The streamside bird monitoring protocol is implemented in seven ERMN parks (all parks except Upper Delaware Scenic and Recreational River [SRR] and Johnstown Flood National Memorial [NMem]). Sixty-six sampling sites were established throughout these seven ERMN parks. Each sampling site and any associated point count stations are visited two times per year between May and July. During each visit, an observer traverses the stream reach twice (i.e., upstream and downstream), stopping at each point count station to conduct 10-minute point counts and associated data collection. Each time the reach is traversed is referred to as a “pass.” By waiting 10 minutes between passes, each of these passes is considered an independent sample; therefore, each site is sampled four times per year (two visits per year and two passes per visit). This report summarizes the first six years (2007–2012) of protocol implementation and provides an overview of the methods, sites, and effort thus far, as well as summaries of the species detected and total number of detections (as an index of abundance). This report also calculates Bird Community Index (BCI; an index of biotic integrity) at the park- and stream-reach scale and provides estimates of Louisiana waterthrush (Parkesia motacilla) occupancy at the stream-reach scale. The Louisiana waterthrush is an obligate riparian breeder that is particularly well sampled by this protocol and has been argued to be an indicator species of riparian ecological condition.
