The geographical ranges of many bird species are neither uniform nor continuous. Species
that are common in some regions may be rare in others, or their status of occurrence
may be uncertain. Here, we present the first documented record of Azure Gallinule
(Porphyrio flavirostris) as well as details and discussion on the distribution and
status of previous records of the Least Bittern (Ixobrychus exilis), Paint-billed
Crake (Neocrex erythrops), and Plain-breasted Ground-dove (Columbina minuta) in the
Brazilian state of Acre. While all these species have relatively wide ranges, little
is known of their distribution in the southwestern Amazon basin.
