The pictures are blurry and no good but the article is actually pretty good at explaining why birds vocalize and why parrot imitate human sounds. But the piece de resistance is the video at the very end! It's of an amazon in a Spanish speaking household and he doesn't only cry EXACTLY like a baby but he does all different kinds of crying - just like a baby would do!

PS The lady owner speaking to the parrot in Spanish is saying just different versions of things like "Why does the baby cry?" "Don't cry, baby" in a baby-talk sing-song kind of voice like one would use with a crying baby one is trying to comfort but which, apparently, cues the bird into crying
