Diet:
They eat insects and small spiders, which they find in dense undergrowths.

Breeding:
Long-billed gnatwrens breed in April-June. The nest is a deep cup made of plant fibres and placed in a small plant, sapling or vine, near the ground. The female lays 2 white eggs with reddish-brown spots, which are incubated by both parents for 16-17 days. The chicks fledge 11-12 days after hatching.

Conservation:
IUCN status – LC (Least Concern)
This species has a very large breeding range and a global population estimated at 5-50 million individuals. The population is suspected to be in decline owing to ongoing habitat destruction and fragmentation, but it is not considered threatened at present.
