THIRD SEASON (1920) : PRELIMINARY 49 
Note. — F rom the rapidity with which the next nest was 
built, it seems certain that the act of removing all the eggs 
from a nest before the clutch has been completed, causes 
the Pipit to “ forsake ” even though she may continue to 
use the deserted nest for the purpose of laying the remaining 
eggs of her clutch. 
Fourth Nest (3). 
Saturday , June 26, 10.30 a.m. to 12 noon. — Observed the 
Cuckoo watching this pair building their fourth nest and 
when she had flown away without visiting the nesting site 
(the Cuckoo never victimised this nest) we found the nest 
apparently approaching completion. 
Wednesday , June 30. — First egg laid. 
Friday , July 2. — Only two eggs laid. 
Sunday , July 4. — Three eggs laid and bird sitting. 
Added two more fresh eggs from C Hill.
