Description of Glaucous Macaw

in Monographia Psittacorum by Johann Georg WAGLER published in Munich in 1832 (Page 676).

Wagler managed to keep the various descriptions on the blue macaws separate in this slim volume, which was highly regarded in the early part of the 19th century. I should like to thank Dr. Juliane Diller, Librarian at the Zoologische Staatssammlung in Munich for sending me a scanned copy of the plate below.
