FOURTH SEASON (1921): RECORD 129 
when the Cuckoo laid her first egg, and as I walked 
up to the tree the Cuckoo suddenly bustled out. 
From then onwards she showed unusual deter- 
mination to return quickly to the tree. So we drew 
around her, now knowing that she intended to 
victimise No. 6 pair. But unfortunately we could 
not find the nest, although the Pipits did their best 
to show it both to us and the Cuckoo ! At 5.5 p.m. 
she floated across the common, passed on to the 
centre orchard and then paid a momentary visit 
to the site of No. y 3 ; Miss Turner, still in her 
hide, actually saw the shadow of the Cuckoo across 
her lens. 
However, the Cuckoo returned to her former 
tree, and at 5.10 she dropped down to the nest for 
a moment. She flew back to a bare bough in the 
same tree, from which she quickly floated down to 
the nest which we had been unable to find. She 
took twenty-eight seconds for the glide plus the 
stay at the nest, before flying on to the centre 
orchard. The glide distance was 35 yards and it 
alone took seven seconds. On going to the nest 
we found three of the fosterer’s eggs and the sixth 
of the Cuckoo ; one of the Pipits continued to 
carry the grub about in its beak after I had removed 
all the eggs and restarted the pair.
