Black-Naped Oriole

A very common resident and familiar to many Singaporeans as it occurs whereever there are sufficient tall trees in which to perch and feed. It is a most attractive bird of brilliant yellow plumage with a wide black stripe through the eye and round the back of the neck, with a distinctive red bill.
It frequents tree tops and never comes to the ground preferring to feed on fruits, berries, and insects on the foliage. Its fast and direct flight can easily be recognised at a distance due to the unusual manner of freezing its flapping motion at intervals.

A very vocal bird particularly first thing in the morning and has a variety of flufy notes issued in a rapid ascending and descending manner. Call is a melodious four-note whistle, "what the devil!" with much individual variation.
