The musk lorikeet (Glossopsitta concinna) is a lorikeet, now the only species in the genus Glossopsitta. It inhabits south-central/eastern Australia. The little lorikeet and the purple-crowned lorikeet were previously included in the genus. The musk lorikeet was first described by ornithologist George Shaw in 1790 as Psittacus concinnus, from a collection in the vicinity of Port Jackson in what is now Sydney. John Latham described it as Psittacus australis. Its specific epithet is the Latin concinna "elegant". Other common names include red-eared lorikeet, and green keet, and formerly a local Sydney indigenous term coolich. The names green leek and king parrot have been incorrectly applied to this species in the past.

The red-tailed comet (Sappho sparganurus) is a medium-sized hummingbird belonging to the family Trochilidae. It is the only species placed in the genus Sappho.

In computer programming, an anonymous function (function literal, lambda abstraction, lambda function, lambda expression or block) is a function definition that is not bound to an identifier. Anonymous functions are often arguments being passed to higher-order functions or used for constructing the result of a higher-order function that needs to return a function.If the function is only used once, or a limited number of times, an anonymous function may be syntactically lighter than using a named function. Anonymous functions are ubiquitous in functional programming languages and other languages with first-class functions, where they fulfil the same role for the function type as literals do for other data types. Anonymous functions originate in the work of Alonzo Church in his invention of the lambda calculus, in which all functions are anonymous, in 1936, before electronic computers. In several programming languages, anonymous functions are introduced using the keyword lambda, and anonymous functions are often referred to as lambdas or lambda abstractions. Anonymous functions have been a feature of programming languages since Lisp in 1958, and a growing number of modern programming languages support anonymous functions.
