Great Shearwater Scott Spangenberg

Great Shearwater photo by Scott Spangenberg. This bird is taking off from the water on a day with little wind forcing it to run on the water. This is also a good photograph of Great Shearwater to notice the black capped appearance and the underwing pattern.

Four Shearwater Day
You can see 4 species of shearwaters on a good trip to Stellwagen Bank: Great, Sooty, Manx, and Corys. If you see Audubon's you can call it a great Shearwater day.  A Little Shearwater on a shelf edge trip makes your day exceptional.

Shearwater Flight
The flight of the shearwaters (and Northern Fulmar ) especially with some decent sized waves is both beautiful and remarkable.

Alternating flapping and gliding on stiff wings, the Shearwater banks over the waves just above the surface. Just when you think the bird will plunge into a wave it rises in a high arch only to glide down into the next trough.

In John Slovin’s photo of the Cory's Shearwater the left wing seems to almost touch the water. Beautiful photo John.  Thanks for sharing.


When taking off from the water, the shearwater faces into the wind and runs on the water. This Sooty Shearwater is taking off with little wind (notice the smooth sea) forcing it to run further.

Even flying in an almost straight line the shearwater alternates flapping with gliding. Watch closely and you may notice a shearwater catch up and pass a boat going 25 knots.
