[AS.] A small brown bird having active and lively habits. It has a domed nest needlessly large for the size of the bird, and near an occupied nest are generally one or more nests unfinished. It is extensively found in Europe, and inhabits Palestine. The winter wren and house wren are common in North America. In Britain there are the wood wren and willow wren ; also the chiff-chaff, which, from its nest, is sometimes called "oven" bird. Wrens, like robin redbreasts, whistle all the year round, times of hard frost excepted.
