Description

The song in this clade is essentially territorial, because it communicates the identity and whereabouts of an individual to other birds, and also signals sexual intentions. Sexual selection among songbirds is highly based on mimetic vocalization. Female preference has shown in some populations to be based on the extent of a male's song repertoire. The larger a male's repertoire, the more females a male individual attracts. It is not to be confused with bird calls that are used for alarms and contact and are especially important in birds that feed or migrate in flocks. While almost all living birds give calls of some sort, well-developed songs are only given by a few lineages outside the songbirds. And still, not all songbirds proffer a call that is distinctly melodious. Songbirds do, however, possess a highly developed vocal organ, the

, that enables their sonorous activity. This organ, also known as a song box, can be found where the windpipe meets diverging bronchial tubes which lead to the lungs. The organ is a solid, bony structure lined with a film of membranes which air passes through as the songbird calls. While the song boxes of songbirds vary in size and intricacy, this does not necessarily determine the songbird's ability to voice their song. Researchers believe this has more to do with the length of the windpipe. Other birds (especially non-passeriforms) sometimes have

The birds from higher altitudes have evolved thicker downs (also known as jackets) to protect themselves from colder temperatures. Their feathers have outer and inner portions, with the lower down being fluffier and warmer to provide increased warmth.

Song repertoire and courtship

Sexual selection can be broken down into several different studies regarding different aspects of a bird's song. As a result, songs can vary even within a single species. Many believe that song repertoire and cognition have a direct relationship. However, a study published in 2013 has shown that cognitive abilities may not all be directly related to the song repertoire of a songbird. Specifically, spatial learning is said to have an inverse relationship with song repertoire. So for example, this would be an individual who does not migrate as far as others in the species but has a better song repertoire. This suggests an evolutionary trade-off between possible alleles. With natural selection choosing traits best fit for reproductive success, there could be a trade-off in either direction depending on which trait would produce a higher fitness at that time period. Song repertoire can be attributed to male songbirds as it is one of the main mechanisms of courtship. Song repertoires differ from male individual to male individual and species to species. Some species may typically have large repertoires while others may have significantly smaller ones.

Mate choice Mate choice is one of the primary mechanisms under which evolution can occur. It is characterized by a "selective response by animals to particular stimuli" which can be observed as behavior.Bateson, Paul Patrick Gordon. "Mate Choice." Mate Choi ...

in female songbirds is a significant realm of study as song abilities are continuously evolving. Males often sing to assert their dominance over other males in competition for a female, sometimes in lieu of a combative episode, and to arouse the female by announcing a readiness to mate. Though less frequent, females have also been known to sing occasionally a duet with a mate as an affirmation of their partnership. While some will sing their song from a familiar perch, other species common to grasslands will sing a familiar song each time they fly. Currently, there have been numerous studies involving songbird repertoires, unfortunately, there has not yet been a concrete evidence to confirm that every songbird species prefers larger repertoires. A conclusion can be made that it can vary between species on whether a larger repertoire is connected to better fitness. With this conclusion, it can be inferred that evolution via natural selection, or sexual selection, favors the ability to retain larger repertoires for these certain species as it leads to higher reproductive success. During times of courtship, it is said that male songbirds increase their repertoire by mimicking other species songs. The better the mimicking ability, retaining ability, and the quantity of other species mimicked has been proven to have a positive relationship with mating success. Female preferences cause the constant improvement of accuracy and presentation of the copied songs. Another theory known as the "song-sharing hypothesis" suggests that females prefer simpler, more homogenous songs that signal a male of familiar territory. As birdsong can be broken into regional dialects through this process of mimicry, the foreign song of a newcomer suggests the lack of territorial possession. This can be costly in the wake of territorial conflicts between disparate songbird populations and may compel a female to prefer a male spouting a familiar song of the area.

to the Passerida. The remaining 15 oscine families (343 species in 2015) form a series of basally branching sister groups to the Corvoid - Passerid clade. All of these groups, which form at least six successively branching basal clades, are found exclusively or predominantly in Australasia. Australian endemics are also prominent among basal lineages in both Corvoids and Passerids, suggesting that songbirds originated and diverged in Australia. Scrubbirds and lyrebirds, of which there are just two species of each, represent the oldest lineage of songbirds on Earth. The rufous scrubbird, ''Atrichornis rufescens'', is essentially confined to the Gondwana Rainforests of Australia World Heritage Area, occurring in both Queensland and New South Wales sections.
