THE BIRDS OF NEW JERSEY. 79 



It breeds in North America southward as far as the 

 Middle States. In New Jersey it is more frequent in win- 

 ter, rather common along the coast, where it preys on 

 water birds, but rather scarce in the interior. A few 

 breed along the upper Delaware. 



Government examination of 20 stomachs showed that 

 7 contained poultry or game birds, 9 other birds, 1 mice, 

 2 insects and 4 were empty.

This bird at all times and in intermediate plumages 

 can be easily identified by the pure white rump. 



The nest is built on the ground in a marsh, near water, 

 at the base of a bush or in the top of a tussock, composed 

 of dry grass and dead twigs with a spare lining of feathers. 

 In New Jersey mating begins in June. The eggs are 

 from four to six in number, rarely as many as eight, of a 

 dull white, sometimes with brown blotches, one and three- 

 quarters by one and two-fifths inches in size. 



The breeding location is the whole of North America to 

 Alaska. The birds are resident in New Jersey, but are 

 much more plentiful in winter. 



The food of this bird consists principally of meadow
