more daiitroroiis to birds than the Grev Fox, but 1 tliink 

 it is mainly tlie farmer's hog that prevents the rearing 

 of all kinds of birds nesting on the ground in the timber. 

 Towliees, Ovenbirds and several other speeies nesting on 

 the ground are extenninated in woodlands where hogs are 

 kei)t, and most of our Missouri woods are overrun by 

 hogs. They are as destructive to eggs as to young birds, 

 and wliere no young are reared the species must soon 

 disappear. 



Besides the birds already mentioned there are several 

 kinds of Hawks and Owls to be found here in winter. The 

 Screech, Barred and Great Horned Owls are true perma- 

 nent residents, while the Short-eared, Long-eared and 

 Saw-whet Owls may be counted among the winter visit- 

 ants. The Sparrowhawk is a real permanent resident in 

 St. Louis, but has only become so since the English Spar- 

 row has multi])lied so wonderfully, affording the Hawk a 

 never-failing provision at all times. Of the large ^fouse- 

 hawks, the Red-tailed is with us all the year, the Red- 

 shouldered being a less hardy bird, while the ^farsh 

 Hawk and Rough-legged Hawk are regular winter 

 visitants.
