Troglodytes[a] is a genus of small passerine birds in the wren family. These wrens are around 9–14 centimetres (3.5–5.5 in) long. They are brownish above and somewhat paler below, with strong legs. Their short rounded wings and frequently cocked tail have a dark barred pattern. The flight is direct and buzzing.
Troglodytes wrens are generally found in somewhat cooler habitats than most of their relatives.[1] Most of the species are found in the mountains from Mexico to northern South America. Several species are found in temperate latitudes. The former house wren occurs widely in both tropical and temperate lowlands, but is now split into several species, one each in North and South America, and the others island endemics. In some older texts, the hardy Troglodytes troglodytes (then named northern wren) was treated as having a wide distribution in Europe, Asia, North Africa, and North America, but it was subsequently split into three species, of which the Eurasian wren is the only wren of any genus found outside the New World.[2][1] The Cobb's wren of the Falkland Islands is another species which tolerates harsh conditions well.
Like other wrens, they are elusive as they hunt for small insects and spiders, but they readily reveal their positions through their loud songs.
They are territorial birds, but the tiny Eurasian and winter wrens will roost communally in a cavity in cold weather to help conserve heat.
Systematics and species
[edit]The genus Troglodytes was described by the French ornithologist Louis Pierre Vieillot in 1809.[3] The type species was subsequently designated as the Troglodytes aedon, the northern house wren.[4]
The closest living relatives of this genus are the timberline wren Thryorchilus browni, and the marsh and grass wrens in the genus Cistothorus.[1][5]
The Eurasian, Pacific, and winter wrens are less closely related to the other members of the genus, and are split as the separate genus Nannus by some authors. These three are basal to a clade that includes Cistothorus, Ferminia, and Thryorchilus, as well as the rest of Troglodytes.[1]
Within the remaining core of the genus, there appear to be two clades, one comprising the house wren group and another containing Central and South American species.[5] The relationships of the rufous-browed and brown-throated wrens are indeterminable with the present molecular data; they appear fairly basal and the former might be closer to the house wren group than the latter.[5] The Santa Marta wren is quite enigmatic and little-studied.
A number of the Troglodytes species, such as the Clarion wren, were formerly considered subspecies of the house wren, and the Central and South American forms of the house wren have also now been further split as the southern house wren T. musculus, as have the Caribbean island endemic wrens Cozumel wren T. beani, Kalinago wren T. martinicensis, St. Lucia wren T. mesoleucus, St. Vincent wren T. musicus, and Grenada wren T. grenadensis.[6] The Socorro wren, in older texts placed in Thryomanes (Bewick's wren), proved to be a close relative of the house wren complex, as indicated by "manners, song, plumage, etc.",[7] and by biogeography and mtDNA NADH dehydrogenase subunit 2 sequence analysis.[5]

Notes
[edit]- ↑ Etymology: Ancient Greek τρωγλοδύτες "cave-dwellers" (compare troglodyte), from trogle (τρώγλη) "hole" + dyein (δυειν) "to enter", in reference to the tendency of these wrens to enter small crevices as they search for food.
