 pi^;eons have become accust.op.ed to feeding, on baits placed about and under the •

Shooting 



The use of firear.is is usually prohibited in citie.:>j e^voept under special 

 peraission of the pol.ice deya.rt.uent , For this reason sI.ootint_, caiinot be recom- 

 mende:- a? a ^:ener<-J. procedure in controllint-, objectionable city-duelling; pij'^.eons. . 

 Per-.ic5lon to shoot the. pl^eo.ii^, ao^vever, can usually bo obtained frou the' police 

 i.f ohe birds are fev,' in n^r.^ber and are particularly objiectionable. A 22-caliber

Poisoning 



Althou;;,h. the use of poisoned baits is effective and is reasonably safe vjheh 

 the operati''~n.s are. coivductsd b,;- experienced persons, this .aethod of pigeon control 

 is not reco..Ji'a.3nded f:;r the, jseneral public. Most poisons are to:iic to -ij^ljiials in 

 t^eneral, and there is de^-n-er thv-.t oats or dogs i.iay eat the freshly kil.lad birds 

 and obtain lethal doses froa the grain. in the birds' crops. Further. aoro;^ the ex- 

 posure of poison witliin the lii;iits of tov.ns and cities is, as a riue, prohibited 

 by law « 



Where nunicipalities eu-.ploy .■;en experienced in ^.-est control, poisoning opera-
