Las Palomas Marsh, a cow pasture when Caballo Lake is low and a marsh when the lake is high, is a 40-acre livestock exclosure located south of Truth or Consequences. When marshy, it offers good shore and marsh birding. Desert scrub species and winter sparrows are numerous. The cottonwoods at the south end may be productive in migration. You may walk to the Rio Grande from here.

Las Palomas Marsh is a natural area that is protected and managed for aquatic and riparian habitats. Depending on water levels, the area offers good shore and marsh birding; desert scrub bird species are numerous in the winter. You can also walk to the Rio Grande/Caballo Reservoir (depending on water levels) from the marsh area.
