Holmes,R. 1962 Erolia ferruginea 9 June Barrow, Alaska pond-marsh area 20' W. 1 1/4th Road in the same general locality - it flew across the road + off to the north - not to be seen again. The alert posture of the bird is similar that for alpina but the neck is longer + so the head is carried higher + the sickle- shaped bill is more pronounced (may be accentuated by the longer-stretched neck). The call note is an often-repeated chi-dip, chi-dip... - given in a high pitched - almost buzzy manner - has no quality of a Baird's Scr. display note. There was also a zip,zip... Note given on ground - colour is similar to (but high pitched - more like bairdi quality) The Dunlin's zhipp,zhipp. Also when the bird would land after flying - one wing was held vertically for about half a second - then lowered quickly with the normal folded position. 11 June 2 birds located about 600 yards No.1 Wahlshlag Slope adjacent to Elson Lagoon. - Watched for 1 1/2 hours - as they chased back + forth over an area 1 hill polygon + wet boughs - some sculpin mark & new - just becoming fine of snow. When first seen - they were flying low at high speed - over the ground - emitting a high pitched buzzy note.
