Fig. 12. Cow-bird Q). 



(a). About 7J- inches long. $ , iridescent black; head of 

 a warm silky brown. 9 , smaller, entirely brown ; beneath, 

 paler (and often streaky?). 



(&). The eggs average -OOX'GS of an inch, though greatly 

 varj'ing in size, and are white, thickly sprinkled, or finely 

 blotched, with brown and generally faint lilac. 



(c). The Cow-birds, like the Cuckoos of Europe,^^ present 

 a most interesting phenomenon in nature, for, instead of pro- 

 viding for their 3'oung, they deposit their eggs in the nests of 

 other birds. They are also, unlike all onr other birds, poi3'g- 

 amous, being equally without conjugal and parental affection. 

 I shall here follow their history from the earliest period of 

 their life, when they are left to the mercies 01' care of their 

 foster-parents, among whom I mn.y enumerate from my own 

 observations, the Blue Birds, Golden-crowned "Thruslies," 

 Maryland "Yellow-throats," Black and White "Creepers," 

 Summer Yellow Birds, several other warblers, Red-ej-ed and 

 White-eyed Vireos, " Chippers," several other sparrows, and 



85 Our cuckooB, who build their own nests, have been called "Cow-birds" from 

 their notes.
