What you say here is soo 100% true.Every birds is it's own unique individual.
Perhaps it is common knowledge on this channel, but young bird season (when the current season's birds are raced) is late summer and fall, in the northern hemisphere.
Dave was exactly as you said, a wayward racer in his first year, still learning the ropes.
It is an unfortunate side effect of pigeons reproducing fairly easily, and a racing homer's entire purpose being to *come home*, preferably as rapidly as possible.... that those birds which fail to do so are often not greatly valued by the owner.
When I raced, I always wanted my birds back. However it isn't uncommon for people to have absolutely no interest their birds as soon as they decide to wander off.
It might appear heartless, as Dave clearly has personality. But consider a barnyard cross chicken or goose, or a hybridized pheasant. Those aren't typically what a good breeder is looking for, and putting them into the freezer is considered just fine in most cases.
I'm sorry that you didn't get a response from the Scottish racing union. They probably did notify the owner. However eating pigeons in the US it's a pretty niche thing these days, often looked down upon. I assume it isn't terribly different where your are. And the owner apparently didn't feel it worth the time to call you and tell you he didn't want the bird back.
I'm not saying this is a great place to be. And I was always anxious to get mine back. They were more pets than performance animals. Which probably explains why I didn't win races. But the older fellow who is going to be culling under performers anyway, faced with possibly talking to an animal rights activist, yeah. I'm sorry you didn't get more of a response, but I'm not terribly surprised.
Pigeons are one of my favorite birds, and I'm thrilled that you got to spend some time with Dave.
*edits because I can't spell
I only kept pigeons as pets, and did tosses. Loft flying them daily. I have been around pigeon racer peeps. They took their looser's to the Butcher shop.
There was sizeable ca$h involved within the clubs on races.
