Common Nighthawk (Chordeiles minor), a State Special Concern bird, can be found throughout Wisconsin but is most common in dry, sandy, prairie and barrens landscapes, along river systems, and in urban areas. They hunt on the wing for aerial insects such as caddisflies, mayflies, wasps, moths, and beetles during late evenings and early mornings. They nest in a variety of habitats including forest clearings, dry grasslands and barrens, gravel bars, cultivated fields, and on flat gravel roofs. The recommended avoidance period is May 20 - August 5.
