Black Rail, Peter LaTourrette

The tiny, red-eyed Black Rail is only the size of a sparrow and is the smallest rail in North America. Like its South American relative, the Junin Rail, it is as elusive as a mouse, skulking and scurrying under the cover of dense marsh vegetation and rarely taking flight.

Despite their small size, Black Rails are fiercely territorial during the mating season and call loudly and frequently with a distinctive three-noted "kickee-doo."

The Black Rail population has been declining steeply over the last 10-20 years, likely due to increasing development in coastal areas, which has caused habitat loss and degradation of suitable breeding areas.

They are also vulnerable to nest predators such as raccoons, cats, and rats. Invasive plants, such as Phragmites, crowd out native marsh vegetation and result in a further loss of habitat. The biggest threat to Black Rail may be climate change; sea level rise could quickly swamp its low-lying habitat.

The Black Rail was proposed for listing under the Endangered Species Act (ESA) in October 2018 and finally listed as Threatened in October 2020.
