A covey of young grouse whirr heavily over the nearest brae—but the marsh harrier remains.
The young ones take to the water as soon as they are hatched, but they often fall a prey to the marsh harrier.
The marsh harrier is a widely dispersed species, being found, says Temminck, in all countries where there are marshes.
The marsh harrier which measures twenty-one to twenty-three inches is a formidable foe to moles and mice, rabbits and reptiles.
In habits both birds resemble the marsh harrier, but do not confine themselves to damp places.
