the rose-ringed parakeet, can also talk, but some may never learn if not trained at an early age. The Derbyan parakeet (Psittacula derbianais) is an excellent talker. The clarity of their speech has been compared to that of amazon parrots although they may not learn extensive vocabularies. The slaty-headed parakeet (Psittacula himalayana) generally does not learn to talk. Songbirds Hill mynahs Hill mynahs (tropical members of the starling family of birds) are renowned for their ability to mimic the human voice. It has been claimed that the hill mynah is the best talking bird and the best mimic in the world. Canary A Domestic or Atlantic canary (Serinus canaria forma domestica) named Pinchi, who lived in 1966 from 2–3 months of age with a resident of the city of Leningrad (USSR), learned to imitate the human speech of his owner-educator and weave it into his song. The bird began to repeat the tunes of its mistress's high voice "Pinchi, Briks – cute birds, weird little birds, these are these birds" after 4 months and in year and a half canary Pinchi completely formed his song from the words of human speech and the trills of birds. The singing of canary Pinchi, containing the words of human speech, was recorded on a tape recorder, and then published on a gramophone record in the record company Melodiya. In 1976, copies of this record were attached to the book by A. S. Malchevsky and co-authors "Birds in front of a microphone and a camera", and were also sold separately. Corvids Several members of the corvids or crow family, such as ravens, can mimic human speech. The best talking crows may be the ones found in captivity at zoos and wildlife centers. Starlings European starlings (Sturnus vulgaris) are exceptional mimics, including human speech. Their ability at mimicry is so great that strangers have looked in vain for the human they think they have just heard speak. Mockingbirds The northern mockingbird (Mimus polyglottos), as both the common and taxonomic names suggest, are mimickers of a great number of sounds. This includes human speech. Lyrebirds In Australia, lyrebirds are great mimics of many sounds, including the human voice. Lyrebirds have three syringeal muscles whereas most other songbirds have four. This could make the syrinx of the lyrebird more flexible. In a study comparing the sonograms of lyrebirds and Australian magpies during mimicking, the author stated that
