image of Common MoorhenThe Common Moorhen breeds in freshwater marshes vegetated with cattails (Typha spp.), bulrushes (Scirpus spp.) and willows (Salix spp.). They do not require a large marsh and may reside in small patches of emergent vegetation at the edge of lakes or rivers (Terres 1987). Their nests, which are usually anchored in vegetation at the water's surface, are similar in appearance to an American Coot's nest but smaller in diameter (Fredrickson 1971).

Code Frequency

Common Moorhens are extremely hard to locate because their habitat is difficult to survey and they nest in dense emergent vegetation. Breeding evidence for the Common Moorhen was found in only one block during the seven-year Atlas Project.

Distribution

An individual in breeding habitat sighted at the Ted Shanks Conservation Area in Pike County may have nested undetected and the species may have been present but undetected in other marshlands.
