season ; they were laid probably about May 26, 
June 18 and 28 respectively. The fifth territory 
was occupied by another Sedge Warbler Cuckoo, 
and of her eggs only two were found. 
No great measure of success was met with 
amongst the Hedge-sparrow Cuckoos, the longest 
run being one of three eggs, and one of these was 
deposited in the nest of a Greenfinch.* But of 
course it is understood that the foregoing do not 
purport to be by any means the whole of the eggs 
laid by the Cuckoos concerned, only such as were 
found by Mr. Lees and his son. 
Amongst Mr. E. E. Pettitt’s results for 1921 
was a series of eleven eggs from one Cuckoo 
parasitic upon Reed Warblers. These eggs were 
also not taken as laid, but from what evidence is 
procurable they were in all probability deposited 
approximately as follows : June 1,3, 5, 7, 14, 16, 
18, 20, 22, 26, and 28. It is possible that the 
Cuckoo found no fosterer in suitable condition at 
the time of her long break. A final search of her 
territory in July revealed no further eggs or young, 
and Mr. Pettitt is convinced that he overlooked no 
eggs of this Cuckoo. In the previous season this
