What's the menu area near the clock called? What is the part of the menu bar called with the time machine, bluetooth, wifi, volume and battery icons called? (Near the clock)

I wanted to search how to remove unused icons from it (like timemachine)



Edit: How can I get rid of this icon in my menu bar? How can I put the icon back?

I'd still like to know what it's called, like the system tray on Windows.
These are called menu extras. 

They are different from status bar items (which are usually used in other apps) in that you can hold command and drag them around. 

Each of these can be turned on and off with a checkbox in System Preferences (the Bluetooth one can be toggled in Bluetooth preferences, etc.)
