Hi, I’m Malik Miller. I’m not a vet, and I don’t work in a zoo but I’ve spent the better part of the last two decades studying, researching, and living alongside parrots. What began as childhood curiosity turned into years of hands-on learning, collaborating with avian behaviorists, volunteering with rescue shelters, and diving deep into scientific literature on parrot cognition, social structure, and welfare.

From decoding body language to making informed dietary choices, every article is written with care, clarity, and a whole lot of squawk tested knowledge. Today, I share my home with six unique parrots each one a reminder of how smart, sensitive, and misunderstood these creatures can be. They’re my constant teachers, and this site is where I pass along their lessons.
