60 ORNITHOLOGICAL RAMBLES.

 coming difficult to discover : accordingly, as the 

 season advances, we find the windhover leaving 

 our woods and forests for the open fields, espe- 

 cially where the sickle has revealed the long-con- 

 cealed runs of the field-mouse (Mus sylvaticus], 

 and where the scattered grain attracts wandering 

 parties of the short- tailed vole (Arvicola agrestis}. 

 This, the most destructive of our diminutive 

 quadrupeds, equally injurious to the farmer, the 

 gardener and the proprietor of young plantations, 

 is now devoured in considerable numbers by the 

 kestrel. With the view of satisfying myself on 

 this point, I have occasionally shot and dissected 

 the bird at this season, when the contents of the 

 stomach removed all possibility of doubt. I have 

 also found the harvest mouse (Mus messorius), 

 which, as well as the young of the long-tailed 

 species, is frequently bolted whole by this bird, 

 after the manner of an owl : but scarcely any kind

 occasion I observed a male kestrel beating a small 

 meadow for nearly an hour, flying much closer to

 paying still closer attention to his manoeuvres,
