Mugimaki Flycatcher

Location :Kledang-Sayong Forest Reserve, Ipoh, Perak, Malaysia
Date : 3 December 2018
English synonyms:Black-and-orange Flycatcher, Robin Flycatcher
Bird Family :Muscicapini - Old World Flycatchers & Niltavas
Red Data Status :Least Concern
Remarks :I saw 5 Mugimaki Flycatchers at the same location today. Two were first winter females and the other three first winter males. The females were generally paler than the first winter males and this was very obvious in the field. They lacked white at the outer base of the tail and had no clear pale supercilium. They also had “pointed rather than, in adults, blunt tail-feather tips”. (see Wells 2007 on first winter birds). Much of the feeding by all 5 birds was aerial sallies for flying insects; they will usually land at a different site from where they took off. I also saw them plucking insects from the under surface of leaves. In the past I have seen them land and pick insects off seeding bamboo. Regarding frugivory, in the past I have seen them feed on fruit Macaranga bancana and other unrecognised fruit. On this occasion I saw them feeding on the black seeds and orange stalks (arils) of the Acacia mangium trees. One image shows a bird with an Acacia mangium seed in the beak. On two occasions I saw them struggling with the seeds and they had to regurgitated them out before swallowing them back (lots of throat movements). The technique used to feed on the Acacia mangium is a sallying out to an open pod and a fly-by-lunge to grab the fruit; then a ‘drop’ to a branch to feed.
Taxonomic Notes :Monotypic.
