I have now observed 8 different Yellow-rumped Flycatchers (Ficedula zanthopygia) with yellow-rumps over the past 4 weeks – a “minor epidemic”. Some have become confiding and I can get close views and images.
This particular bird was feeding on the fruit of the Macaranga tanarius (Parasol Leaf Tree). The fruit is a “prickly three-celled yellow capsule” which contains a black seed in each cell. It is well noted in literature that birds feed on it and help with dispersion. I appreciate the support of Rosli Omar and Lim Koon Hup (Jim) for the tree identification (tree was posted earlier).
This bird (see Posts 1-4, images posted in different lighting and posture) has very pale yellow, most of it confined to the lower belly. There are some barring on the neck, a pale white eye ring but unsure about size of white stripe on the wing. I think this particular bird is a Ficedula zanthopygia but having difficulty deciding between an adult female or first-winter.
