Holmes, R. 1962 13. Erolia ferruginea 12 June Barrow, Alaska gave the "slow flight" & the song was uttered. - so this could be involved in some degree territorial or aggressive action. (The when for tom. [illegible] + song 91m to 850ft. wide.) At times, the bird would interrupt his feeding to give 1-6 of the whines. (In one instance 24 were given - 1 every 2 sec. - in succession). (These are produced by the bird taking in a large amount of air - i: puffing itself up - then making the sound in the exhale - deflating. The pulsation effect is quite noticeable - series of white pump is put into view with whom & the sinks below the body, sequence on exhale). Or giving the whines - the bird is in an alert posture - usually with head up - but not accentuated as in some of the Dunlin displays. Once as the bird moved in close to us - acting rather disturbed & nervous - (just after leaving a nest up) - it gave a loud cok, cok, cok - when in very simple & clear alarm note a disturbance noted (Dunlin). As the bird came close to us, it remained in the hunched posture, acting nervously. The 2 mees gave a loud - beeble-keep or cheer-keep. & then resumed feeding. This
