Former Cornell undergrad Graham Montgomery and I just published our paper (open-access! thanks Condor!) describing the results of playback experiments we conducted in 2014 -- Swainson's Thrushes in the Adirondacks exhibit asymmetric interspecific aggression towards threatened high elevation Bicknell's Thrushes. This is consistent with the possibility that Swainson's Thrushes are behaviorally dominant, and we suggest Bicknell's Thrushes, already limited to mountaintop environments, may be threatened both by climate change and by interspecific competition (and the interaction between these factors). Read the great press release on the Condor blog!
