"THE CUCKOO'S SECRET" 



BY 



EDGAR CHANCE, M.B.O.U. 



Illustrated. Sm. Demy 8vo. 7s. 6d. net. 



"Will at once excite and satisfy those who study bird-life." — Birming- 

 ham Gazette. 



" The written word tells much that is invisible on the film. . The 



whole is a singular, a unique triumph in persistent and scientific observation." — 

 Daily Mail. 



" In almost every detail this plain narrative of facts, faithfully recorded in 

 notes and confirmed by photographs and films, completely upsets all the pre- 

 conceived ideas of naturalists as to the way in which the cuckoo victimises her 

 dupes ; and it is probably the best ..ddition which has been made for years to 

 British natural history." — Daily Sketch.
