The Yellow Sided Green Cheeked Conure (Mutation) is a smaller bird; approximate lengths are 9 - 10 inches. It is a very quiet bird like all the Pyrrhuras. There is little difference between the two except the coloring. The Green cheek has somewhat greener cheeks and the upper side of  their tail  is maroon colored.They are fast becoming a bird keepers favorite, because of their sweet personalities. They are the perfect pet for people living in apartments,  they are small, not very messy, they will learn to talk a little and are very lovable. They love to take baths and can be trained to shower with their companions. They are excellent pets for elementary school aged children, as they are so friendly and children this age are not intimidated by the size of the bird.
	The Green Cheek is a playful bird, and is very trainable. Some people say that the Green Cheek can get 'nippy' in it's older age, but many others dispute that. The Green Cheek can be loud, but nowhere near as loud as their Aritanga counterparts. They are not dimorphic and sex can be only ascertained by DNA or surgical methods.
