Ann Barker Library

A searchable library of past issues of Iowa Bird Life from 1931 - 2012.   This great resource was made possible by a bequest from former president Ann Barker and was created as a memorial to her.

Iowa Breeding Bird Atlas

The second atlas project is capturing data on breeding birds from 2008 through 2012.  Iowa birders enter their data in this application and everyone can follow the progress in real time. Be sure to check out the distribution changes since the first project in 1985 - 1990 with the overlay map.

Iowa's Important Bird Areas

In partnership with Iowa Audubon, IOU members have nominated and then provided data to support designations of IBAs in Iowa.  Continued monitoring of these areas are supported by data entered into the IOU seasonal field reports.
