NATURAL HISTORY OF SOUTH AFRICA 



little sawdust or dry earth is all that is necessary. The 

 boxes should be screwed very firmly to the tree trunk 

 from 6 to 10 feet above ground for small birds. 

 See that they are out of reach of cats and tree snakes. 

 Branches of the thorny mimosa nailed below or round 

 the box will help to keep cats off. 



Crocheted Ball filled with cotton 

 batting and feathers, with short 

 lengths of yarn, string, and 

 horse - hair added, for nest 

 building. 



Nesting Boxes like this one may 

 be placed on poles, trees, or 

 under the eaves of houses. 



The upper part of the box should incline slightly 

 forward. Boxes ought not to be too near together, 

 and the birds should not be disturbed while nesting. 

 The boxes should vary in shape. Some birds prefer 

 deep boxes, and others medium or shallow. 



The tree-hole boxes are bored in the solid wood. 

 The lids of closed nesting boxes should be hinged 

 or screwed so that they may be easily opened for 

 a yearly cleaning.
