The Milan Bottoms is located along the Mississippi River in Rock Island County, Illinois. It lies just south of the I-280 Bridge on the south edge of the Quad Cities; it is bordered by U.S. Highway 92 on the south end, and by the town of Andalusia on the west end. The U.S. Army Corps of Engineers owns about 1200 acres of the main habitat. A variety of private individuals own some of the surrounding habitats.

Ornithological Summary

The following is a summary of bird observations collected during the past 14 years in the Milan Bottoms Study Area, which includes:

One of the largest heron and waterbird rookeries along the Upper Mississippi River with over 240 active nests including Great Blue Herons, Green Herons, Yellow-crowned Night Herons, and Double-crested Cormorants.

An active Bald Eagle nest which successfully fledged young in 2006.

A major wintering night roost for over 500 Bald Eagles. This site may indeed be one of the most heavily used Bald Eagle night roosts in the Upper Midwest. Research conducted in the winter of 05 & 06 by Kelly McKay and the USCOE documented over 500 eagles using this area as a night roost.

A record from 1992 through 2006 of multiple nesting sites for Red-shouldered Hawks.

A similarly long record of Cerulean Warblers during the breeding season.

Perhaps one of the most significant concentrations of nesting Prothonotary Warblers in the Upper Midwest.

According to Scott Robinson, a prominent avian biologist who has helped to analyze some of the bird data from the Milan Bottoms, the density of nesting and wintering Brown Creepers in the Milan Bottoms is highest of any known site in Illinois.

An active Turkey Vulture night roosting site (usually between 60 & 80 individuals) which is active from April through October.

Other species of interest known to nest within the Milan Bottoms include Pileated Woodpecker, Northern Parula, Carolina Wren and some notably high numbers of Red-headed Woodpeckers.

This site was chosen as an IBA because it met the criteria for Herons and wintering Bald Eagles.
