That would be coo coo.
My barber also has a dove releasing service, for weddings and such. He says the birds have to be kept in captivity into the second year of being paired before they will reliably return home.
He says releasers occasionally lose birds due to unexpected weather changes and predators.
What happens to the doves if it is a “shotgun” wedding? Or do you release clay pigeons at such events?
Isn’t the symbolism of freeing the birds ruined by the idea that they are homing doves and go willingly back to captivity?
To Irishman:
My parents’ memorial service was far too emotional a time for us to bother thinking about the captivity and homing instincts of the damned birds. For us, the circling of the birds, and then their flight away from us was symbolic of the departure of my parents’ souls from this Earth.
And the horrible punning remarks upthread would have delighted my parents’ sense of humor!

[edited to add: my sister was also thinking continually while she held her dove, “Please don’t poop on me. Please don’t poop on me.” This also would have tickled my parents!]
Hey, even doves have pride.
Interestingly enough, Dodo’s were considered inedible, tasted lousy, from what I’ve read.
Never read a word about eating dove.
But, I HAVE prepared squab and ate it. 
I had a friend who told me that her boss, when a poor student, used to snare pigeons on the window-ledge to get something to eat.
In Soviet Russia, doves release YOU!
No, they release on you.
