Grassland bird nesting ecology: video samples of behavior: 2nd edition

We provide video clips related to the nesting ecology of grassland birds. Each video has a brief description in the included catalog. These videos are supplemental material for scientific publications by the authors, and constitute a subset of videos collected from 2006-2014 as part of research on the nesting ecology of grassland birds conducted in Wisconsin, USA, and Alberta, Canada.Grassland birds are ground nesters that construct nests that are generally well camouflaged by surrounding vegetation. Consequently, their nesting ecology has been more difficult to observe than the ecology of cavity- or shrub-nesting birds. Using video cameras to record behavior of adults, nestlings, and other actors functions to improve our understanding of nesting ecology. This, in turn, improves our management insights and facilitates placing the nesting ecology of grassland birds in the broader context of the nesting ecology of birds generally.For the 2nd edition all of the videos are available as MP4 files, three videos were added, and descriptions were updated to replace "flight" phrasing with "wing-assisted". This reflects the fact that nestling grassland birds cannot engage in sustained flight, but can (when old enough) coordinate their use of wings and legs. This coordination permits the young to leverage wing-generated lift to assist leg-generated thrust to move farther than use of legs alone would allow. Wing-assisted locomotion reaches its peak with "short flight", wherein the young birds are flying for short distances (although their development has not progressed enough to allow sustained flight).
