My Neleno on my profile picture is a Green Wing Macaw who is now 5 years old. Out of all the macaws Green wings are not know to be screamers or very loud. It's true that all Macaws can scream pretty loud but it is not normal for them to scream a lot, if so, there maybe a behavior issue or an ill Macaw.
Green wings are complete cuddle bugs but seem to be a one person Macaw. most Macaws are.
They love to eat and love spending time with the Family or where ever all the action is. They love to be in the middle of it.
Green Wings are very smart approx the same as a 4 year old child. They tend to figure out puzzels and learn tricks pretty fast and are easy trained using almonds or walnuts.
They love the shower. My Neleno has approx 75 to 100 words and most times will use them when performing an action, For example, If I cover him for the night, he always tells me good night or nite nite. When I feed him, he asks me if it's good.
Only when I give him treats will he say (Some) when my Guapo who has as many as 150 to 200 words talks and Neleno cannot keep up, he will tell Guapo to shut up Guapo Geeeeeeeze.
I take both my Green Wing Neleno and Male Eclectus Guapo everywhere i go that allows pets so they remain pretty busy and this also keeps them pretty social. Best of luck with you. If you have more questions, please feel free to ask. Thanks Joe
