warbler and 

 Linnet once each. 



These are very large distinctive eggs, with blue-green ground richly 

 marked with rich brown.
