Avifauna occurrence data from a longitudinal experiment in human-modified Amazonian forests affected by the 2015-16 El Niño drought and associated fires

This data set includes longitudinal occurrence of bird species at 36 forest plots – half of which burned during the 2015-16 El Niño drought – distributed across a gradient of prior human disturbance in the Brazilian Amazon. Data was collected in 2010 and 2016 (around 6 years before, and one year after the 2015-16 El Niño, respectively) as part of the projects ‘Assessing ENSO-induced Fire Impacts in tropical Rainforest Ecosystems’ (AFIRE) and ‘Biodiversity and Ecosystem Functioning in degraded and recovering Amazonian and Atlantic Forests’ (ECOFOR), within the NERC Human-Modified Tropical Forest (HTMF) programme.

Provenance & quality

In 2010 and 2016, bird sampling occurred along 300-m forest plots at the same three sampling points (0, 150 and 300m). All bird species seen or heard were recorded through two repetitions of three 15-min, 75-m fixed-width point counts per plot. Surveys were undertaken between 15 min before dawn and 09:30, only in days without persistent rain and/or strong winds. Point counts were recorded with solid-state recorders. Seasonal and temporal variation in bird vocal activity were minimized by systematically rotating repetitions between catchments and study plots. Datasets were processed by tropical bird specialists, and were then transferred to the programme data manager of the HMTF programme.
