All About A Turtle!

Earlier this week I noticed a red-eared slider crawling across the yard at a pretty brisk pace.  Rick had rescued one from the road a few days before and considering it was the same size, we assumed it was the same one coming back across the yard.  When it got to where the ground slopes up to the driveway, it stopped.  It kicked up some leaves for a bit and quieted down.  Rick and I named the turtle “Gary” and joked that if we fed it maybe it would hang around the house for a time.  Every once in a while we get a turtle.  The people two doors down have a small pond that usually dries up early in the summer but with the amount of rain this spring the little depression still had water.

I decided to go out and see what Gary was up to and noticed that he had dug a shallow pit and lowered himself down into it.  Having some suspicions I googled “red-eared slider” and found a surprisingly similar photo of what I had just seen on the turtle’s Wikipedia page.  It seems that we needed to come up with a new name for Gary!  We picked "Geraldine." 


Geraldine digging a shallow hole to lay her eggs.

Red-eared sliders are native to Texas but can be found globally where they are considered an invasive species.  Nesting occurs from April to July so Geraldine seems to be right on target.  Female red-eared sliders can lay anywhere from 2-30 eggs in a single clutch.  We stayed away from her during the laying process so we didn’t actually see any eggs.  So in 59-112 days (the incubation period) we’ll have our answer!

The whole process took a little over three hours.  Geraldine hurriedly covered the nest site moving leaves and mud.  After, she crawled away heading back towards the little pond two yards over.  Upon inspection, the nest site is remarkable hidden and well covered.  No trace of disturbed soil remained.  Leaves were pushed over the site and the only way I could tell the location of the nest was looking for a piece of spinach I had left out earlier (thinking the turtle was hungry, not getting ready for egg laying!).

Leaving the nest site.  Nest is located in the shady front left corner of the photo.


We’ve marked the nest with a ring of small stones so we can keep track of the location.   And on our calendar July 18th is marked as “turtle birthday”!  Actually it could be anywhere from July 18th to September 19th for the 59-112 day incubation period.  That’s a long time to wait!  Hopefully we won’t have any hungry predators around the yard so Geraldine's offspring can make it to the little pond down the road, too.

What To Do Now That The Spring Rush Is Done?

Another April has gone and with it all the TMN weekend activities like Earth Day, BioBlitz, and the Hazardous Waste Clean Up.  You might be asking, what can I do to still be active?  Why, you can become a Citizen Scientist!


Who are Citizen Scientists?

Citizen scientists are regular, normal people that contribute to scientific research projects.  Volunteers from all over the world make observations and enter the data online.  These reports can be from dedicated trips to local natural areas or just documenting what’s crawling through the backyard.  Depending on the project, it can be as easy as taking a picture of an insect and recording the location where you found it.

Why Participate?

Citizen scientists help the scientific community in two ways.  They collect data that would take the researcher years to gather and at a much lower price… for free (in most cases)!  Need to collect data from all 50 states and you only have a year to do it?  Call out the citizen scientists!  The data that is gathered can be used to look at trends showing the behavior of a species over a large geographic area.  The Lost Ladybug Project, for example, seeks to study the recent decline of native species in North America.  The particular researcher in charge may have spent his or her lifetime amassing data for this project and thousands of dollars for traveling from place to place to make observations. But with an army of citizen scientists, the data collection phase of the research is quicker leaving the scientist more time for analysis. 

Now, becoming a citizen scientist is easier than ever!  All you have to do is find a project that interests you and sign up online.  There might be some initial training but beyond that, when you make your observations is up to you.  For most projects data collection is not a structured event (with the exception of some birding events) but it’s something you can do on your own time that best fits your own schedule.

Think you need to be a specialist to be a citizen scientist?  Nope!  You don’t have to be an expert in the field, just someone with a desire to learn more about the topic.  Most projects have experts that will check your entries to verify your record.  Some even have help sites to identify your unknown species.  Researchers that rely on citizen scientist observations know there is a learning curve and everyone needs help and practice.  These researchers want citizen scientists to participate so they can get their data!  More participation means more data, which will give the researcher a more complete answer to their scientific question.


Become a Citizen Scientist!  Websites to Get Involved:

These are really just a FEW of the citizen scientist projects out there!  Some will count for TMN volunteer credit and others will not.  But really, participation in a project should be about learning more about the topic or wanting to be a part of something big.  

Several sites are included with the Texas Nature Tracker Program from Texas Parks and Wildlife.  Projects include: the Biological Inventory Team Project, Box Turtle Survey Project, Texas Amphibian Watch, Texas Black-tailed Prairie Dog Watch, Texas Horned Lizard Watch, Texas Hummingbird Roundup, Texas Mussel Watch, Texas Whooper Watch:
