Holmes,R 1963 L. mauri 22 jim Banow, Alaska Located at least 2 birds on beach ridge. One did an aerial display - hovering in outstretched, quivering wings - at 15' above ground. The bird rose fell ±1 foot while it gave to song. The song has a buzzy flat tone, almost shrill quality & very roughly can be characterized in the following way. eh-eh-eh-eeh-cheer-Yer za - za - za - The cheer component is the most distinct shrill section & drawn out in time. After landing the bird fed along the ridge fip & while doing so, was chased 3X by a semi-pel - who would land nearby, raise its wing & shifty run it tail above its hyperrubul & then dash at the WS - who would run a few steps - would fly short feet & land. The next - 3X - the birds flew off with SB chasing the WS & giving its shrilled call note. After flying 10', the SB turned over, gave a brief aerial display from a perched spot. The WS then returned behind (Phalae) Red B (located in Reserve)
