**AUSTRALIAN HOBBY Falco longipennis

Range Biak.

Status Austral migrant. Uncommon in New Guinea with very few records north of the central ranges (Beehler & Pratt 2016). On 13 June 1989, one perched on a radio mast near Biak airport shortly after dawn. A detailed telescope study revealed it to be an adult male: it had a large area of white on the head-sides with the collar extending to the back of the neck; pale throat becoming rufous on the underparts with indistinct dark markings on the breast; tail indistinctly barred and upperparts mid blue-grey ( JD & KDB) .
