Best of Prairie Ecologist Photos – 2013

As promised, here are some my favorite photos from 2013.  It was really tough to narrow these down to 22 (it was going to be 21, but see below) out of the roughly 1,800 images that were “keepers” from my various photography jaunts this year.

Of course, many of you joined in the winnowing process by helping me decide between two similar bison photos last week.  Or at least that’s what was supposed to happen.  Since the vote was nearly evenly split (and a lot of people voted “both”) I decided to include both photos.  You’ll see them displayed back to back below.

I hope you enjoy the photos.  If you let the slideshow run on its own, it’ll take a little under two minutes to cycle through.  You can speed up the process, if you like, by clicking on the arrows within the frame.

If I had to choose a single favorite from the year, it would probably be the one below.  It tells a great story without having to use any words at all.

I shot quite a few images of crab spider silhouettes that morning, trying to get one that was just right.  I got some pretty nice ones, but none that were as striking as I’d hoped – until I was photo bombed by this ant.  That’s often the way photography goes.  Equipment and technique are both important, but you really just have to be in the right place at the right time.

I’m looking forward to being in lots of right places in 2014.

Photo of the Week – July 3, 2013

Sometimes danger is waiting just around the corner…

An ant explores an annual sunflower for extra-floral nectar, seemingly unware of the crab spider lurking on the other side of the petals.  The Nature Conservancy’s Niobrara Valley Preserve – Nebraska.

Last summer, I wrote a post about annual sunflowers, including a short bit about how sunflowers secrete extra-floral nectar to attract ants.  The ants eat the sweet substance and may help repel potential herbivores from the sunflower in return.  As you might expect, however, an abundance of ants can also be a potential source of food for other predators – including crab spiders.  When I was at our Niobrara Valley Preserve last week, I noticed several instances where crab spiders were hanging around on sunflowers.  They probably weren’t waiting specifically for ants, but apparently ants are an acceptable prey item if they happen to be available (see below).

A crab spider feeds on an ant it caught on an annual sunflower.  This photo was taken a few minutes after the above photo, but it wasn’t the same sunflower, spider, or ant shown in that first photo.

…and that’s life – and death – in the prairie.
