Holmes,R. 1962 Ereunetes gusillas 8june Barrow, Alaska One heard aerial displaying - near Elson Lagoon - Wobbleblog Slough - At least See next V.Oth. 10 June Seen frequently in Brittan's barrel ridge area - as well as several other Elson Bluffs - north Wobbleblog. 13 June at least 2 displaying birds in the core of Brittan's area. With much chasing going on. The birds give a trill seeeeeeee - for short periods on the ground - They may end then - it may turn into the motor call. The speed wheel, however, is not given for more than 3 sec on the ground. In the air they quarter down curved ways - sometimes starting with the trill - followed by the motor call - then given the trill upon landing. And I have congruent on the left out. Often the aerial display is interrupted by a chase or another bird displaying nearby. The 1st bird will settle every at a 45° V - angle in swiftly & evocatively - giving the trill.- Once when 3 birds landed - 2 went into what I have been calling "courtship" posture - head fanned, tail cocked, wings held down + among a dull & varied trill calls. The group lock step - one crocheted - another toward.
