From an alternative spelling: This is a redirect from a title with an alternative spelling of estrus. Pages that link to this redirect may be updated to link directly to the target page if that results in an improvement of the text. Do not "fix" such links if they are not broken. Also, these links should not be replaced with piped links.
If Estrus is retargeted or is expanded into a separate article, template, or other project page, this redirect will be recategorized to be updated.
To a section: This is a redirect from a topic that does not have its own page to a section of a page on the subject. For redirects to embedded anchors on a page, use {{R to anchor}}instead.
When appropriate, protection levels are automatically sensed, described and categorized.
