| Popis: | Wetlands under moist-soil management are managed using disturbance and water regimes to enhance vegetative production during the growing season and flooded in the fall to accommodate waterfowl; however, little research has investigated the use of such wetlands by secretive marsh birds. Our objective was to determine patterns of habitat use by bitterns (Ardeidae) and rails (Rallidae), “secretive marsh birds,” in relation to habitat structure within and among moist-soil wetlands during spring and fall migration in Kansas. We used call-playback (spring) and flush counts (fall) to survey birds. Of our target species, only American Bittern (Botaurus lentiginosus), Least Bittern (Ixobrychus exilis), Virginia Rail (Rallus limicola), and Sora (Porzana carolina) were detected. Abundances varied markedly between years of our study (2014 and 2015), perhaps because of annual variation in precipitation or drawdown timings. In spring, Sora were found in wetland units with relatively tall Polygonum. No other si... |
