POSSIBLE PHYLOGENETIC SIGNIFICANCE OF TAIL MOLT

  It might just be mentioned that a surprising number of my finches seem to have lost all their tail feathers at the same time.  Including:
       1 adult male Volatinia
       1 adult male yellow-faced Grassquit
       1 young female Sporophila aurita
       1 young female and 1 adult male S. nigricollis

Transcription Notes:
symbols: circle with an arrow pointing to the upper right = male, circle with a cross below it is female. -@raferrante
