For a market reseach I am currently conducting in the field of "Bird Control" (distancing birds away, especially pigeons), I need information about the YEARLY USA market size: comprised by the combined yearly purchases of private home owners/industrial/federal/state purchases, for the last year, or even better: recent few years. I need info on all types of equipment to drive pest birds away, but especially about the "Anti-Bird Spike/needle Units". I will also appreciate such info about Canada, Western/Central European countries (England, France, Benelux countries, Germany, Spain, Italy, greece, Scandinavian countries, Austria, Hungary, Bulgaria, Poland, etc...) and also about South-Africa and Australia. Such info about any other country would be welcome as well...
I think that good answers could come from people either working in this field (bird control) in their countries (in companies or in universities or in health or quality-of-life departments, who deal with the relationships of birds/humans or deal with the yearly amount of bird damages of all types in the above mentioned countries, etc... ).
Thnx.
