I think it dates back to when crops were harvested manually and the wood pigeons would eat large amounts of grain etc. so they were treated as vermin - and still are.
I suspect the suggestion that culling makes no lasting difference is correct.
Wood pigeons still can do a lot of damage to vulnerable crops.
Vegetables like Peas and Brassicas - they love them. Haven't you heard gardeners complaining about the pigeons coming into their garden and destroying peas / cabbages / cauliflower / broccoli etc ? They can flock in their thousands in open fields and do real damage - destroying significant areas of crop. This is a common problem with winter oil seed rape in the UK - food is a bit harder to come by, so they concentrate on such an available source. Winter vegetables (brassicas) are simialrly vulnerable.
Exposed seed - if conditions hinder good coverage of seed, pigeons will pickmit up. Again, thousands can flock and once the seed is gone, it's gone. I had one field very badly affected the first year I was farming, great strips up the field with almost no crop following difficult sowing conditions.
I hate shooting, but it simply is not possible to scare pigeons away without some shooting. Bird scarers that go bang ! lose their scare factor if there are never any consequences. So some shooting is necesary. The objective then is to move the pigeons on - no, we recognize it is unrealistic to kill a significant proportion of the flock, killing is not really the farmers' objective. The people who do the shooting have to be motivated though. These are usually local sportsman who do it because they enjoy it. For them, bag size is important. If pigeons get the idea that a field is good, it can take a couple of days shooting to deter them. I suspect that is because what we see as one flock is actually a moving complex - lots of different birds joining and leaving.
So where are we trying to move them on to ? Other food sources, to the individual farmer, it doesn't matter so it could be (usually is) another farmer's crop.
I have tried to get a falconer to shift them with a peregrine. Basically there wasn't one within reasonable distance, so they couldn't afford the time necessary. The only one that came really wanted to fly at partridge :-(
I am not the only bird feeder that finds pigeons a nuisance either. A friend in Edinburgh gets up to 70 (including wood pigeon) if he puts feed down in his garden and complains how much they eat. I feed 3 or 4 tonnes each winter on my and another local farm. much of that is taken by unwelcome guests - pigeons, crows, pheasants, rabbits. The latter are at least attractive to the buzzards, but the buzzards are not efficient enough ! There are rodents too, but not too many - they are worth it for the stoats, kestrel, buzzard, owls etc. I don't shoot pigeons here. I discussed it with a local pigeon shooter and he said he wouldn't dream of trying for fear of hitting tweets. I'd hope the other pigeon shooters would also be concerned about non-target species.
