Our Blanding’s project deals with several hundred turtles in numerous different locations and if we are not careful, the individual identities of the turtles can quickly get mixed up. So how do we stop that happening? Those of you who are dog owners are probably already familiar with ID chips. We use a very similar thing for our turtles.
These are the tools we use. The ID chip is about the size of a grain of rice, the syringe has a hollow tip to hold the chip and the tweezers hold the skin of the turtle as the chip is inserted. The turtles’ skin is quite loose just in front of the hind leg so this is the location of choice for inserting the chip. As with anything slightly invasive that has to be done to a turtle you get one chance only! One chance to grab the leg before it is pulled firmly into the shell and one chance to get hold of the skin before the turtle clenches up and that loose skin miraculously disappears!
Luckily for us it appears the turtle doesn’t bear a grudge for long so if we miss at the first attempt, we put the turtle back into the water, go on to the next one and then come back to the original turtle to insert the chip. Once the chip is inserted we scan the turtle and read off the ID number. This is a multi digit and letter sequence that will immediately let us know which turtle we are working with.
Some of our turtles go directly from the museum out into the wild but we can’t afford to put radio transmitters on all of them so this is a great way of knowing which turtle is which should we come across them a few years later. This is such a precious species, we want to be able to use as much data as possible when we find an individual so being able to identify them, of course, is vital.
