Whitehead's trogon (Harpactes whiteheadi) is a species of bird in the family Trogonidae. It is endemic to the island of Borneo, where it is an uncommon resident in primary mountain forest. One of Borneo's largest trogons, at 29 to 33 centimetres (11 to 13 inches) long, it is sexually dimorphic. The male is crimson on the head, nape, and underparts, with a black throat and grey chest; the rest of its upperparts are cinnamon-coloured. The female is similarly patterned, but cinnamon-brown where the male is scarlet. The species is primarily an insectivore, but also eats various plant materials, including fruits and seeds. Other than the timing of its breeding, typically between April and June, little is known about its breeding biology. It is classified as a near-threatened species, with population numbers thought to be declining and habitat loss a key threat. This male Whitehead's trogon was photographed perching on a branch near Mount Kinabalu in the Malaysian state of Sabah.

Nominative determinism is the hypothesis that people are drawn to professions that fit their name. The term was first used in the magazine New Scientist in 1994, after its humorous Feedback column mentioned a book on polar explorations by Daniel Snowman and an article on urology by researchers named Splatt and Weedon. The hypothesis had been suggested by psychologist Carl Jung, citing as an example Sigmund Freud (German for 'joy'), who studied pleasure. A few recent empirical studies have indicated that certain professions are disproportionately represented by people with appropriate surnames, though the methods of these studies have been challenged. One explanation for nominative determinism is the theory of implicit egotism, which states that humans have an unconscious preference for things they associate with themselves. An alternative explanation is genetic: an ancestor might have been named Smith or Taylor according to their occupation, and the genes they passed down might correlate to aptitudes for those professions.
