[Tweeters] American Dipper over Saltwater?

[Steve Loitz via Tweeters]

Hans,

I have seen AMDIs near salt water in winter, e.g., Larabee State Park,
although I've never seen one swimming or feeding in salt water.

Many, very likely most, of WA's AMDIs migrate vertically as the streams,
high lakes and tarns in which they feed during breeding season and
throughout the summer freeze and/or become snow-covered. Each year, we
mountain travelers observe hundreds of AMDIs descending from their breeding
grounds in winter to the Yakima River, Methow River, Tieton River and
tributaries thereof. Dippers are common IDs on the Yakima River in winter.
I have counted 20+ AMDIs on the Tieton River on several drives home from
mid-winter skiing at White Pass. I suspect that many, possibly most, of
those birds breed on the Tumac Plateau (north of White Pass).
