Songbirds and parrots are the two groups of birds able to learn and mimic human speech. [5] [7] Both belong to the clade Psittacopasseres. If then introduced to wild birds, the wild birds may also mimic the new sounds. This phenomenon has been observed in public parks in Sydney, Australia, where wild parrots utter phrases such as "Hello darling ...
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.

Bird vocalization includes both bird calls and bird songs. In non-technical use, bird songs are the bird sounds that are melodious to the human ear. In ornithology and birding , songs (relatively complex vocalizations) are distinguished by function from calls (relatively simple vocalizations).
Mimicry is an evolved resemblance between an organism and another object, often an organism of another species. Mimicry may evolve between different species, or between individuals of the same species. Often, mimicry functions to protect from predators. [11] Mimicry systems have three basic roles: a mimic, a model, and a dupe.
The syrinx enables some species of birds (such as parrots, crows, and mynas) to mimic human speech. Unlike the larynx in mammals, the syrinx is located where the trachea forks into the lungs. Thus, lateralization is possible, with muscles on the left and right branch modulating vibrations independently so that some songbirds can produce more ...
The folds mimic the natural creases found in leaves, channeling more light into the cell. The researchers claimed in 2015 that the leaf-like cells generated 47 percent more electricity than those ...
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. [7]
Steller's jay is also a noted mimic: it can imitate the vocalizations of many species of birds, other animals, and sounds of non-animal origin. It often will imitate the calls from birds of prey such as the red-tailed hawk , red-shouldered hawk , and osprey as a warning of danger to others or territorial behavior, causing other birds to seek ...
