Hot take: Amazon parrot are actually easier than people think
I see SO many posts about how parrotlet are difficult birds. Honestly? After owning one for 18 months, I think they're one of the more manageable parrots IF you put in the time upfront. The key is consistency. Am I completely wrong? Fight me.
So I had this exact problem about a year ago. Let me share what I learned. The key thing is putting the food bowl higher up β birds feel safer eating at height. A lot of people also recommend adding more variety in perch textures and sizes. My avian vet in the Danforth also suggested checking for stress from loud noises like construction which can sometimes be an underlying factor. Good luck β feel free to DM me if you have questions!
I've done a ton of research on this because my African Grey had the same issue. Here's what I learned: the most common cause is not enough quality sleep β they need 10-12 hours uninterrupted. What worked for us was covering the cage partially at night for 12 hours of uninterrupted sleep. I also started rotating toys weekly so they always have something "new" and noticed improvement within a week. It's a process but it gets better.
This is one of those topics where I think there genuinely is no right answer. Both sides have valid points.
