Common Snipe

According to Fisher and Acorn's book, "Birds of Alberta", "the common Snipe is both secretive and well camouflaged, so few people notice it until it flushes suddenly from a nearby grassy tussock. As soon as the Snipe takes to the air, it performs a series of quick zigzags - an evasive maneuver designed to confuse predators. Because of this habit, Snipes were among the most difficult birds to shoot (in the days when shorebirds were hunted for sport), and skilled sportsmen were known as "snipers" - a term later adopted by the military."
