Often, they will stop eating everything except millet and seed when placed in a new home. It takes much more time for them to become comfortable in their new surroundings. However, once settled in, they are just as intelligent and comical as their more assertive cousins and will swing, attack and play with their toys for hours. Mexican parrotlets are the only parrotlets not found in Central or South America. One of the larger species, Mexicans are much less active than other parrotlets.
Males have bright turquoise rumps and wings.
Females have light green faces with no yellow. These parrotlets can be very difficult to breed often only producing one clutch every year or two. Most parrotlets are capable of producing multiple clutches but even when the clutch is lost Mexicans do not lay again that season. In addition to being less active, they are also much more docile than their South American counter-parts. Unusually sensitive, they stop eating when stressed subjecting them to a compromised immune system often resulting in bacterial infections.
