The Great Auk (Pinguinus impennis), now displayed in sculpture on the southeast corner of the Enid A. Haupt Garden, was a flightless bird that fell prey to exploitation. A fast and facile swimmer and diver, the auk was characterized by its stubby wings, high-contrast black and white feathers, tall body, clumsy waddle, and large ribbed beak. It was initially found in dense colonies in the subarctic Atlantic, along the coasts of Canada, the United States, Iceland and Norway. But human predation caused its numbers to dwindle over the course of several centuries.
The sculpture is part of The Lost Bird Project, which seeks to create awareness about our fragile bird species. The creation of artist Todd McGrain, the project has been sponsored by the Smithsonian and other organizations. Four birds will remain in the Haupt Garden until spring 2015; a fifth bird is in the garden of the National Museum of Natural History, on the corner of 12th Street and Constitution Avenue.
Great auks spent most of their lives in the sea, seeking out land only during the spring breeding season. Their breeding sites were limited: the only suitable areas were those with reefs or rocky ledges, where the birds could waddle ashore to lay their eggs. Because the birds tended to concentrate in a few coastal areas, they were an easy target for hunters. Indeed, they were subjected to large-scale massacres, hunters killing them for their meat, oil, and feathers. The latter were used for clothes and pillows, the comforts of humans and profits of businesses taking precedence over the survival of the bird.
The last two Great auks were killed in 1844, although there were reports of a single bird remaining in 1852. The remains of the last two confirmed birds are preserved in formaldehyde in a museum in Denmark, a sad reminder of the bird’s demise.
The Great auk inspired Ogden Nash’s A Caution to Everybody:
Consider the auk;
Becoming extinct because he forgot how to fly, and could only walk.
Consider man, who may well become extinct
Because he forgot how to walk and learned how to fly before he thinked.

Interning at the Smithsonian Gardens this winter has been an enriching and rewarding experience. Getting the opportunity to work on so many different projects with so many different people in an intellectually-stimulating environment makes every day exciting and gratifying.
I was lucky enough to have the opportunity to assist in The Lost Bird Project’s arrival at the Smithsonian. Sculptor Todd McGrain began The Lost Bird Project to bring awareness to North American birds that have become extinct within the last two centuries. Todd has made five cast-bronze statues to immortalize five extinct birds: the Carolina Parakeet, the Passenger Pigeon, the Labrador Duck, the Heath Hen, and the Great Auk. He has traveled across the country installing his statues at locations where the birds were last seen. His statues have also been displayed at various institutions across the country.
Smithsonian Gardens is proud to host Todd’s statues in the Enid A. Haupt Garden located adjacent to the Smithsonian Castle. The Passenger Pigeon statue will be on display at the Urban Bird Habitat Garden located at the northwest corner of the National Museum of Natural History as a companion piece to the Smithsonian Institution Libraries’ exhibit Once There Were Billions: Vanished Birds of North America opening on June 24, 2014. The five sculptures will be on display through March 15, 2015.
The stories of these birds are tragic and highlights just how fragile nature can be. One-hundred years ago, massive flocks (numbering in the millions) of Passenger Pigeons flew across the Unites States. It was inconceivable at the time that the huge Passenger Pigeon population could become extinct. The birds became a stable food source across the country and as the demand for Passenger Pigeons grew, the birds were hunted to the point of extinction. Martha, the last Passenger Pigeon, died in captivity in 1914.
These two exhibits remind us of the importance of understanding how as humans we are intrinsically linked to our environment. Whether directly or indirectly, humans have a huge influence on our natural world and our every action affects many other organisms. These birds represent just a mere fraction of the species we have lost over the past two centuries. Pollution, excessive hunting and fishing, global warming, habitat loss are all anthropogenic factors that have contributed to the extinction of many species across the globe. By bringing awareness to this issue, we can work towards preventing such extinctions from happening in the future.

In the summer of 2013 a specimen lacebark pine (Pinus bungeana) at the National Museum of Natural History had been in decline for several months. An investigation by Greg Huse, Smithsonian Gardens arborist, found very large girdling roots growing just below the soil surface. In his report Lacebark Pine # 122 Evaluation at NMNH he determined there was little to no chance that the tree could be rehabilitated. Within two months of issuing the report the tree turned completely brown and it was clear that it need to be removed.
Or did it? Could the once stately pine on the corner of Madison Drive and 9th Street that formed the border between the Butterfly Habitat Garden and the newly established Urban Bird Habitat find a second life?
As a mature specimen of this slow growing pine the tree exhibited extraordinary exfoliating bark in a patchwork of white, olive, light purple and silver. The multi-stemmed trunk was a striking structural element in the landscape that would be a significant loss. Luckily, there was a way to save this feature and in doing so support wildlife enhancing the value and educational lesson of the space. The tree was the perfect candidate to become a snag.
By turning the soon to be rotting trunk and branches into a snag it gains a new purpose in the Urban Bird Habitat serving as a space for nests, nurseries, storage, foraging, roosting and perching for birds, small mammals, and other wildlife in the city.
Here is how we did it:
The garden is a dynamic landscape and one must be prepared to deal with the changes that nature brings. Through creative thinking the Smithsonian Gardens’ staff discovered a great opportunity to turn what could have been a significant loss to gardens into a valuable resource. Today many museum visitors stop to look at this unique tree along the National Mall. Most seems puzzled by its presence but their questions are answered by the Snag interpretive panel.
So what do you think? Does your garden have a spot for a snag? Please share your thoughts in the comments below.

Living with Wildlife: Snags – The Wildlife Tree from the Washington Department of Fish and Wildlife.
Working in collaboration with Richard E. Gies, lead volunteer of the Longwood Gardens Bluebird Project, Smithsonian Gardens established an Eastern Bluebird Habitat trail around the perimeter of the Greenhouse facility in Suitland MD.
A native songbird, the Eastern Bluebird (Sialia sialis) is a member of the thrush family (Turdidae). They eat insects and berries and require open grassy areas and meadows with low groundcover for feeding. These beautiful birds breed in all eastern states from Maine to Florida. They are considered to be secondary cavity nesters in that they traditionally nest in holes made by woodpeckers and other birds.
The nesting boxes were installed to benefit an existing population of Bluebirds as well as to encourage more bluebirds to nest on site. Eastern Bluebird populations are on the rise thanks, in part, to efforts like this one. The lack of suitable nesting cavities caused by changing land use patterns, increasing urbanization, and competition from introduced European starlings and house sparrows has been responsible for the decline of Eastern Bluebirds populations in the past.
When is a pair of nesting boxes better than one?
In areas where Eastern Bluebirds coexist with Tree Swallows (like Maryland) it is recommended that two boxes be placed 15-20 feet apart. Tree swallows will select one box for nesting and defend the other against use by other swallows thereby allowing Bluebirds to claim it.
A Green Roof: for style and comfort.
The roofs on these nesting boxes have been planted with a variety of stonecrop (sedum) plants. The purpose of the “green roof” is to help keep the interior of the boxes cool during the hot summer months.
The temperature inside these nesting boxes will be monitored in an effort to ensure the safety of the fledglings (baby birds).
The green roof nesting boxes were designed Richard Gies for Longwood Gardens. You can download a PDF of his instructions here:
