Observations on the Cuckoo. By Edgar Chance. — This is an extremely 

 interesting account of an intensive study of the Cuckoos of a common in 

 Worcestershire. Assuming that the eggs of each Cuckoo are always 

 remarkably similar and are laid in the nests of the same species of bird 

 in which the Cuckoo was reared, which seems to be pretty well proven, 

 the author found that the Cuckoo under observation laid eighteen eggs in 

 as many nests of the Meadow Pipit, on this common in the season of 1919. 

 It seems that the Cuckoo removes one of the Pipit's eggs in case a full 

 clutch is deposited before its visit to the nest. Mr. Chance is of opinion 

 that the bird carries its egg to the nest of the foster parent in its bill but 

 he has not yet been able to see the egg deposited although he spent a 

 night on the common in the hope of solving this problem. The evidence 

 presented seems to show that the Cuckoo locates every nest of the species 

 upon which it is parasitic, that has been built in the district which it covers, 

 and lays an egg about every two days until each nest is supplied; the 

 number of eggs being thus dependent upon the number of nests. 



British ornithologists have a most interesting problem before them 

 in ascertaining the exact life history of this peculiar bird. Why do not 

 some of our American bird students set about solving the same problem 

 in the case of the Cow Bird? If the great army of egg collectors desire to 

 demonstrate that there is really some science in their hobby here is their 

 opportunity.
