Size and the actual song quality don’t have a significant effect on the rate of finding partners for males. All they have to do is trill consistently for a long time and females are more likely tobe attracted. This just basically shows that the male House Wrens are much better at finding partners than humans are (at least in comparison to me). Older males tended to sing with higher trill consistency, which in turn, attracted more females to its domain, which she also notes is consistent with other studies. Cramer (2013) says that her findings showed no correlation between the quality of males and the quality of song, specifically the trills. Interestingly enough, House Wrens are known to practice polygyny, in which a male can have several female partners in a given time period.

The figure above shows two sonogram examples of male, House Wren songs, both recorded in Ohio. Kaluthota and Rendall (2013) also found that only one type of song was shared by all fifteen males, only fourteen songs were shared by more than ten males, and the rest were unique to the individual. A close phonetic of the male House Wren is tsi-tsi-tsi-tsi-oodle-oodle-oodle (Bent 1948). However, if you only count the songs that are most used by each male, then the effective repertoire of the average male House Wren is about 25 songs (Kaluthota and Rendall, 2013). The largest recorded repertoire of a house wren is 194 songs, although there is likely no sort of ceiling or limit on the size of its repertoire. Their song is described as rapid trills of frequency-modulated notes with an average of ten syllables per bout and around four different types of syllables. House Wrens sing with high intensity in periodic bouts prior to pairing and often did the same later in the breeding cycle to attract more partners. The beauty of the house wren is exactly this image: its striking simplicity and lack of presence mixed with quite an intriguing set behaviors found only through careful observation. Once in a while, a child might find a nest in an old shoe box in his garage after his mom nagged at him to do his chores. Anyone can go out on a still, summer day and notice the tiny bodies of feathers zoom past in the underlying shrubs and tree branches. The House Wren is a tiny, brown songbird that is commonly found in the backyards of homes across the western hemisphere.
