A scanned copy of the plate of the Glaucous Macaw in Wagler's Monographia Psittacorum, published in 1832, by Dr. Julianne Diller

The latest reports on the Sissen's trial can be found on the dedicated website page. I have also been sent a scanned copy of the plate of the Glaucous Macaw in Wagler's Monographia Psittacorum, published in 1832, by Dr. Julianne Diller, Librarian at the Zoologische Staatssammlung in Munich. As this is the first illustration of this now extinct blue macaw, I am very grateful to her.
