Does anyone use Falconry for bird work?

Just something I've bounced around in my head and thought I'd ask? Thanks.

Many people do, takes dedication and of course all the training, permits, and so on down the line, but absolutely people use them for a variety of bird control activities.

Some of the organic blueberry growers here in Oregon employ a guy from California for about 6-8 weeks every summer to fly falcons over the fields. Keeps the starlings and blackbirds away like no other method.
