*PEREGRINE FALCON Falco peregrinus

Range F. p. calidus and F. p. ernesti Biak, Yapen.

Status Palearctic winter visitor (F. p. calidus) and rare visitor (F. p. ernesti). There are few records of resident ernesti and even fewer of the Palearctic migrant calidus anywhere in New Guinea (Beehler & Pratt 2016; KDB & SvB). 5 April 2006: Dutson (2006) saw one of the small resident subspecies in flight at dusk; June 2008: a member of a bird tour group saw one in southern Biak but without details ( van Beirs 2008 ) ; February 2011: two F. p. calidus ( Germi et al. 2013). 13 January 1994: P. Gregory (in litt. 2000) saw an adult with a rather pale grey mantle, perched in a dead tree on Owi , which was clearly not resident ernesti but presumably one of the Palearctic migrant subspecies .
