tinguished by its grey coloration and pure white rump-patch. 
Montagu’s harrier is a somewhat smaller bird, and has black bars 
on the secondaries. In flight it is more graceful and buoyant 
than its relatives, and this is accomplished by three or four wing- 
beats, alternating with a long glide on half-raised pinions. It, 
again, nests annually in East Anglia, thanks to protection. 
There remains but one other bird of prey to mention here, 
and this is the sparrow-hawk. It may be easily recognized during 
flight by its short, rounded wings and long tail. The female, 
which is much larger than her mate, has the under parts distinctly 
barred. The breast of the male is similarly marked, but the bars, 
being of a pale rufous, or rust-colour, and much narrower, are less 
conspicuous. It has a very rapid and gliding flight, just above 
the ground, or along hedgerows, which it scours in its search for 
small birds. 
There may be many who will fare forth to find the harrier 
on the wing. If they succeed they will indeed be fortunate. But 
there is one bird that most certainly will be seen in the “harrier- 
country,” and that is the heron. There can be no mistaking him. 
He may be found, a large, grey bird, standing contemplative, 
knee-deep by the river’s margin, or in some ditch, awaiting the 
moment to strike at some unwary fish, frog, or water-vole. The 
moment he discovers that he is being watched he will be on the 
move. He rises heavily, almost awkwardly, with flapping wings
