INTERESTING FACTS
The Wedge-tailed Shearwater was first described in 1789 by Johan Friedrich Gmelin, a German naturalist. An alternate common name is the Pacific Shearwater, and it is one of the species that is sometimes referred to as a Muttonbird. They are monogamous, forming long term pair bonds that last for several years. Divorce between pairs occurs after breeding seasons that end in failure. A group of shearwaters are collectively known as an "improbability" of shearwaters.
