In part because of the exceptionally wide range of habitats the Wren breeds and survives in, it is has the accolade of being the most common breeding bird in the UK. It is small bird with a somewhat dumpy appearance, and with its upturned tail, thin long bill, brown plumage and white eye stripe, it cannot be mistaken for any other bird. Its astonishingly loud song is also a great giveaway to its presence.

Wren nesting and breeding habits

The Wren’s nest is a beautiful and delicate dome construction consisting of moss, plant material, lichen, leaves and feathers, and located in a hollow or crevice in a tree, wall, bank or rock face. Other locations include behind climbing plants such as ivy, plus nest boxes will sometimes be used. The male builds the main structure with the female then lining it with feathers, though the male may build several nests with the female then choosing the right one. However, all the nests the male builds may be taken by females, as the species is polygamous and therefore the male bird may mate with several females – all of which can go on to successfully have young. Incubation is by the female only of the 5-6 eggs, with two broods per season normal. Both parents feed the young.

Wren diet and food

Insects, insect larvae and spiders make up the Wren’s diet, with a limited amount of small seeds also eaten. In the garden, Wrens will not normally feed on food put out such as seeds and suet, however, live mealworms are likely to be taken and probably readily so in the breeding season.

Wren history and population trends

The UK population trend for the Wren, especially in England, has been one of moderate increase. Overall though, the population is seen as stable – though huge population crashes occur during harsh winters. When this happens though, the species is usually able to quickly bounce back due to its prolific breeding habits (i.e. polygamous, large brood size, 2 broods per season, massively varied habitats for nesting).

Behaviour traits of Wrens

The Wren’s behaviour can be highly entertaining to observe, as it flits from once place to another – its short little wings a blur as it goes – in search of food, and with ability to effortlessly manoeuvre itself under and into the tightest of nooks and crannies. Despite being highly territorial, in the winter months and especially in very cold weather, Wrens will roost together in enclosed spaces and there may be several dozen birds squashed together to keep warm.

Widespread across the whole of the UK and even, for example, in remote island locations in Scotland



The Wren occurs in an especially varied range of habitats, with its ability to survive in them being a key factor in its abundance across the UK (and indeed right across Europe). Habitats include woodland, hedgerows, gardens, parks, heathland, moorland, r
