The hyacinth macaw (Anodorhynchus hyacinthinus) is a parrot in the family Psittacidae, native to central and eastern South America. With a length of around 1 metre (3 feet), it is longer than any other species of parrot. It is also the largest macaw and the largest flying parrot species. The hyacinth macaw mostly nests in manduvi trees; these trees rely on the toco toucan for the majority of their distribution of seeds, but that bird also feeds on a sizeable proportion of the hyacinth macaw's eggs. Habitat loss and the trapping of wild birds for the pet trade have taken a heavy toll on their population in the wild, so the species is classified as vulnerable on the IUCN Red List. This hyacinth macaw eating a nut was photographed by the Rio Negro, a river in the Pantanal in southwestern Brazil.Photograph credit: Charles J. Sharp

Transclusion vs. Substitution

There are two main ways to use templates on articles:

1. Transclusion – also called "inclusion", and accomplished by using {{Template Name}}
2. Substitution – notated like this {{subst:Template Name}}

Transclusion will include the content of Template Name on the fly whenever the article is loaded, while the latter will permanently insert the content of the template into the article. With substitution, even if the template content is modified at a later date, the article's content will not change.

Substitution is the preferred method for long-term, permanent notices because it is less confusing, and it even helps to lighten the load on the database. Substitution has the further advantage in that a template's content may be de-linked from any associated category or slightly modified to suit the circumstances, such as when the template is used on a talk page. Transclusion is preferred for displaying material that is normally updated, that way, all the places it appears are updated in a single operation.
