Wrens are tiny birds with reddish-brown upperparts with fine brown bars and darker brown on their wings. Their underparts are pale brown with heavily streaked flanks and belly. They have a short rounded tail which is chestnut coloured with dark brown streaks.
Wrens have darker heads and nape with a pale supercilium from the base of the bill to behind the eye. They have long, slender bills with a black upper mandible and a yellow lower mandible. Eyes are dark brown and legs and feet are pale brown.
Adult male and female wrens look similar while juveniles are redder with a streaked head and nape and darker underparts.
Male wrens build 3 or 4 nests from sticks and moss of which the female chooses one which she then helps to line with feathers and hair.
Whens lay 4-7 white eggs with brown spots that she incubates alone for 12-10 days. Chicks fledge after 3 weeks and both parents feed them for a further 40 days.
Wrens diet consists of insects and spiders as well as small vertebrates such as tadpoles and small fishes. They will also eat seeds and berries.
