This series consists of glass plate negatives and other photographic materials with their original boxes relating to the Feather Book, ornithology, falconry, McGill University Library, and Casey Wood. The majority of the glass plates were produced in Berlin, Germany by Agra, while a few were produced in London, England and Toronto, Canada; which is indicated on the boxes the plates were contained in. On many of these boxes, McGill University librarian Dr. G. R. Lomer’s name appears, indicating these plates and photographic materials were used for library-related activities. Most of the plates, photographs, and photographic negatives (1927, 1930, 1956) show pages from the Feather Book by Dionisio Minaggio. Other glass plate negatives and photographic material depict artwork or images relating to ornithology and falconry, a portrait of Casey Wood (1927), Gronvold’s painting of Wood’s parrot John III (1930?), an ornithological archeological exhibit in the Redpath Library (1924), and library stacks in the Redpath Library (1924).

This series consists of falconry equipment, falconry exhibit labels and cards, a taxidermy young peregrine falcon, and two large burlap envelopes collected by Casey A. Wood from 1920-1937. Also included in this series are two Wolf Envelope Co. (Ohio) allsteel transfer cases manufactured by General Fireproofing Co., Ohio for book binding, found within Wood’s materials (191-?).
The leather falconry equipment and those worn by the young peregrine falcon were made by Otto Kals in Dusseldor-Benrath, Germany approximately in 1930-1937 and the falcon bells were made by Captain Russell Luff Meredith in the United States in 1920. The taxidermy young peregrine falcon in training is mounted on a weathering block and wears a United States Bureau of Biological Survey identification band, indicating that it was acquired legally. The falcon is also wearing a hood, a leash, a swivel, and a jess. A falcon bell is also held with the falcon as well as another leather jess, which is damaged.
Many of the artefacts in this series were purchased by Casey A. Wood due to his interest in falconry during his research with Marjorie Fyfe for the publication “The Art of Falconry,” a translation of Frederick II of Hosenstaufen's “de Arte Vendandi cum Avibus.” The falconry items were gifted to the Redpath Library at McGill University in autumn 1938 by Dr. Casey A. Wood.
The two large burlap envelopes previously held the contents of flat box MSG 1203-2-25, which contains photostats produced by the British Museum of Emperor Frederick II's manuscript “de Arte Venandi cum Avibus,” books I-II. It is evident on one envelope that labels were removed, while the other includes two original labels indicating Persian miniatures and drawings from the "fourteenth to nineteenth century, collected in North India, Bombay, Cairo, and London by Casey A. Wood," were previously contained. These two labels were scratched out and the note "Fred. II" was added.

This series consists of 23 volumes and 6 files focusing on travel, research, and expedition activities conducted during Casey Wood's ornithological research trips from 1920-1937, including periodical and newspaper publications written by Wood during this time. This series consists of manuscripts and articles relating to letters to friends and family providing accounts of his travels, clippings, photographs, printed ephemera, photostats, artwork, and feathers from John III. Some of the volumes contain manuscripts, notes, and/or photostats, while others are scrapbooks containing multiple record types seemingly curated, arranged and mounted by Wood or as directed by him.

Sanderson, Sir George Perley, Sir Charles Major, H. Kirke Swann, Edith Hayes, Emma Shearer Wood, W. E. Wait, Sun Engraving Co., Taylor and Francis, Bitty and Seaborne Ltd., Stuart Baker, G. M.

Some topics and research areas of note include ornithology, zoology, bird protection, travelling, nightingales (1920-1934), John III (1924, 1937), “Coloured Plates of the Birds of Ceylon” (1925-1927), Emma Shearer Wood and Blacker Library collections, Sinhalese weights, Wood’s heath, Ali ibn Isa, and political printed material on Italy during the late 1930s.
There are also a number of photostats of publications or manuscripts copied approximately in 1937 related to Emperor Frederick II’s “de Arte Venandi cum Avibus.” These photostats were used for reference during these research trips for Casey A.
