Rallus obsoletus
The Ridgway's Rail (Rallus obsoletus) is a secretive and elusive medium-sized marsh bird, measuring 30-40 cm (12-16 in) in length with a wingspan of 46-51 cm (18-20 in).

Ridgway's Rails are crepuscular and nocturnal, most active at dawn, dusk, and during high tides when foraging opportunities increase. They move stealthily through dense vegetation, often running rather than flying when disturbed, and can swim or dive for short distances. Highly territorial, espec...
