California and Alaska are the first stop for Asian birds. All of these areas have benefited from the open-wallet policy of dedicated rarity chasers. The excitement does not have to be limited to our borders, however. When a rare Siberian accentor showed up at a feeder in Idaho, the rush was on. Sitting back and waiting for a rare bird to show up doesn't make sense.
Rare birds are, by definition, rare.
You can wait for decades for one, watching while money pours into other communities. If you want to take advantage you need to step up and make it happen. Instead of waiting for a bird, go and get it. Let's be up front about this. Catching and importing birds is illegal.
