Abstract

In context of the prolonged invasion of smooth cordgrass Spartina alterniflora, numerous native birds have progressively adapted to this invaded plant. Not only certain non-specialist birds demonstrate an ability to inhabit and utilize smooth cordgrass, but a subset of specialist birds is also detected in the habitat as well. In this study, we investigate a previously undocumented Rallidae species, the slaty-breasted rail Lewinia striata, living in smooth cordgrass. These rails exhibit a significant reliance on the invaded vegetative community during their breeding season, engaging in foraging, vocalization, and even successful reproduction within the smooth cordgrass. These findings underscore the likelihood that amidst the ongoing decline of natural wetlands, those avian species with a profound dependence on marsh ecosystems may be compelled to adopt invasive smooth cordgrass as a vital refuge. Such a transition is poised to impact their distribution, foraging, and reproduction. With the backdrop of large-scale removal of smooth cordgrass on the China coast, the disappearance of smooth cordgrass may harm the population of these birds. Further dedicated investigations and tracking of more individuals are needed to understand the specific ecological impact on slaty-breasted rail.
