I saw the this shorebird land on the forward deck of a cruise ship three days ago. Suppose it stopped to rest during migration. We were about 12 miles offshore heading from from Juneau to Seattle. I did notice it bobbing its tail once or twice, but did not hear any vocalizations. I believe that it was killdeer sized, but possibly a bit smaller.
I have narrowed the possibilities, but am not convinced.
Any and all suggestions appreciated,
MK
