With a price tag of $229.99 the Bird Gard certainly isn’t the cheapest way to keep flying pests away from your garden. But if you’re using it to protect a small airport or a hanger it’s probably not a bad investment given what birds are capable of doing to an aircraft. The secret to the Bird Gard is that it uses the actual distress calls of birds to repel 8 different types of feathered foes including Starlings, Robins and Blue Jays. A single Bird Gard is able to protect an area up to 1 1/2 acres in size when set to full volume, but extension speakers ($39.99) with 100 feet of cable are also available to expand that range.
