ORIENTAL DOLLARBIRD Eurystomus orientalis #

Range E. o. pacificus Biak, Supiori ; E. o. waigiouensis Yapen.

Status Austral migrant. Beehler & Pratt (2016) noted that resident E. o. waigiouensis is scarce on New Guinea’s north coast but in Teluk Cenderawasih has been recorded on Yapen. Austral migrant E. o. pacificus is widespread and common on Biak in April ‒ November. 5 June 1990: a loose aggregation of c.50 hawked at dawn over the hotel near Biak airport ( KDB). Presumably these were recent arrivals. 12 August 1994: 15 near Waspdori Falls (D. Roberson, eBird checklist S6813709).
