The wren, one of the smallest European birds (it weighs only 8 to 9 grams), makes its home in woods throughout most of Europe. It is also found in parts of Asia, northwest Africa and North America. This agile and restless bird remains in its breeding grounds throughout the year; only individuals from the north travel south for the winter.
Its favourite habitat is woods with thick undergrowth, though it also likes thickets alongside ponds, ditches and streams. It is sometimes found in parks and, in winter, frequently enters villages. It also enjoys digging around in piles of underbrush, where it can usually find something to eat. In spring the male stakes out his nesting territory which he stoutly defends and, at the end of April, he begins building several nests, which are made of plant stalks, small twigs and moss and provided with a tiny side entrance.
The female then examines the results of his efforts, selecting the one she considers best, and it is then lined with animal hairs and feathers. The nests are located in the branches of spruce trees, stacks of wood, between roots, in piles of brushwood and similar sites, and the ones not chosen by the female are used by the male as sleeping quarters. The hen incubates the 5 to 7 eggs alone for 14 to 16 days and 15 to 17 days after that the young leave the nest.
In June the parent birds often have a second brood, the male taking the first brood to roost in one of the rejected nests while the female is occupied with incubation. The wren’s diet consists of insects, insect larvae, spiders and small seeds.
