Passive acoustic monitoring allows the rapid assessment of sonorous species distribution and behavior over wide scales of time and space, as well as geophysical and human-made sounds, composing a soundscape. This work analyses a bird assemblage, its species activity periods and their relation to soundscape characteristics and events. Automated recorders were deployed on 9 sites in a south Brazilian Rain Forest conservation unit from 2006’s spring to 2007’s winter. Species singing activity was related with daily patterns and other soundscape components through ANOVA analysis. A total of 7776 1-minute sound samples were obtained, from which we identified 98 bird species, along with 14 anuran species, 41 insect phonotypes, 4 geophony categories, and human noise. 30 bird species surpassed n ≥ 100 samples, from which we obtained circadian and seasonal patterns and relationships of individual species singing behavior under other phonic sources presences.
