Geographic Range

It has been confirmed to occur in Colombia, Costa Rica, Nicaragua, and Panama, and may also be present in Honduras.

Habitat Types

Its natural habitats include subtropical or tropical moist lowland forests, intermittent freshwater marshes, pastureland, plantations, rural gardens, and urban areas.

Elevation Range

It can be found at elevations up to 600 meters above sea level.
