Holmes, R. 1961 Croethia alba 7 June Barrow, Alaska stating. The birds collected have been fat & an apparently still migrating. 15 June 1 bird collected, just Mr. T. I. T. A. B. After minutes later, a part (?) was seen further nearby. Two were left - on the clams. They might be breeding. 17 June Two pair of Sanderlings seen in area described above. The note given - Flight - a chug, chug....... - different from any other peep & not heard from wandering birds. The alarm note is, a house, Thrush croak - much lower in pitch & more grating than the RB. The bill was not heard. Once when the 2 birds landed, we assumed the mouse- run posture, ran over to a depression & settled in - it appeared to shuffle-tooth forth - forcing the breast into the ground - lean the tail projecting up at a 50° L. After several seconds, it flew off in chord The other bird. The depression cover not be found oftener - so maybe this is part I courtship - active. Seen in Bard-Hemi pair - where the displaying male went through the saw procedure.
