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] Song learning generally involves a sensitive learning period in early life, during which young birds must be exposed to song from tutor animals in order to develop normal ...
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 ...
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.
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").
Songs generally consist of 1–5 syllables between 2 and 6 kHz. [5] Songs are usually spaced apart by 0.8–1 seconds although at times vireos may sing at a slower or faster rate. [5] Red-eyed vireos have a large repertoire size with one study finding an average of 31.4 song types per bird with one individual singing 73 different song types. [5]

Flamingos are gregarious wading birds, usually 3 to 5 feet (0.9 to 1.5 m) feet in height, found in both the Western and Eastern Hemispheres. Flamingos filter-feed on shellfish and algae. Their oddly shaped beaks are specially adapted to separate mud and silt from the food they consume and, uniquely, are used upside-down.
