moors. The flight of the Hen Harrier is always low, 
but at the same time smooth and buoyant. It 
feeds on small birds and the young of larger ones, 
occasionally on grouse and partridges, and often on 
young rabbits, hares, mice, frogs, &c. It breeds 
on the open wastes, and frequently in thick furze 
covers, placing its nest on the ground. The eggs, 
four or five in number, are of a pale bluish white, 
and round at each end. In the first year the 
young males are similar in appearance to the 
females, after which they gradually assume the 
grey plumage that distinguishes the adult.

The Harrier Marsh Hawk preys on waterfowl,

lizards, fish, and insects. Its flight is slow and

tion the males often soar to a considerable height, 
and remain suspended in the air for a long period,
