The global population of the blue-and-yellow macaw isn't endangered, but its numbers are decreasing because of habitat loss and hunting practices. Wild blue-and-yellow macaws are heavily hunted for the pet trade. The decrease in numbers hasn't been rapid, even though the population trend is negative.
The natural habitat of blue-and-yellow macaws is South America. The species is found in the rain forests of Venezuela, Brazil, Peru, Bolivia and Paraguay. BirdLife International lists the species as Least Concern, meaning there are still large numbers of them present in the mainland of South America.
The Paraguay population is considered endangered. The native Trinidad population has been extinct since 1970, but the species was re-established between 1999 and 2003 by introducing wild blue-and-yellow macaws from Guyana.
Their diet constitutes seeds, nuts and fruits. They ingest clay at riverbeds to filter out toxins from unripe nuts. Blue-and-yellow macaws mate for life. They usually live in pairs, but wild populations also congregate in flocks counting up to 25 birds.
Blue-and-yellow macaws are popular as pets. Their vivid appearance and the ability to talk contribute to their popularity. They are social and bond very closely to the owner. They tend to be loud and engage in destructive chewing, which is a part of their natural behavior. Accommodation is often an issue because of their large size.
