The rufous gnateater (Conopophaga lineata) is a passerine bird of the gnateater family, Conopophagidae. It is found in forest understory and bushes in eastern Brazil from Rio Grande do Sul north to central Brazil. Its range also extends into eastern Paraguay and north-eastern Argentina and it has recently been recorded in Uruguay. It is often elusive and hard to see, but is commoner and less shy than other gnateaters.
