Penguin is not native to India, so there is no exclusive Telugu name for it. It is appropriate to call it a penguin (à°ªà±†à°‚à°—à±à°µà°¿à°¨à±) only. But as per Brown dictionary it can be called as samudrapu kaaki (à°¸à°®à±à°¦à±à°°à°ªà± à°•à°¾à°•à°¿).
People often use the English word tomato (టొమాటో) as such in Telugu even though it is called Ramamulagakaya (రామములగకాయ) in Telugu. Some Telugu people also call it as Takkali (తక్కాళి) which is in fact a Tamil word.
Doves and sometimes pigeons make a sound close to that description. Owls make a sound similar, but their call is more of a 'hoo' sound or 'hoot.' If the bird makes a 'cuckoo' sound then it is a cuckoo bird.
