Anodorhynchus

 
        The Anodorhynchus genus consists of three large blue macaws. All of them including extinct and extant species have a blue or indigo body with yellow skin patches around the eyes and mouth.  The Hyacinth macaw is the largest parrot species but the Kakapo is the heaviest species weighing up to 9 pounds. the Hyacinth Macaw is about 3 to 4 pounds. Hyacinth macaws can have about 1000 psi (Pounds per square inch) and some say that they can have 2000 psi! According to IUCN red list the Hyacinth Macaws are vulnerable in the wild and their population is decreasing due to pet trade. They can be kept as pets legally you can find them here. Lear's Macaws are distinguishable by the patches of skin by the mouth. The patch is rounder and is shaped more like a waterdrop and is lighter and greener in color. The Hyacinth Macaw has a longer skin patch that runs along the whole lower beak and they are a deep blue, almost indigo-colored. The Lear's Macaw is endangered and it is unknown whether the population is increasing or decreasing.  They cannot be kept as pets. The Glaucous Macaw is most likely extinct and the last sighting was in the 1960s but no one knows for sure whether it is extinct so it is considered critically endangered.
