Diversity and activity of bird fauna in ephemeral river-created habitats in Amazonia

Seasonal changes in runoff and inundation create river-habitats that are considered key to the diversity of Amazonian bird species. However, studies on avifauna different riverine habitats remain scarce. We used camera traps survey river-created along 39 km river eastern Brazilian Amazon. examined number species detected composition islands margin banks, evaluated species–area relationships these two habitats, if most abundant have differences activity pattern between habitats. Cameras recorded 21 from 13 families (Accipitridae, Ardeidae, Bucconidae, Caprimulgidae, Cathartidae, Columbidae, Cracidae, Hirundinidae, Icteridae, Scolopacidae, Thraupidae, Threskiornithidae, Tyrannidae). Species did not differ habitat types but we found a discernible area effect, explaining as much 84% across island sites. Overlaps were high types, peaks for Molothrus oryzivorus Pitangus sulphuratus while examining banks. River-created relevant must be increased better understand their value
