A black head (technically known as a comedo) is a yellowish, reddish (with white cap) or blackish bump or plug on a skin. It is caused by excess oils that have accumulated in the sebaceous gland's duct. Black heads are typically caused by excessive oil, make up and dirt.

BlackHead Surf Life Saving Club is situated in the southern corner of BlackHead Beach, Hallidays Point, midway between the major towns of Forster and Taree on the Mid North Coast of New South Wales, Australia.
BlackHead beach is approximately 1.3 kilometres in length and is extremely dynamic, with sand movement quiet noticeable in various sea conditions.
BlackHead is considered a relatively safe beach, though in the latter mentioned states can become extremely unpredictable with the ebb and flow of the tide or swell variations changing currents and forming rips in a matter of minutes.
Because the genes for red head color are sex-linked and one of these genes is required for the expression of yellow head coloration, a clear understanding of sex linkage is necessary to understand the inheritance of both red and yellow head traits.
It is simplest to describe the mechanism of Gouldian head color inheritance by referring to the flheaded bird as the normal state and noting the effect on the flheaded bird when it inherits one or more genes for red head or yellow head.
For a bird to be flheaded, it must carry the flhead gene on all its X chromosomes (1 for the hen, 2 for the cock).
