Timelapse Bison Photos

Regular readers of The Prairie Ecologist are familiar with our timelapse photography project at The Nature Conservancy’s Niobrara Valley Preserve.  With the help of Moonshell Media, we set up nine timelapse cameras to capture the recovery of the Preserve from a big wildfire that swept through in 2012.

The cameras are supposed to be taking a photograph every hour during daylight hours to document what happens in front of them.  However, during 2013, we had a few issues with the cameras that led them to take photos much more frequently (and then run out of space on the memory card).  That led to some gaps in our coverage, but the silver lining is that it also gave us some very nice series of photographs over some two to three hour-long periods.

Twice during those frequently-photographed periods, bison were in the frame.  Below are two very short videos made from those photo series.

In the first video, the camera was set to record a blowout area – a site where the sand is destabilized and blown by the wind.  Blowouts are generally disliked by sandhills ranchers because they lack forage and tend to spread unless they are excluded from grazing and allowed to “heal”.  On the other hand, blowouts are ecologically valuable because of the habitat they provide to a wide range of species including plants (including the federally-listed blowout penstemon), tiger beetles, lizards, and many more.   This video shows that blowouts are also attractive to bison.  The video runs from approximately 7:30am to 10am on June 28, 2013.

We put one camera high atop a tall windmill tower to capture a landscape view of burned sandhills prairie.  During this video, the same herd of bison shown above wanders through the frame during a two and a half hour period on the afternoon of October 8, 2013.  As you can see by the color of the vegetation, most plants are in or near dormancy by this time of year, so the bison are picking and choosing what they can find to eat.  The bison at the Preserve get themselves through the winter without supplemental feed from staff, so October food is probably pretty attractive compared to what’s available in February…

These short bursts of timelapse video were not the expected product of this project, but have turned out to be some nice bonus coverage.  Fortunately, the gaps caused by full memory cards are not long enough to seriously disrupt the bigger story of long-term recovery.  I’ll continue to bring you that story as it emerges.

 

2014 Sandhill Crane Migration – Platte River, Nebraska

March is always a busy time on Nebraska’s Platte River.  It’s the beginning of prime prescribed fire season, of course, and a good time to work on fence repair and tree clearing projects.  But there’s no question that sandhill cranes rule the month.

About 600,000 sandhill cranes spend a good portion of late February, March, and early April along the Platte River before heading north to nesting grounds.  It’s one of the greatest migratory phenomena in the world, and it happens right in our backyard.  Because of that, our staff spends quite a bit of time taking groups of people into our viewing blinds where we watch the cranes land on the river at sunset and take off again in the morning.  It’s an important fundraising opportunity for The Nature Conservancy, and a way to show our Nebraska members what we’ve been working on and thank them for their support.  It’s really gratifying to watch the reaction of people as they see the crane spectacle for the first time.

My son Daniel got his first trip to a crane blind on his birthday this year.  It was very cold, but he was still glad to go.

My son Daniel got to take his first trip to a crane blind on his 10th birthday this year. It was very cold, but he still had a great time.

Because I’m in the blinds fairly frequently, I get quite a few opportunities to photograph cranes – though the number of nights and mornings when the light is favorable can be limited.  Also, I’m really not a wildlife photographer, either in terms of my equipment or aptitude.  Despite that, I usually end up with a few decent photos by the end of each season, though not as many as I should.

This year, I also tried to get some video footage of the cranes – something I have even less experience with and aptitude for than wildlife photography!  Also, my only video camera is the video function on my Nikon D300s SLR camera, and I’m still learning to use it.

You can see two of my attempts by clicking on the links below:

Video 1 – Cranes preparing to leave the river on a cold morning.  This 30 second clip gives you a feel for the density, activity, and noise of a crane roost.

Video 2 – Cranes chasing each other around on a sand bar.  There is a lot of jumping and chasing among cranes.  Some of it is courtship and pair bonding, some of it is just posturing.  This clip is about 30 seconds long.

In the evenings, the cranes often wait to come to the river until it is getting dark, making photography difficult.  In those cases, the best photo opportunities are usually silhouettes of the birds against the sky as they drop into the river.  On nights when the light is nice and our guests are fully engaged watching the big event, I manage to snap off a few shots.  Both close-ups on a few birds at a time and more wider views can be attractive.

This year, my favorite image was the first shot I took one evening.  The sunset was beautiful and the cranes were parachuting gracefully toward the water as I poked my camera lens out the window of the blind.  The resulting photo reminded me of the theme song to a 1980’s TV show – The Greatest American Hero.

Bonus Coverage

On one of the crane tours I led this spring, I met 11-year-old Jack McDowall and his dad.  Jack is a fellow blogger who is working on a year-long project to photograph and document his bird sightings.  I think many of you would enjoy his photos and the natural history information he includes along with them – including a post from his trip to our viewing blind.  If you’d like to visit his blog, you can link to it here.
