The National Audubon Society’s Guide to North American Birds is another free online resource, where more than 800 North American bird species are catalogued with songs, photos, and info about ...
The songs of different species of birds vary and are generally typical of the species. Species vary greatly in the complexity of their songs and in the number of distinct kinds of song they sing (up to 3000 in the brown thrasher); individuals within some species vary in the same way.
Several species of birds can mimic the songs of other birds, or even mechanical sounds. These include, with varying degrees of success, starlings, mockingbirds, thrashers, crows and ravens, parrots, myna birds, blue jays, [21] lyrebirds, Lawrence's thrushes, Acrocephalus, marsh warblers, and others.

In many species, young birds learn songs from adult males of the same species, typically fathers. [30] This was first demonstrated in chaffinches (Fringilla coelabs). Chaffinches raised in social isolation develop abnormal songs, however playing recordings of chaffinch songs allows the young birds to learn their species-specific songs. [31]
How do birds get their colors? Understanding bird coloration combines biology and physics. There are two primary ways that birds get their color: pigmentation and the physical structure of the ...
The song of the lyrebird is a mixture of elements of its own song and mimicry of other species. Lyrebirds render with great fidelity the individual songs of other birds [14] [15] [16] and the chatter of flocks of birds, [17] [18] and also mimic other animals such as possums, [17] koalas and dingoes.

In males, however, most song system neurons respond maximally to the sound of the bird's own song, even more than they do to the tutor's song or any other conspecific song. [6] [7] In HVC, neurons switch from responding best to tutor song (35–69 days post-hatch) to responding best to the bird's own song (>70 days post-hatch). [8]
Musicologists such as Matthew Head and Suzannah Clark believe that birdsong has had a large though admittedly unquantifiable influence on the development of music. [2] [3] Birdsong has influenced composers in several ways: they can be inspired by birdsong; [4] they can intentionally imitate bird song in a composition; [4] they can incorporate recordings of birds into their works; [5] or they ...
