As a contrast, and in illustration of the degree of variability 
possible in the size and weight of Cuckoos’ eggs, apart from 
questions of colour and markings, it is striking to note that the 
average weight of the Reed Warbler Cuckoo series of 19 eggs 
taken by Mr. G. J. Scholey in 1921 was 247*6 milligrammes.
