Bird response to enhanced habitat diversity

Since 2006, we have been examining bird density and nest success in the Spring Run Wetland complex in NE Iowa.  Dave Otis and I supervise Jen Vogel, a Ph.D. student.  The latest progress report is available here.  


Bird survey of Iowa State Preserves

Many of Iowa's prairie remnants are protected as Iowa State Preserves.  Some have being buffered from the agricultural matrix by the addition of reconstructed prairie.  Abel Robles, a M.S. student, is surveying birds on these Preserves to document bird use, especially use by area-sensitive species.  The latest progress report is available here.  


Bird response to landscape enhancement for grassland birds in southern Iowa

Since 2000 I have conducted annual roadside surveys in a pair of landscapes in southern Iowa.  One of these areas contains the Kellerton Bird Conservation Area, where woody vegetation is being removed and prairies are being reconstructed.  In 2010, I will compare trends of bird populations in the two areas, in cooperation with a similar effort being conducted in Missouri by Brad Jacobs.
