Tetrapod Collection: What Happens in a Collection?

A collection is nothing without people who use it. Our collection sees constant use by students, artists, researchers, experts and more. We conduct tours, workshops, and projects within the collection, all involving people who desire to learn more about some animals and find these in our collections. None of this would be possible without a community around us, who want to learn and appreciate all the collection has to offer.

Help us maintain our specimens and check out our campaign! We are raising money for a new mobile cabinet for our endangered and extinct species. Please spread the word about our campaign and and donate today!

How can museum collections help us understand bird migration?

Millions of birds migrate south every fall. You may have noticed some recent changes in your backyard bird community. Most of our summer residents have left by now, Tree Swallows and Eastern Bluebirds will be back next spring. Some birds will not succeed on their long journeys, because we have put up many obstacles for them to overcome, such as buildings with clear, shiny windows. Birds try to fly right through them. Thousands of volunteers like you pick up these window-killed birds and take them to their local natural history museum. We prepare them into specimen skins and preserve them for future research.

Over the years these specimens paint a picture of certain routes particular species take, the timing of their migration etc. We have learned that not all individuals of a species migrate at the same time, often young birds migrate later than adults, females differently from males.

To find out when to expect migrating birds in your area visit the Black Swamp Bird Observatory. We can learn so much from our museum bird skins and studies will help us make migration safer for today’s birds.

Sometimes birds get blown off track on their long journey and end up in an unusual location. With so many bird watchers today, these birds usually stir quite a bird watching frenzy. In the past some of them have ended up in our collection like this Magnificent Frigatebird that Milton Trautman collected in Morrow county, Ohio on October 2nd in 1967, almost 50 years ago.

Natural history museum across the country help with these efforts. Read about this student’s project “What can we learn from 30+ years of bird migration data?” at the Field Museum in Chicago.

Before you get involved you may want to read this testimony from volunteers at the Field Museum who collected and prepared many of the specimens for the above study.

Where’s Waldo?

While reading our “Meet the Staff” post, you probably saw that the term “geo-referencing” came up a number of times. What does geo-referencing mean and what purpose does it serve in a museum? It’s a fair question since geo-referencing isn’t exactly an everyday activity, yet it plays an important role in the digitization of our collection.

Here’s the scenario: you’re sitting at home and hear a very loud smack. You go to see what happened, and find a bird has slammed right into your window. The bird is dead but you know a place where it can live on forever, the Museum of Biological Diversity’s Tetrapod Collection. You put the body in a freezer bag and take it over to the collection in order to donate it. This is known as salvaging and the whole process begins with that one action. If you have more questions there is a whole webpage devoted to the contribution of specimens to the Tetrapod Collection.

After our preparation lab assistants prepare a bird, it is given a label, a number, and is entered into the database. In the database we enter in the name of the collector, when it was collected, the species name, and the location. However, we can’t simply just put an address in for the location, we need to be much more thorough than that. We use latitude and longitude in order to map out points where our specimens were found. It helps build a species list of an area and maintain consistency when landmarks are removed or names are changed. In short, it reduces the uncertainty of a location.

Having a specimen with latitude and longitudinal points clears up some of the following questions: For instance, a bird crashed into your window. What side of the house did the bird hit? Was it the north side, or was it the east side? How far from the house was it? Two feet? Maybe three? Sometimes a person can’t really give us information that is too specific, but we can still work with a general location given with a specimen. We’ll simply find the area that the specimen was found so we can use varying degrees of uncertainty that depend on the specificity of the locality provided.

Geo-referencing is a common practice among scientists and research collections such as ours. Thanks to modern technology, we now have the ability to more accurately map out the presence of a particular species and assess the population’s health with more certainty. There are many times when scientific discoveries or conservation efforts rely on citizen scientists such as you making an interest in what we as a scientific institution do. Contributing a deceased specimen to a museum like ours counts as one of those times.

Curator of tetrapods

As the curator of the tetrapod collection I am often being asked what the collection is used for and who uses it. The answer is simple, specimens are used for research and teaching as well as art projects and the users come form a wide range of agencies, organizations, schools and universities.

So what are tetrapods anyway? For those of you who speak Greek or Latin, this is no mystery, tetra means four and pedes means feet, so all animals that have in their current or ancestral state four limbs. Yes, birds are included too, wings being their second pair of limbs.

How old are the specimens? Some of them, especially among the birds, are from the 18-hundreds, others are very recent. Just today an American Woodcock was added to the collection. Not quite added yet, this bird must have hit a window and died, so we put it into our freezer where it joined hundreds of other birds that are awaiting their promotion to museum specimen.

You will learn about techniques how we prepare birds and other animals in some later posts.
