Poor bird, look's like a scarlet. I don't think that's Maggie, Pretty sure Maggie was a Green Wing, and she had a lot more coloring in/around her cheeks IIRC.
Nope, that's a Scarlet, and Maggie was a Greenwing. They are commonly mistaken for the same macaw but once you know what the differences are, the easier it becomes to differentiate between the two.
Greenwings are much larger than Scarlets. They have no yellow and instead have a band of turquoise green/blue. They also have red feathers on the lines on their face, whereas the scarlet has only white. A Greenwing will never molt and turn yellow, there may be a hint of yellow where the red/green/blue meet but otherwise all green. Scarlets have a lot less green, only a small band of it usually.
