quitting their retreats in the dusk of eveuing, or by moon- 

 light, at ^hich times they pursue their prey ; others may be 

 often seen abroad during dark and cloudy days, beating the 

 fields and hedges, in search of field mice, and small birds ; 

 and their flight is so extremely silentjthat unless they 

 cry, it is only accidentally they are discovered. They 

 mostly build in hollow trees, rocky caverns, lofty towers, 

 ruined buildings, and one species, the common Barn 

 Owl, generally takes up its abode in Barns, and out-build- 

 ings ; they feed on various kinds of small Quadrupeds, 

 Birds, and even Snakes and Lizards. They may sometimes 

 be caught in traps, baited with some living Animal. Nine 

 species are natives of Great Britain, for figures, see British 

 Ornithology, vol. 1, 2, 3.
