 from three to five in number, white, with brown spots, 

 the latter forming a wreath near the large end, and two- 

 thirds by one-half an inch in size. 



The birds breed in northern New England as far north 

 as Hudson's Bay and spend the winter in the Bahamas, 

 Cuba and Central America. In New Jersey they are 

 common in migrations, occurring from May 10 to May 20
