DESCRIPTION OF THE BIRD(s)
Scolopacidae Shorebird with straight bill, probing in the mud (distinctive dowitcher behavior).
In flight, white stripe down mantle (between scapulars) distinctive.
BEHAVIOR OF THE BIRD(s)
Feeding along shoreline, probing behavior distinctive to dowitcher.
4 Feb. birds seen in flock flying restlessly through the area.
HOW AND WHEN DID YOU POSITIVELY IDENTIFY THE BIRD, AND WHAT CLINCHED THE IDENTIFICATION FOR YOU?
Positively identified while observing. Shape and behavior distinctive.

4 Feb. I heard the distinctive LBDO call of the birds in flight, and saw the distinctive white stripe on the mantle.
HOW DID YOU ELIMINATE SIMILAR SPECIES? WHAT WERE THEY?
Birds identified to L. scolopaceus (as opposed to griseus) primarily due to being the more expected and numerous of the two to occur in Idaho, as well as the relative similarities of the two birds. Additionally, the birds were present again the following day on 4 February with 15 additional individuals seen well in flight and heard calling, further supporting the identification to L. scolopaceus.
WHAT IS YOUR EXPERIENCE WITH THIS (AND SIMILAR) SPECIES?
Experience with both Limnodrammus spp. across their range, including the breeding grounds.
DESCRIBE YOUR GENERAL BIRDING EXPERIENCE
I've been birding since I was a kid, with serious study for the past 7 years or so. Although I'm not the best birder and certainly make mistakes, I think I'd be rated an above average birder.
