When Is A Whooping Crane Not A Whooping Crane?

Along the Central Platte River in Nebraska, there is an annual congregation of hundreds of thousands of sandhill cranes during the month of March.  For about two decades or so, there has also been a single whooping crane that appears to arrive and depart with those sandhill cranes.  There are various theories about why the whooper hangs around with sandhill cranes instead of its own kind, but most of us assume it is unaware of, or possibly uninterested in other whooping cranes.  We’re not really sure where it goes during the rest of the year, but it always shows up when the sandhill cranes come through each spring.

This whooping crane has been hanging out with sandhill cranes for about 20 years or more – assuming it’s the same bird each year.  It certainly stands out in a crowd, doesn’t it?  Unfortunately, it’s not the crowd it’s supposed to be hanging out with.

It’s kind of a sad situation, but does give visitors to this part of the state an improved chance of seeing a whooping crane.  Most whoopers migrate through this area later in the spring, after the sandhill cranes (and the crowds that come to watch them) have left.  A fairly small percentage of whooping cranes stop at the Platte each spring, and those that do stop are usually just here for a night or two, making it unlikely that many people will see them.  By contrast, the “lonely” whooper often stays for a few weeks or more, making it pretty accessible to grateful crane watchers.

As I was driving out for an early morning crane tour last weekend, I was thinking about the lonely whooping crane.  It had been hanging around near our viewing blinds along the river’s edge over the last week or two.  I knew there was a good chance we’d see the whooper on the river in front of our blinds (and we did!) but I was also thinking about something else.  What if the whooper left the river while we were in the viewing blind and landed in the grassland between the blind and where our vehicles were parked?  Since it’s a federal crime to disturb an endangered bird, we might be stuck in the blinds for a few extra hours, waiting for the whooping crane to leave.

When we first snuck into the blind, it was mostly dark, and most of the cranes were still asleep. We thought we saw something white in the sea of gray, but we had to wait until the light got a little stronger before we were sure of what we were seeing. The other two photographers with me had lenses longer than my arm (more on that later this week). This shot was taken with my puny little 18-300mm lens and then cropped liberally to make the whooper look bigger than a little white dot.

That discomforting thought led me down a rambling philosophical journey as I drove (did I mention it was early in the morning?) about whether or not that lonely bird should actually count as a whooping crane.  By law, of course, it does count, and there’s no question about that.  But what about in an existential sense?

The endangered species act is supposed to help populations of rare species recover, right?  We’ve added layers of protection for the remaining individuals of those rare species so they can survive and reproduce, increasing the size of their population.  But what if an individual is separated from its kind and doesn’t even recognize what it is?  If our lonely whooping crane has no chance of ever interacting with other whoopers, let alone reproducing, how should we categorize it?  Whooping cranes in zoos are physically removed from the wild population, but still have the potential to breed and create more whoopers, which could potentially be returned to the wild at some point.  The lonely whooping crane doesn’t seem to have that possibility.

After it woke up and stretched a little, the whooper wandered slowly upstream a quarter of a mile or more before we lost sight of it. It seemed to be walking completely alone – not following other birds. The sandhill cranes didn’t seem bothered by it, but also didn’t seem to interact with it in any way.

Now, I want to be clear that I’m not saying the lonely whooping crane isn’t important, and I’m not advocating that it be somehow removed from its protected status under the law.  I just found it interesting to think about what it means to be part of a species.  Do you have to be a contributing member?  Is reproduction the way animals pay dues to their species?  If our lonely whooping crane isn’t really a whooping crane, what is it?

I can’t emphasize enough how early it was in the morning when I was thinking about this.  I often do my best thinking while driving, but I’m not sure this counts.  Also, I honestly feel grateful to have the opportunity to see whooping cranes (including this one) fairly regularly during their migration, and I probably shouldn’t take that for granted.  However, being grateful doesn’t mean I can’t allow my mind to wander into the realm of whooping crane existentialism, does it?

Photo of the Week – March 16, 2018

Ok, here’s a little nature puzzler for you.  In today’s post, I’m including three photos from 2017 that have something in common.  Are you sharp enough to figure it out or will you need someone to point it out to you?  (Hint, the answer is not that they are all animals, live in prairies, or have legs and eyes, though all of those are true.)

These red beetles are often found feeding on milkweed plants.

This speedster was photographed in the Nebraska Sandhills.

This beetle is one of many insect species that often feed on the pollen of sunflowers.

Given the level of expertise within this blog’s readership, I figure someone will come up with the answer a few minutes after I post this.  If you think you know the answer, please put it in the comments section.  I’ll keep an eye on the comments and reply when someone’s got the answer I’m looking for.  Have a great weekend!
