It seems that at least one photo (01-039-005) is
instructive in terms of tail construction.  Cooper's
two outermost tail feathers are significantly shorter
than the inner tail feathers.  This picture with the
bird looking back over it's shoulder gives a clear
view of the left outermost tail feather; significantly
shorter than any others.  The right tail feathers
"appear" significantly shorter, but the left one is
more apparent.  Along with Alvaro's point regarding
the relative thickness of the white terminal tail
band, this bird adds up to be a juvenile cooper's
hawk.
