Novas áreas de ocorrência de três Passeriformes no sul do Brasil

New sites for the distributional range of three Passeriformes in southern Brazil. The knowledge on bird distribution in southern Brazil is fairly satisfactory but new distributional data is added quite often. In the present work, we provide records of new sites in southern Brazil where three Passeriformes were unknown to occur — the Black-backed Water-tyrant (Fluvicola albiventer (Spix, 1825)), the Hooded Tanager (Nemosia pileata (Boddaert, 1783)) and the Bicolored Conebill (Conirostrum bicolor (Vieillot, 1809)) — the first two are also new records to Santa Catarina state. The record of the Black-backed Water-tyrant was made in the midst of a gap recognized so far in its distribution in southern Brazil, and the few data available do not allow any further conclusion on the implications of this register. The record of the Hooded Tanager, although maybe consequence of a wandering individual, suggests a current expansion of this species range. Finally, the records of the Bicolored Conebill represent a new southernmost distribution limit for the species. All birds recorded here were photographed.
