Physical description Click here for a physical description The two sexes of White-spectacled Bulbuls look alike. They have a dark-grey head and neck, except for light-grey eye-rings. The back of the head is shaped into a small crest. The rest of the front, from the chest to the belly, is light-grey. The vent is pale-yellow. The entire back and tail are brownish-grey. The slightly downcurved slender bill is dark-grey. The legs and feet are also dark-grey. Juvenile White-spectacled Bulbuls have a paler head than adults and no crest yet. Twitcher's tip Comparing the photos below with those of White-eared Bulbuls, one can notice that the vent of the White-spectacled Bulbul has a paler hue of yellow.

Range, habitat Click here for information on habitat and range The overall distribution of this species can be assessed, and specific locations where birds have been spotted can be found, based on individual sighting reports submitted by birdwatchers to ebird.org . The global distribution of the White-spectacled Bulbul is available HERE . White-spectacled Bulbuls are sedentary. They populate the South coast of Asia Minor, the eastern coastline of the Mediterranean Sea, the southern Sinai peninsula, the lower valley of the river Nile river, the eastern coastline of the Red Sea, and the rest of the (near-)coastal fringe of the Arabian peninsula, plus some inland locations in Saudi Arabia. In Arabia, White-spectacled Bulbuls are found along a broad (near-)coastal strip through western Saudi Arabia, Yemen and into southern Oman. They are also residents along the North coast of Oman. We have seen White-spectacled Bulbuls in an arboretum, where they preferably stayed in flowering trees and also in dense shrubs.

Sightings Click here for sighting information White-spectacled Bulbuls are permanent residents on the Campus of Sultan Qaboos University, near Muscat, where we saw them regularly in the time frame August 2009 - May 2010.

Although it is not nice to peek up somebody's back side, this ventral view shows very clearly why this species was called the "Yellow-vented Bulbul" until the superspecies was split up and that name given to another species...

Bulbuls are the only bird genus known to us that will devour whole flowers. Below an example of a White-spectacled Bulbul is shown, but the same behaviour has also been observed in White-eared Bulbuls.
