The northern house wren (Troglodytes aedon) is a very small passerine in the wren family Troglodytidae. It is found in southern Canada, the USA and Mexico. It occurs in most suburban areas in its range. It formerly included many subspecies resident in South America and in the Caribbean that are now considered as separate species. The name troglodytes means "hole dweller", and is a reference to the bird's tendency to disappear into crevices when hunting insects or to seek shelter.
The northern house wren was formally described in 1809 by the French ornithologist Louis Pierre Vieillot under the current binomial name Troglodytes aedon. The specific epithet is from the Ancient Greek aēdōn meaning "nightingale". The type locality was designated as New York City by Harry Oberholser in 1934. An earlier specific name, domestica in the combination Sylvia domestica, was introduced in 1808 by the American ornithologist Alexander Wilson. This was rarely used and in 1998 to conserve the widely used name aedon, the International Commission on Zoological Nomenclature suppressed the specific name domestica for the purposes of the principle of priority.

Possible
About 20% of wildlife watchers report a House Wren sighting in San Diego on a given day, based on 7,465 verified sightings from GBIF citizen-science data. It is the 50th most-seen of the 386 birds we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
April–May and September–October
In those months about 30% of wildlife watchers report a House Wren in San Diego on a given day, against about 10% in July–August and December–February, the lowest months. Those are among San Diego's driest months, with about 10 mm of rain a month against 55 mm in February.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most House Wren sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
9th of 38
Of the 38 cities where we can rate House Wren sightings, San Diego ranks 9th at about 20%. The best odds are in Sacramento (United States, about 30%), Los Angeles (United States, about 20%) and Philadelphia (United States, about 20%).
GBIF citizen-science records
It is estimated from how often the House Wren is recorded against all the birds logged in San Diego (7,465 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
