Byerlyetal_PointCountData

Point count results from restored and reference marsh on Raccoon and Whiskey Islands, Terrebonne Bay, Louisiana 2017–2018. We conducted five point counts in 2017 and four point counts in 2018. Point counts were conducted between roughly 0730 and 1300 at the same established points used for acoustic monitoring over two breeding seasons (April-July). When possible, two observers were dropped at opposite ends of the islands to maximize number of points surveyed at the earliest time possible.
Presence/absence was determined via passive counts, with
observer waiting 2 minutes and then conducting a 3-minute
count of all species seen or heard within 100m of each point. Flushed birds were counted within 100m of each point, as cryptic species are often only detectable when disturbed, and wading birds within plots often departed the site as the recorder approached. Flyovers were not counted.
