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 .
