Yes it is. This whole categorization changed in 1989 when the U.S.
finally(!) became a signatory to the Berne Convention on Copyrights.
I don't know the exact nuances of the changes, but the "born
copyrighted" presumption now applies in the U.S., too. See the
last two paragraphs of the "History of copyright" section of
<http://en.wikipedia.org/wiki/Copyright>, and also the second
paragraph of the section on "Obtaining and enforcing copyright":

    In the United States, copyright has relatively recently been
    made automatic (in the style of the Berne Convention), which
    has had the effect of making it appear to be more like a property
    right. Thus, as with property, a copyright need not be granted
    or obtained through official registration with any Government
    Office. Once an idea has been reduced to tangible form, for
    example by securing it in a fixed medium (such as a drawing,
    sheet music, photograph, a videotape or a letter), the copyright
    holder is entitled to enforce his or her exclusive rights.

Though it goes on to say that registration *before* any infringement
may increase the damages the copyright holder might be able to
recover in a lawsuit.
