What collections you are responsible for?
I oversee all of the Vertebrates specimens (animals with backbones) in the Museum including the offsite Collections of primarily birds and mammals. Occasionally I will create temporary exhibits, some of which have traveled such as “Cracids: on Wings of Peril.” I also provide tours, training, and content for Exhibits relating to Vertebrate Zoology. For example, the Frensley/Graham Hall of African Wildlife was completely re-done ground up 2001–04. The year 2014 was very busy with the opening of Glassell Hall, Vintage Texas Wildlife Dioramas, and the Farish Hall of Texas Wildlife.
The Museum’s Vertebrate Zoology collection contains approximately 5000 specimens. Birds represent approximately 65% of the collection, and mammals approximately 30%, with herps and fish being represented to a lesser extent. The Texas coastal bend region is the major part of the collection, with other holdings including Africa, Latin America, Threatened and Endangered species, and select taxonomic groups (pigeons/doves and gamebirds). A constant effort is made to encourage and facilitate the use of the collections for research by students, scholars and interested scientists.
Why did you decide to work in a Museum?
My fascination with critters began at a very young age, when my father and I kept exotic gamebirds as a hobby. My mother was very good about keeping me cultured though, enrolling me in Nature classes at HMNS and other places when I was a kid, and later taking me to visit larger museums in the northeast when we were visiting family or vacationing. It was during one of these visits, that I recall being completely overwhelmed at the mount of a Dodo bird – how did they recreate something that was extinct? I was extremely fascinated with extinction, birds and Endangered species at the time (I was in my teens)… But I think my actual decision to work in a museum was influenced by the mentors who actually trained me. I was in awe of these personal heroes, and wanted to be like them; most of them still walk among us, others have passed on, but what they have collectively provided me with is hardly forgotten. They include: Dean Amadon, Keith Arnold, Richard Bodmer, John Eisenberg, Knox Jones, Nancy Crocker-Mulligan, Stuart Strahl, and Richard Strauss.
What is your favorite specimen, and why? Is it on exhibit?
The Okapi (Okapia johnstoni, HMNS VM 505) mount in the African Wildlife Hall is among my favorite of specimens in the museum for many reasons. First and foremost, they are rather rare in terms of animals on display. However, everything the Okapi represents, from exploration to history to conservation of rare species, is a fascinating story in itself.
At a time when most of Africa seemed more alien to explorers than distant planets are today, Dr. David Livingstone, a young Scot of humble means, marched into the heart of darkness, hoping to help Africa’s people. Livingstone’s writings lifted the shroud of mystery from Africa and invigorated the anti-slavery crusade. When Livingstone had not been heard from for several years, his absence had become a matter of international concern. It was then that the New York Herald dispatched their explorer-journalist Henry Stanley in 1869 to search for Livingstone. Stanley finally found Livingstone in November 1871 in a small southeast African town, and greeted Livingstone with the famous quote, which is still know today, “Dr. Livingstone, I presume”.
Part of Stanley’s journey took him through the deep, dark Congo Basin, where some historians believe he was the first explorer to witness the rare Okapi. Stanley was surprised by the Wambutti pygmies’ indifference to the animal, explaining they sometimes caught a similar animal in their traps.
Meanwhile, in England, rumors of the strange jungle beast reached the ears of Philip Lutley Sclater, Secretary of the Zoological Society of London at the time. In 1899, Sclater set out to search for the Okapi, as part of a Cecil Rhodes-British Government team led by Sir Harry H. Johnston. After talking to the local people, Sclater assumed the strange animal must be a forest-dwelling zebra. Johnston later provided Sclater with two pieces of Okapi skin bearing stripes, supporting the theory that the Okapi was a zebra, but he couldn’t explain the strange, two-toed tracks he found because zebras walk on just one toe. Sclater thought the tracks had been made by another animal, perhaps an antelope. The mystery was solved when an okapi skull was discovered – it was a type of forest giraffe.
Johnston was actually the first explorer to view a live Okapi, and it was named for him, Okapia johnstoni, although the animal was not viewed in a European Zoo until 1918. Nonetheless, the discovery of the Okapi in 1900 created such excitement to foreign scientists that the American Museum of Natural History sent Herbert Lang and James Chapin to explore the region from 1909 – 1915, with subsequent expeditions following.
