FOURTH SEASON (1921): RECORD 113 
opportunity to occupy such an eminently desirable 
territory. 
The definite results of last year had given me 
more than sufficient grounds for hope that this 
season would see the successful filming of the 
Cuckoo in the act of laying eggs, so I had entered 
into a contract with the Commercial and Educational 
Film Co. whereby the services of an expert operator 
were to be placed at my disposal at short notice. 
Let it suffice for the time being to say that most 
satisfactory film photographs were taken of the 
laying of the 2nd, 3rd, 4th, 12th, 13th, and 14th 
eggs and also of two glides preliminary to the 
laying of the 7th egg. 
By the end of April and thenceforwards the 
work of locating, identifying, and manipulating 
the nesting arrangements of the various pairs of 
Meadow Pipit fosterers naturally became most 
exacting, and forced us to be almost constantly on 
the common. On April 27 a male Cuckoo was 
first heard and on the 30th we saw the first evidence 
of the female. Two Cuckoos were flying together, 
1 one chasing or following calling “ cuck-00 ” and 
| spinning demonstratively round the other as though 
l welcoming her upon her return from the south, as 
& she settled silently at 9.45 a.m. in the ash tree (K 1 )
