Black Bulbul. Tai Po Kau Nature Reserve 15 February 2023

These pictures had been taken by AJP two weeks in the past in Tai Po Kau reserve in Hong Kong. Since there have been heaps it must be assumed this was an irruption yr. Lately small numbers could also be seen in Tai Po Kau however sometimes there’s a enormous inflow from the north in winter; different years there are none to be discovered. Throughout an irruption Black Bulbuls could be seen all through Hong Kong.

I can bear in mind the thrill of seeing Black Bulbuls for the primary time—within the College of Hong Kong compound. That was in February-March 1967. The Chook Report for that yr famous:

The early a part of the yr produced what was most likely the largest irruption of this species in Hong Kong ever recorded.

The primary had been seen on 7 January 1967 however flocks of as much as greater than 90 had been seen in February. They stayed till properly into March with the final reported sighting on 25 March.

Within the college compound, earlier than it was ruined by over-development, it was comparatively simple to get an excellent view. The tops of the bushes the place they had been residing reached the extent of a footpath by the library.

In these days the Black Bulbul residing in Hong Kong was thought to be a subspecies of Hypsipetes madagascariensis. Now it thought-about a full species, Hypsipetes leucocephalus, one described by Johan Friedrich Gmelin in 1789. Solely absolutely grownup birds have s utterly white head.
