If you have had enough of the sparrows then chances are others are feeling the same way , inlist some helpers the birds are probably nesting and sheltering somewhere near by , pinetrees and date palms are a favorite for them and also starlings , so think about hitting them while they are asleep . Follow them just before dark and see where they hide , raid there nests , terrorise them if nothing else it will make you feel better .
If you always do what youve always done thats all you will ever do !!!
