This shot was taken in the Canoe Point and Picnic Point State ParkClayton, NY 13624 I was able to approach the bird quite close being on a Zodiac boat. It was windy day and my lightweight boat was in constant movement, so iso800 (thank you Pentax for great low noise image capabilities camera) and 1/2500 saved this shot.

The Great Northern Loon (Gavia immer), is a large member of the loon, or diver, family of birds. The species is known as the Common Loon in North America and the Great Northern Diver in Eurasia.
Adults can range from 61 to 100 cm (24–40 inches) in length with a 122–152 cm (4–5-foot) wingspan, slightly smaller than the similar Yellow-billed Loon (or "White-billed Diver"). The weight can vary from 1.6 to 8 kg (3.6 to 17.6 lbs). On average a Great Northern Loon is about 81 cm (32 inches) long, has a wingspan of 136 cm (54 inches), and weighs about 4.1 kg (9 lbs).
The Great Northern Loon breeds in North America, Greenland, Iceland, and Great Britain. This species winters on sea coasts or on large lakes of south Europe and the United States.
