Unexpected things about Goldcrest Bird

The goldcrest (Regulus regulus) is a very little kinglet-like passerine bird. It gets its English and scientific names from its colorful golden crest feathers, as well as being known as the "king of the birds" in European mythology. R. regulus is the scientific name for a king or knight. 

Greenish upperparts, whitish underparts, and two white wingbars distinguish this kinglet. It has a simple face with black irises and a colorful head crest, which is orange and yellow in the male and yellow in the female and shown during breeding. Although it looks similar to the common firecrest, which has a similar European range, the latter's bronze shoulders and bold facial pattern distinguish it. The song is a series of high thin notes that are somewhat higher in pitch than their relative. Canary Island birds are currently divided into two subspecies of the goldcrest, but they were formerly thought to be a subspecies of the firecrest or a new species, Regulus teneriffae.

The goldcrest builds its compact, three-layered nest on a tree limb in coniferous woods and gardens. The female alone incubates ten to twelve eggs, and both parents feed the babies; second broods are usual. This kinglet is constantly on the move in search of insects to eat, and it is frequently seen with flocks of tits in the winter. It may be preyed upon by birds of prey or carry parasites, but because of its broad range and population, it is not thought to pose a severe conservation threat.
