The Birds can only learn whistles and hoots. They learn them by attempting to mock voice pitch.
Observational learning
Learn songs
Yes, most can. Getting to learn birds songs make it easier to tell what kind of bird it is. (Example... Some birds have long loud songs and others, short soft songs... some even the other way around.)
Young birds learn their songs through a process called vocal learning, which involves listening to adult males of their species. They typically have a sensitive period during which they must hear these songs to accurately mimic and integrate them into their own vocalizations. This combination of innate ability and learned behavior ensures that songs are passed down through generations, allowing birds to communicate effectively within their species. The exposure to adult songs is crucial for developing their unique vocal patterns.
Wild birds of the same species learn their songs primarily through a combination of innate behavior and social learning. Young birds listen to adult males singing and memorize the sounds during a critical learning period, often referred to as the "sensitive phase." They then practice and refine their songs through vocal imitation, gradually developing the species-specific song. Environmental factors and interactions with other birds also play a role in shaping their song, ensuring that it remains consistent within the species.
Finches learn their songs primarily from adult male finches, especially their fathers, during a critical period in their early development. This learning process involves listening to and mimicking the songs of these adult birds, which helps them develop their own unique song. The process typically includes a sensory phase, where young finches memorize the songs, followed by a sensorimotor phase, where they practice and refine their singing. Environmental factors and social interactions also play a role in shaping their vocalizations.

Inheritance influences the development of birdsongs as the basic song for all birds of the same species is the same. If a bird is raised in isolation it can still sing but its song will lack complexity. Learning also plays a role as young birds learn details of songs from their fathers or other birds. This ability to learn is genetic.
Birds do not sing for pleasure, they sing to communicate with other birds. There are territorial songs intended to warn off competitors, and mating songs intended to attract mates.
All birds can learn to varying degrees. Some can talk, some whistle or mimic other sounds. Some only sing their normal song. Birds learn their songs from their parents and others in their flock. A captive bird will imitate you or other sounds they hear repeatedly.
Although a noted songster, possessing a sweet song, even during the night, the nightingale does not imitate other birds songs. The mockingbird does, however, and even cell phone rings and other human made sounds. The mockingbird can imitate up to 80 other birds songs, and this appears to be an instinctive behavior.
