The first Breeding Bird Atlas publication, published in 1996, provided in-depth species
accounts of Iowa's breeding birds. It is a must read for anyone interested in avian
ecology of the state. This sequel uses the data from the latest atlas project
to update what we know today. Enjoy comparing the records of different
species from BBA I to BBA II. Select a species and get started. Click on a map pin to
see the location details. For species with many records and a cluttered map, zoom
