Abstract

Field records are critical to understand the bird species distribution in ecological and evolutionary contexts, especially in regions with high species diversity such as the Amazon Basin. Here we describe notable bird species records in areas with difficult access, sites monitored from long-term and human-impacted regions in the central and northwestern portions of the Amazon Basin. We present information for 35 selected species, including birds rarely observed in nature (e.g. Crypturelus duidae, Ammonastes pelzelni, Cyanocorax heilprini), species common in other biomes but rare in the Amazon (e.g. Vanellus chilensis, Elaenia flavogaster), and species apparently reported for the first time for the Amazonas state, Brazil (e.g. Hydropsalis roraimae, Myrmeciza longipes). Our records suggest recent colonization of central Amazon by some species, likely favored by the increasing environmental degradation in the region. In addition, records of species previously not reported for Amazonas state reinforce the relevance of inventories in poorly sampled regions. These bird records illustrates how biological inventories and long-term monitoring are complementary strategies for a better understand of distribution and dynamics of the Amazon avifauna. (AU)
