Hello Dear Readers!
I’ll be honest: I’m a little preoccupied with present-day bird tracks. I look for them when I’m on walks. I look for bird tracks when I take my recycling to the depot at the dump (the open pond sewage treatment area is there as well, sometimes attracting shorebirds and always attracting ducks and ravens.) Some opportunities I can anticipate, especially the outside-based ones. Others I stumble across.
The Fledgling Idea
I had the opportunity to visit an elementary school classroom, and saw the most amazing thing. There was a small box with a heat lamp. Inside came the heart-melting peeping of baby chickens. Sure enough, this elementary classroom had received chicken eggs to incubate as part of an experiential learning project of the life cycle of a chicken and birds in general. Once the chicks reach a certain age, they go back to the farm from where the eggs came.
So I started thinking…
If a classroom or an outdoor group has the opportunity to raise chickens (or other farm birds), they have the chance to see these birds grow from floofy baby chicks to adult floofy adult chickens. Baby birds grow quickly: they need to because even the precocial chicks (able to run around soon after hatching) are vulnerable to predators. There have been some studies on how present-day baby birds change size and shape as they age, this kind of study hasn’t been done on their footprints. One of my Ph.D. committee members had the idea of raising chickens to collect this data. Unfortunately, I currently live in an area where the rules on in-town chicken-keeping aren’t clear. But short-term science projects in a school setting are different than residential agriculture.
I asked the teacher “What would you think about adding a footprint-based science activity with these chicks that would be used in a scientific study?” We exchanged information (they thought it was a good idea) but unfortunately I not able to get this test project launched. I never heard back from the teacher (they likely already had a ton on their plate) and the chicks went back to the farm…but it did give me more time to think about the project.
The Project “Chicken Tracks” is a workbook that will lay out, step-by-step (pun completely intended) how to collect, record, and make replicas of tracks of chickens (or any domesticated farm bird). The workbook will describe the same procedures that I use to collect data for scientific publications. Ichnology (the study of tracks and traces) is, in my experience, extremely accessible. Sure, as a subject in science it comes with its own particular jargon and methods, but the act of collecting the information just takes careful practice and consistency.
Interpreting that information is where ichnology gets complicated. When we look at fossil footprints and trackways, it’s always important to remember that they were made by living, breathing animals. The nice part of looking at the tracks of present-day animals is that we can actually watch the animals make the tracks! Being able to watch animals make tracks connects, us as observers of the natural world, to the animal’s life and behavior. It’s easier to connect to tracks, to make interpretations about the animal that made them when you can see the animals in action.
At this point, the “Chicken Tracks” activity book is in progress. It contains basic introductory information, information sections for instructors, equipment lists, data collection sheets, and of course the how-to sections. There will be (as my artistic abilities allow) diagrams and cute pictures of baby chicks and other birds. Ultimately, the data collected using “Chicken Tracks” will be a citizen science data pool that will be used in studies on bird and dinosaur footprints. Progress on “Chicken Tracks” has been good. At this point, I’m figuring out all of the different steps of the activity that will make the written instructions (already completed).
While I hope that Chicken Tracks will be a useful (and fun!) science project for classrooms, it has been an invaluable exercise for me! There’s nothing like teaching others how to do A Thing to really understand what you know (or don’t know!) about A Thing. It also highlights all of the parts of ichnology and bird that I (over a decade’s worth of experience working in ichnology) might take for granted as being “common knowledge.” These things are common knowledge to me. They are common knowledge to my colleagues. But what about someone who is interested in animal footprints and footprint identification and wants to learn more and wants to be involved in the science of ichnology? That’s who “Chicken Tracks” is for.
I’ll keep you posted on when “Chicken Tracks” will be ready! If you have any questions in the meantime, please let me know in the comments!
