Assessing the role of conspecific attraction in habitat resotration for Henslow's Sparrows in Iowa


September 2008 - June 2010


Examine the role of social cues, such as conspecific calls and attraction, in the habitat selection decisions of Henslow's Sparrows by answering the following questions: (1) can Henslow's sparrows be attracted to previously unoccupied restored habitat using conspecific call playbacks? (2) do the vegetation characteristics (structure and composition) of our experimental plots differ from control plots in our study area?
