The subspecies of the ruddy woodcreeper are found thus:<p>The ruddy woodcreeper inhabits a variety of forest landscapes including lowland deciduous forest, rainforest, cloudforest, and gallery forest. It favors the interior of mature primary and secondary forest but also occurs at their edges, in younger secondary forest, and in semi-open areas with some trees. It is generally a bird of lowlands and foothills. At the northernmost edge of its range it occurs at elevations between 1,300 and 1,550 m (4,300 and 5,100 ft). In northern Central America it occurs as high as 1,650 m (5,400 ft) but is most common between 300 and 1,200 m (1,000 and 3,900 ft). In Costa Rica it mostly occurs between 500 and 1,200 m (1,600 and 3,900 ft) and in Panama between 300 and 900 m (1,000 and 3,000 ft). It is typically below 1,500 m (4,900 ft) in Colombia and below 450 m (1,500 ft) in Venezuela.
