Taxonomy:

Sporophila pileata

Borda do Mato, eastern São Paulo, Brazil

Until recently considered conspecific with S. bouvreuil, but detailed mapping has demonstrated a considerable area of sympatry#R while subsequent genetic analysis has determined that bouvreuil is probably sister to the “S capuchino” clade within which present species sits#R; intriguingly, however, no obvious vocal differences have been identified in available recordings, although more recent study indicates such differences while confirming a modest genetic distinctiveness in bouvreuil but not between present species and four other “capuchinos” investigated (see S. hypoxantha). Monotypic.

Distribution:

S Brazil (E Mato Grosso, Goiás and SW Minas Gerais) S through E Paraguay to NE Argentina (Corrientes and Misiones)#R, locally to N Uruguay; also recorded in Bolivia (Santa Cruz).
