There are usually only one or two sightings of this species in Worcester County each year, so I feel very fortunate. Here is a digi-scope shot, showing the thin bill pointed at a slight upward angle, lots of white on the cheeks and neck along with the slight build and structure (less than 1/2 the mass of a Common Loon).
There was also a Common Loon present far across the lake, on the Ashburnham side of the lake; and while visiting Crystal Lake, a few minutes later, I saw another Common Loon. The Wompanoag Common Loon was too far to check for leg bands and the Crystal lake bird had NO band on its left leg (the only one it lifted above the water).
