N2 - We examined long-term responses of an Amazonian bird assemblage to wildfire disturbance, investigating how understory birds reacted to forest regeneration 1, 3, and 10years after a widespread fire event. The bird community was sampled along the Arapiuns and Maro river catchments in central Brazilian Amazonia. Sampling took place in 1998, 2000, and 2008 using mist-nets in eight plots (four burned, four unburned sites). Species richness did not change significantly in unburned sites. In burned sites, however, we found significantly lower richness in 1998, higher richness in 2000, and similar richness in 2008.
