of llic young l)inls were sufririciUly advanced to srrnmblc out 

 of the nest, and the otlier three were of different ages, one being 

 just hatched, another several days old, and the third still further 

 advanced, covered with " pen "-feathers, so that it would have 

 been able to fly in about a week. His friend Mr. Rhett, in 

 whose garden this nest was found, assured him that he had 

 known as many as eleven young Cuckoos to be reared in a 

 nest in the course of one season. The late Dr. Brewer says 

 that the breeding-season lasts from one to four months, so that 

 it will be .seen that the nesting-habits of the American Cuckoo 

 differ strikingly from those of their European cousins.
