Animal specimen - Common Buzzard, Trustees of the Australian Museum, 1860-1880

With finely tuned hearing, they are able to detect ...The Common Buzzard is part of the buteo genus (Latin for buzzard or hawk) which indicates it is part of the raptor group whose features include a medium to large build, a strong body and larger wings. The family includes birds of prey such as hawks and buzzards. Like their name suggests, Common Buzzards are very ‘common’ in the UK but can also be found in other parts of Europe, Africa and Asia. The birds’ habitat consists of woodland, shrubland, forest, wetlands and countryside, and they can live in cold, tropical and temperate climate zones. Similar to other raptor species, Common Buzzards make their nests in tree branches or tree forks. With finely tuned hearing, they are able to detect small marsupials, and their diet consists of small amphibians, birds and mammals. Normally solitary, these raptors can occasionally be seen with others. Common Buzzards are classified as of ‘Least Concern’ on the IUCN Red List. While there is some noticeable fading of this particular taxidermy specimen’s plumage, it is relatively well presented. The completely black eyes and string through the nose of the specimen seem to be taxidermy/curatorial choices, as this is not something that is normally found on living versions today, and the eyes of Common Buzzards are normally golden eyes with black pupils. It is interesting to note, when considering the selected artificial eyes, that the original swing tag labeled this specimen as Saleo tinnunculus Lina, a form of kestrel (known to have complete black eyes), which perhaps explains this taxidermist choice. As a Common Buzzard, this particular specimen could have had its frame and breast area bulked out a little more, as birds within the buteo genus are generally recognised to be of medium to large build. Overall however, this is a fairly reasonable and accurate representation of the species. This specimen is part of a collection of almost 200 animal specimens that were originally acquired as skins from various institutions across Australia, including the Australian Museum in Sydney and the National Museum of Victoria (known as Museums Victoria since 1983), as well as individuals such as amateur anthropologist Reynell Eveleigh Johns between 1860-1880. These skins were then mounted by members of the Burke Museum Committee and put-on display in the formal space of the Museum’s original exhibition hall where they continue to be on display. This display of taxidermy mounts initially served to instruct visitors to the Burke Museum of the natural world around them, today it serves as an insight into the collecting habits of the 19th century.This specimen is part of a significant and rare taxidermy mount collection in the Burke Museum. This collection is scientifically and culturally important for reminding us of how science continues to shape our understanding of the modern world. They demonstrate a capacity to hold evidence of how Australia’s fauna history existed in the past and are potentially important for future environmental research. This collection continues to be on display in the Museum and has become a key part to interpreting the collecting habits of the 19th century.With similar colourings and features to a range of raptor species, the Common Buzzard can often be mistaken for other varieties of buteo and raptor. The bird’s plumage generally varies by location, but normally includes a variety of shades of brown, commonly with darker brown on its back and lighter coloured feathers on its breast, underbelly areas and face. These birds normally have fine bands on their tail and darker tipped wings. Common Buzzards have smaller heads with a band of yellow around the base of their small curved beaks and golden yellow eyes. This particular specimen’s feathers have faded and he stands upon a wooden perch with an identifying tag hanging from its right leg.Swing Tag: Swing tag obverse seems to read: ‘…io [?
