occasionally for funerals we have "dove releases"...but they are really white homing pigeons. There are local companies in all the cities I have worked (Toronto, Barrie, Kitchener). To be honest, they often don't work out as well as expected. Last one I did they flew like 10 feet, landed and sat there staring at us. And a colleague told me he did one and one of the birds got picked off by a hawk as everyone watched "the spirit ascending". Not sure if it really happened, but pretty neat story.
