CSS CSS Basics (2014) Enhancing the Design With CSS Web Fonts with @font-face

Why are there 2 "src: " declarations in the @font-face code?

  src: url('../fonts/abolition-regular-webfont.eot');
  src: url('../fonts/abolition-regular-webfont.eot?#iefix') format('embedded-opentype'),
       url('../fonts/abolition-regular-webfont.woff') format('woff'),
       url('../fonts/abolition-regular-webfont.ttf') format('truetype');

Reading online reference material on this IE fix it says the browser will usually skip to the last src declaration, so why are there 2? Surely the first src can be omitted?

Someone might be able to answer this more in depth but that's just how the font declaration has to be. The first src is for IE9 and then the other browsers are supported in the second. You can possibly get away with the last one but if you're going to bother it's obviously best to cover all your bases.
