Brief report on "Age attained by the Hyacinth Macaw" published in the Auk in 1920 (Vol. XXXVII, Page 293)

A venerable specimen of the Hyacinth Macaw (Anodorhynchus hyacinthus (sic) well known to the visitors to the Philadelphia Zoological gardens, died on February 28, 1920. The records of the Zoological Society show that the bird was received on July 22, 1893 so that it had been on exhibition for over twenty-six years. How long the bird had lived before it was captured it is of course impossible to say. At the time of its death it was still in perfect plumage - Witmer Stone, Academy of Natural Sciences, Philadelphia, Pa.
