The Eurasian Wren (Troglodytes troglodytes) is a small passerine song bird in the Troglodytidae family.
The Eurasian Wren is rufous-brown with a paler, greyer underbelly. Its wings and tail are barred with darker brown and grey. However, it can vary in colour. It has short, rounded wings. Its beak is dark-brown. Its legs are pale brown.
It grows to 9-11 centimetres (3-4 inches) tall.
It is native to Europe, Asia, and Africa. It prefers mountainous regions and cooler habitats. It is also seen in parks and gardens.
It is migratory only in the northern parts of its range.
It it territorial and will chase away other birds from its territory.
It is an insectivore, eating insects. It also eats arachnids, such as spiders and scorpions. It ‘hop-searches’ for food.
The male builds several nests, often six or seven, in a hole in a tree, rock, or building. The female chooses one. When the female chooses one, the male then lines it with grass, moss, or leaves. The female lays 5-8 speckled eggs, which hatch after about 14 days.
Newborn chicks are blind and featherless, which is known as altricial. Their eyes open after 5-6 days, and they are fully feathered by 10 days. Fledglings are able to feed themselves after 40 days, but remain in the family group for a year or more before moving to another group.
