Transient male PRB can have a distinct warmer wash to the breast and nape area, not something I've noted on RB, also much whiter on the underparts, with very little, to no streaking in evidence. One other feature which caught my eye was the tendency for the white area between the malar stripe and the crown to be somewhat wider on PRB than on RB. As stand alone features they probably wouldn't stack up...but when added to smaller size, contrasting white/pale rump area and upperpart cosmetics you end up with something that deserves more scrutiny.</blockquote>
