Nest cavities are usually a few meters above ground at most, [21] [22] but occasionally on cliffs as high up as 15 m (49 ft) and more at least in southern populations [verification needed]; they may be natural or man-made, often using bird houses. Northern house wrens are feisty and pugnacious animals considering their tiny size.
As these wrens are year-round residents, they are at a higher risk than other species to acquire mercury in their blood. Nest abandonment and failure to raise young are more common with higher mercury content. [38] Exposure, and prolonged periods of cold, ice, and snow is thought to affect the wren nestling and adult populations, respectively. [17]
The Wren's Nest National Nature Reserve is world-famous geologically for its well-preserved Silurian coral reef fossils.Considered the most diverse and abundant fossil site in the British Isles, [9] more than 700 types of fossil have been found at the site, 86 of which are unique to the location, [10] including Calymene blumenbachii, a trilobite nicknamed the Dudley Bug or Dudley Locust by ...
The nest is an oval structure attached to marsh vegetation, entered from the side. The male builds many unused nests in his territory. A hypothesis of the possible reason to why males build multiple "dummy" nests in their territory is that they are courting areas and that the females construct the "breeding nest" in which she lays her eggs.

The Pacific wren nests mostly in coniferous forests, especially those of spruce and fir, where it is often identified by its long and exuberant song.Although it is an insectivore, it can remain in moderately cold and even snowy climates by foraging for insects on substrates such as bark and fallen logs.
The winter wren nests mostly in coniferous forests, especially those of spruce and fir, where it is often identified by its long and exuberant song. Although it is an insectivore , it can remain in moderately cold and even snowy climates by foraging for insects on substrates such as bark and fallen logs.
The name "Wren's Nest" came from his discovery of a family of wrens living in the mailbox in the spring of 1895. [5] After several years of correspondence, Indiana poet James Whitcomb Riley visited Harris at Wren's Nest in 1900. Harris's children were especially interested in Riley and nicknamed him Uncle Jeems. [6]
In Anglophone regions, the Eurasian wren is commonly known simply as the "wren", as it is the originator of the name. The name wren has been applied to other, unrelated birds, particularly the New Zealand wrens (Acanthisittidae) and the Australian wrens . Most wrens are visually inconspicuous though they have loud and often complex songs.
