Recently while doing a little internet surfing, one of our members came across the guidelines recommended by the Province of Manitoba for propane cannons used to ward off geese, ducks and cranes from grain fields. Manitoba suggests that propane cannons are louder than a shotgun and only one device is required per 40 acres when used in conjunction with other bird deterent devices such as flags, scare eye balloons, scare crows, etc.

The following description is taken directly from their web site:

Waterfowl Scaring Techniques:
Flags or scarecrows are usually the most effective and least expensive scaring method. The flags are typically fashioned from lath and a 3-mil black garbage bag. They should be placed at a rate of one per 10 acres or more, depending on the severity of the situation.

Propane scare cannons make a noise louder than a shotgun blast. One scare cannon per 40 acres provides optimum protection, especially when used with flags or scarecrows. Scare cannons should be timed to detonate every 10 to 20 minutes and they should be moved every 2-3 days.

It sure makes you wonder doesn't it. Some folks say that cannons are really of no value at all. Birds become accustomed to them in a matter of a few days and then just ignore the noise.

Others, like Manitoba, say that one cannon per forty acres is adequate.

Our industry people tell us that propane cannons are invaluable and the single most effective tool they have for deterring birds.

Our feeling is that none of these experts really know what they are talking about. All they are doing in the Fraser Valley is protecting the blueberry industry and basically allowing them to do whatever they please.

But this industry has become so irresponsible with propane cannon use that things are going to change. Cannons are going to become a thing of the past in the Fraser Valley!
