CUCKOO 1 1 3 



young have been occasionally reported (see J. E. 

 Gray, Analyst, 1839, p. 67 ; Briggs, Zool, 1849, 

 p. 2603 ; Field, June 24, 1876 ; Feb. 17, 1877 ; July 

 31, 1897; and May 28, 1898, the last being a par- 

 ticularly interesting case). For an instance of a 

 Cuckoo laying in captivity, see Field, May 20, 1893. 

 As to its sucking the eggs of other birds, H. L. 

 Wilson, Field, Jan. 28, 1882; Zool., 1897, p. 515; 

 Gurney, Trans. Norf. Nat. Soc, vi. p. 373 ; and 

 turning out young birds from nest, " Our Summer 

 Migrants," 1875, and Hancock, Zool., 1886, p. 203. 

 For lists of birds in whose nests the egg of the 

 Cuckoo has been found, see " Our Summer Mi- 

 grants," 1875, p. 222; Bidwell, Trans. Norf. Nat. 

 Soc, iii. p. 526 ; Bladen, Trans. North Stafford. 

 Nat. Soc, 1896 ; in nest of Swallow, Zool., 1894, 

 p. 340. Blue eggs of Cuckoo, Zool., 1880, pp. 361, 

 400. As to variation of plumage, a white Cuckoo 

 obtained in Norfolk is described, Zool., 1896, p. 

 174; and the hepatic plumage of the Cuckoo is 

 discussed, Zool., 1895, pp. 257-263. An excellent 

 article on the " Economy of the Cuckoo," by J. H. 

 Gurney, is printed in the Trans. Norfolk Nat. Soc, 

 vol. vi. pp. 365-384, with illustrations. 



It has been stated that only the male bird cries 

 "cuckoo" (Newton, "Diet. Birds," p. 119); but 

 Sterland asserts that two were shot in the act of 

 calling "cuckoo," which proved to be hen birds 

 ("Birds of Sherwood Forest," p. 157). 



Cuckoos have been successfully kept in confine- 

 ment during the winter. See Field, Feb. 7, 1863;
