Its powerful bill was uniquely adapted for cracking the hard nuts of certain palm species, a specialized feeding strategy characteristic of Anodorhynchus macaws. Whi...
The historical range of the Glaucous Macaw spanned a relatively narrow corridor in subtropical South America, encompassing parts of Brazil (specifically western Mato Grosso do Sul and possibly Rio Grande do Sul), Paraguay, northeastern Argentina (Corrientes Province and Santa Fe), and Uruguay.
