'unique ideas' dreams, my friend, do come true :)
A grocery store nearby had issue of many pigeons entering their premises and roaming around inside [without generating any revenue/sales :) ] .. pigeons had got smart to tailgate genuine shoppers and learned to use the automatic open/close doors .. it seems, the owners/managers have found a very cost effective (simple and no-tech!) solution to their problem .. they placed a make/believe eagle "figurine" just at the entrance which might scare the intruding friendly birds with its piercing eyes .. I want to find out about the effectiveness/results ..
