Resumo


We present here six new cases of birds with aberrant coloring in the state of Rio Grande do Sul, Brazil. Records were made via non-systematized field activities. We suggested Progressive Greying in Zenaida auriculata, Turdus rufiventris, Leptasthenura setaria, Molothrus bonariensis and for Sporophila collaris a case of Dilution – pastel. The study contributes with new informations about chromatic anomalies in birds’ plumages in Southern Brazil, since these cases must be divulged in specialized literature.
