Alex ditemukan oleh seorang ilmuwan bernama Irene Pepperberg tahun 1977

None were as sharp as Alex Even though Professor Pepperberg eventually began teaching other parrots in her lab none of them seemed to match Alex in intellect or language acquisition

Kemampuannya tidak hanya menirukan ucapan orang lain, Alex mampu menghitung dan membedakan warna. Bahkan bisa bercakap-cakap
Remarkable lesson Over time Professor Pepperberg taught Alex to recognise colours and shapes to prove that he could understand her commands

Hubungan antara Alex dan Irene berlangsung lama, bahkan mereka saling menyayangi seperti pasangan

Tapi sayang, pada tahun 2007 Irene harus kehilangan burung beo afrika ini di usianya ke-30 tahun. Dan kalimat terakhir Alex adalah…
The parrot with the moving last words

“you be good. I love you.”
