You may have noticed some new faces in our Blanding’s Turtle Conservation Lab, that’s because we have taken in a new group of Blanding’s hatchlings to headstart.
It all began a few months ago, when our Biology team and Dan Thompson of the Forest Preserve District of DuPage County went out into the field to track down some gravid Blanding’s turtles that were ready to lay their eggs. Each turtle has a tiny radio transmitter attached to her shell which gives off a unique signal so using a receiver we can track them. After locating them, the turtles were put into secure laying pens so they could lay their eggs in safety before being re-released. The eggs were then collected and put into an incubator to hatch.
After a couple of months, the tiny turtles began to emerge from their eggs.
It was about at this same time that our 2014 hatchlings reached the point where they were ready to be released into the wild. So, a few weeks ago, our Biology staff, along with Dan Thompson, released 60 of our 2014 Blanding’s hatchlings into the wild. We kept 24 of the 2014 hatchlings (some of which you can see in our Blanding’s display tank in Mysteries of the Marsh), and have introduced 106 2015 Blanding’s hatchlings to the Conservation Lab.
The majority of turtle predation takes place as eggs or during the first two years of life. By giving the Blanding’s hatchlings a "headstart" at the Museum during this vulnerable time, we are increasing their chances of survival. Although our Animal Care team works hard to provide them with this headstart, we don’t want the turtles to become habituated to humans. In order to reduce the risk of this happening, our biologists keep handling to an absolute minimum and the turtles that are on exhibit at the Museum are behind one-way glass. This is all part of a larger effort, in collaboration with the Forest Preserve District of DuPage County, to help restore the population of this endangered, native species and help re-establish ecological balance to the area.
