» Life History
Species is associated with dense emergent riparian vegetation. Requires wet substrate (mudflat, sandbar) with dense herbaceous or woody vegetation for nesting and foraging. Fresh-water marshes dominated by cattail or bulrush are preferred habitat. Early successional marshes with little residual vegetation may be preferred as well. Habitat should be in a mosaic of vegetated areas interspersed with shallow (less than 12") open water areas. Minimum size of suitable habitats is unclear, but have been found in areas as small as 2-3 acres depending on the quality of the mosaic. Typically found below 4,500 feet of elevation.
Primarily crayfish, with small fish, frogs, and aquatic invertebrates also taken.
Movement / Home Range
Most individuals do not migrate, but have minor seasonal changes in their activity areas. Juveniles do disperse to nearby habitats. The recent extension of the range north along the lower Colorado River implies that rails are capable of longer distance movements, although the presence of scattered habitat patches for resting is likely important. Seasonal availability of food may be important factor in the need to migrate greater distances.
Rails establish pair bonds and territories in March-May, with nesting in May through June. One clutch is born per year. Juveniles are ready to breed the spring following their birth.
Important threats: loss of marsh habitat through channelization, dredging/filling activities, decline in quality of marsh habitat due to build-up residual vegetation (dead stems and leaves of cattails or bulrush) that clogs movement through the vegetation, and selenium contamination of the prey base.
