Song learning in juvenile birds occurs in two stages: sensory learning, which involves the juvenile listening to the father or other conspecific bird and memorizing the spectral and temporal qualities of the song (song template), and sensorimotor learning, which involves the juvenile bird producing its own vocalizations and practicing its song ...
Different aspects and features of bird song such as structure, amplitude and frequency have evolved as a result of sexual selection. [5] Large song repertoires are preferred by females of many avian species. [6] One hypothesis for this is that song repertoire is positively correlated with the size of the brain's song control nucleus (HVC). A ...
Birds with eyes on the sides of their heads have a wide visual field, while birds with eyes on the front of their heads, such as owls, have binocular vision and can estimate the depth of field. [ 122 ] [ 123 ] The avian ear lacks external pinnae but is covered by feathers, although in some birds, such as the Asio , Bubo and Otus owls , these ...
Vocal learning is the ability to modify acoustic and syntactic sounds, acquire new sounds via imitation, and produce vocalizations. "Vocalizations" in this case refers only to sounds generated by the vocal organ (mammalian larynx or avian syrinx) as opposed to by the lips, teeth, and tongue, which require substantially less motor control.

There are two essentially different kinds of ornithology: systematic or scientific, and popular. The former deals with the structure and classification of birds, their synonymies, and technical descriptions. The latter treats of their habits, songs, nesting, and other facts pertaining to their life histories.
Our network analyzed over 500 photographs of bird species provided by the Macaulay Library at the Cornell Lab of Ornithology, whose extensive media collection helps researchers identify and study ...
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. [8]
Euphonias are members of the genus Euphonia, a group of Neotropical birds in the finch family. They and the chlorophonias comprise the subfamily Euphoniinae.. The genus name is of Greek origin and refers to the birds' pleasing song, meaning "sweet-voiced" (εὖ eu means "well" or "good" and φωνή phōnē means "sound", hence "of good sound").
