We sampled bird communities along three cross-floodplain transects per site. We established two stations per transect (six per site), and at each station, we counted birds seen and heard using 50-m fixed radius, 15-min point-count surveys. We surveyed during winter (January), spring (April), summer (June), and fall (October) 2013. One trained observer visited each station, and we reversed the order in which stations were surveyed between visits. Surveys were conducted under similar environmental conditions (i.e. no rain and wind from 0 to 3 on Beaufort scale) and were completed within 4?h of sunrise. We began surveys immediately upon arrival at the station and included birds flushed by the observer upon arrival. Observer recorded species on the basis of Sibley (2000) and classified according to Pyle and DeSante (2012). Bird minimum abundance (hereafter, abundance) was calculated as the greatest number of individuals of each species seen or heard at either station along each transect, per season. Because we did not individually mark animals, this method (of minimum abundance) conservatively estimated abundance and ensured that we did not count individuals twice.Citation(s)
