Chapters 15 and 16, Skuas and Cuckoos 



The account of the skuas is taken principally from the chapter 

 relating to this group in Witherby and chapter 1 6 is based entirely upon 

 Stresemann's account of the cuckoo. The latter is probably the best 

 short summary up to date (see below). The other books mentioned in 

 the bibliography should be read and studied since they give a good 

 picture of the field work carried out in connection with the cuckoo. 

 Mr. H. N. Southern has kindly allowed us to read some notes from his 

 paper on the European cuckoo which should be published shortly.
