Oh, c'mon Capot.
"It's a little known FACT (my emphasis) that..."
Care to cite a credible reference for that, mate?
'Homing Pigeons' can indeed navigate their way home from starting points many hundreds of miles distant - places they've never been to before.
More recently, it's also been found that they can be trained to spot small vessels (and wreckage) in poor visibility from surveillance and search aircraft.
They are suitably rewarded each time they get it right.
A neighbour used to race pigeons and, for some of the longer races, accepted a loss-rate of around 2%.
Those lost ones and their progeny are the ones that infest every nook and cranny of our city parks and buildings.
I'm aware of some public-spirited(?) citizens that get up very early in the morning to distribute a daily ration of Warfarin pellets.
