X Preface. 



No. 3, shows the young bird still on the cuckoo's back — the 

 cuckoo well up in the nest ; taken five or six seconds after No. 2. 



No. 4, shows the cuckoo right at top of the nest— the other 

 young bird at first slipping off its back. You will in this one 

 notice that the cuckoo has its wings extended, to keep the bird 

 on its back from rolling back into the nest. 



[Nos. 3 and 4 were reproduced in The Feathered World, and 

 are now, by the kind consent of all the parties concerned — Mrs. 

 Comyns-Lewer, Mr. Craig, and Mr. J. Peat-Millar— here printed 

 at p. 28,] 



No. 5, shows the young cuckoo settling down in the nest, after 

 having finished his murderous work. 



[I am sorry to say, adds Mr. Miller, that the young bird in 

 No. 5 is rather indistinct, owing to the fact that, when it was 

 thrown out of the nest, it was out of the actual focus of the 

 lens.] 



No. 6, taken at a different time, shows the young cuckoo with 

 the egg in the hollow of the back. 



No. 7 is a snapshot of the cuckoo, after having reached the 

 age of ten or eleven days, living in perfect harmony with an- 

 other young bird, which Mr. Craig had put there with the view 

 of trying the experiment. They had apparently found the nest 

 too small for them, and they were lying snugly ensconced close 

 together in the soft grass at the side of the nest. In that posi- 

 tion this photograph was taken. 



[This goes further to prove that the young cuckoo, in about 

 eight or nine days, at furthest, loses completely the impulse to 

 throw out what is beside it.] 



[No. 6 is given as the frontispiece to this volume, and No. 7 

 at p. 45, with many thanks to Mr. Craig and Mr. Peat-Millar, 

 for freely and cordially giving me permission to use them.]
