Photo of the Week – March 19, 2015

Proof that I’m a biologist:  While driving along a gravel road near our shop this week, I stopped and backed up to see if I’d seen a small snake or just a piece of debris in the road…

A redbelly snake (Storeria occipitomaculata) found in Hall County, Nebraska.

I’m glad I stopped.  It turned out to be a redbelly snake, a species found in only a few counties in Nebraska.  I think it’s the third one I’ve found in our Platte River Prairies, dating all the way back to when I was working out here as a graduate student in the early 1990’s.

Not a lot is known about the habits or habitats of redbelly snakes in Nebraska.  When I got home with some photos, I contacted herpetologist Dan Fogell to confirm the identity of the snake and learn more about it.  Rather than getting a lot of information from Dan, he instead peppered me with questions about where and when I found the snake because he’s trying hard to gather data and better understand the species.

This was a big snake (for a redbelly). It was close to 11 inches in length, which is about the maximum size for this species.

 

Jasmine (one of our Hubbard Fellows) held the snake to show the colorful underside it is named after.

This particular snake was on a gravel road between two crop fields when I happened upon it.  The road ditches were full of old matted-down smooth brome grass.  It didn’t seem like particularly friendly habitat for wildlife.  Was the snake living in those ditches?  Or traveling to other habitat?  There was a small woodlot a couple hundred yards away, and a stream across the cornfield to the north…  We released the snake where we found her, so whatever habitat she’s looking for, I hope she finds it.

There are a lot of species we just don’t know much about – not just tiny invertebrates, but also relatively large (and beautiful!) vertebrates.  It’s another reminder of how important the collection of basic natural history information is.  Conservation is difficult, but even more so when we don’t even know much about the species and natural systems we’re working to conserve.

I’m grateful that I had the opportunity to see and admire this snake.  I hope my kids get the same chance.

Photo of the Week – March 6, 2015

Ok, it’s not a world class photo from an artistic standpoint, but it tells a story.  I just wish I knew what the story was…

Hot cross buns?

Hot cross buns?  Little mounds of snow apparently pushed up by a small mammal tunneling beneath the snow.   Restored prairie at Deep Well Waterfowl Production Area, west of Aurora, Nebraska.  February 2015

I noticed these two small mounds of snow last month in a restored prairie west of town.  I was scurrying around with my camera as the sun dropped quickly toward the horizon, hoping to get some photos before the light disappeared.  The mounds were maybe 3 inches in diameter, and when I looked straight down at the left one, I could see a small tunnel leading straight down.  If I hadn’t been distracted by the fading light and my self-imposed urgency to use it photographically, I would have done the smart naturalist thing and dug around to see what the tunnels looked like.

My guess is that these were formed by a tunneling vole that needed to push some snow up and out of its tunnel, but I’m not sure I’ve seen this before.  There were no tracks above the snow that would have indicated a deer mouse or other similar creature.  Any other suggestions?
