CALENDAR FOB ATTRACTING AND PROTECTING BIRDS. 



October is the month for reflection in matters appertaining to the 

 protection of birds. We must now make up our minds what to do. 

 Tlie most important thing is the creation of opportunities for nesting, 

 namely, the hanging up of nesting-boxes, and the planting of shelter- 

 woods. 



We can treat these matters briefly here, as we need only refer to the 

 corresponding chapters in this book : nesting-boxes, pp. 30-5.3 ; 

 shelter-woods, pp. 54-71. 



It will be sufficient to draw attention to the fact that the ground 

 that is destined for a shelter-wood must be deeply dug in autumn 

 and left in great clods, so that the frost penetrates well. The planting 

 is done in the following spring. The rec^uisite plants can be ordered 

 now and kept well ^^'rapped up till the time of planting. 



It is advisable to order nesting-boxes now, as the following month 

 is the best time for hanging them up. Berlepsch's nesting-boxes are 

 the only ones that can be recommended, and these should bear the 

 registered trade-mark. (For prices see advertisement pages.) 



These are the only boxes that possess the important improvement 

 described on p. 38. The " Kommission zur Foerderung des Vogel 

 schutzes " therefore begs that all interested in the matter will only 

 use those nesting-boxes that bear this trade-mark. This is the only 

 way of repairing to a certain extent the error fl-hieh Baron von 

 Berlepsch committed when he did not legally protect his boxes, and of 

 protecting the pubhc from failures due to worthless imitations.
