     (The Blue & Oranges might be anything. Perhaps the same as the Fire-bellies. Perhaps active nuclear or attendants)

VI. The PR is the great problem: Certainly functioning as passive nuclear here and now. (The fact that its song is so similar to those of the diglossini might even suggest that it is highly specialized, or at least specializing, to enhance its passive nuclear capabilities.) But comparative data would suggest that it was once an attendant species or (possibly subsequently) an active nuclear species. Its position here is probably very similar to what the position of the Yellow-thigh would be in Chiriqui if the BCBT dropped out of the mixed montane association. It would be interesting to see if the PR reverted to another status, here, if a more typical passive nuclear (ie. "auto"-gregarious) species appeared.
     (The status of the PL's here is still quite obscure.)
