Research Interests

My research interests centre on the ecology of grassland birds and factors that influence habitat selection and demography.  This ranges from applied studies examining the influence of agricultural management regimes on grassland birds to the effects of energy development.  My interests also extend to determining how settling patterns and demographic processes of grassland species vary according to different spatial scales.  Relatively little research has been conducted on grassland birds in the northern mixed-grass prairie, thus research topics are only limited by one's imagination. Furthermore, grassland birds are in dire need of basic research on their natural history and applied research that allows an understanding of factors causing widespread population declines so that land managers and conservation agencies can make informed decisions.  In my opinion, this creates a wonderful opportunity for graduate students to make a significant and very satisfying contribution to both science and conservation.

Bird Sculpture

When not studying birds from a scientific perspective, you can find me studying them as an artist. It is hard not to be inspired by the beauty and behaviour of these magnificent creatures when spending time in the field conducting scientific investigations.
