Horned Grebe, Hagg Lake, Washington County, Oregon, 1 November 2011 by Greg Gillson.
In autumn, Horned Grebes move from their breeding grounds to deeper ponds and lakes south or coastally to winter wherever deeper waters remain ice-free. Two birds were swimming and diving right under the floating dock at Hagg Lake on November 1, allowing me really great looks at 10-15 feet away.
Where can you find them right now?
