The article presents the results of the raptor migration count at Eagle Valley Nature Preserve in Southwest Wisconsin along the Mississippi River bluffs from September 5 - November 7, 2010. It notes that the count produced the lowest tally since 1994, when full-time counts in the area started, a dismal record which the participants attributed to the inactive weather and to their shortened standardized count due to logistical and scheduling issues. Included are charts and tables showing data from the 1994-2010 study on raptor migration at Eagle Valley. |
