FIGURE 6. Box plot comparisons between measurements of the five groups of the Long-tailed Reed Finch Donacopspiza albifrons delimited here (see text). Boxes show the median line and the 25th and 75th percentiles; bars show the non-outlier range of variation. Sample sizes are: RP—Río de la Plata (25♂, 18♀); SB—Southern Brazil (9♂, 8♀); SU—Southeastern Brazil Uplands (8♂, 4♀); SH—Southeastern Brazil Highlands (10♂, 8♀); and LM—Llanos de Moxos (3♂, 1♀).
