Trilling gnatwrens build a deep cup nest very low in a small plant or sapling. The two white eggs are incubated by both parents for 16–17 days to hatching, with a further 11–12 days to fledging. Feeding Trilling gnatwrens forage actively in vegetation, eating mainly insects, insect eggs and spiders. They usually occur in pairs or family groups.
