The Carcass



In other trips to Yellowstone, I had heard people talking about watching wolves on a carcass, but we had never had that opportunity.  On our September trip, many park visitors experienced the wonder of bears and wolves as they fed on the carcass.  The first few days, only the grizzly bears fed.  We heard at one point there were five grizzlies on the carcass.  We passed by every day, usually stopping to spend time.  On the last day we could finally see the skull to identify it as a bison carcass.

The prime viewing spot was at my favorite overlook at Hayden Valley.  Each day there were cars lining the valley - some at better vantage points than others.  There was also an active wolf den at the north end of the valley.

I had both my scope and my Sigma 300-800mm lens focused on the activity.  The carcass was on the other side of the valley from the road - Henry used Google Earth to estimate the distance at 3/4 of a mile.  It felt farther.  The scope can get you visually closer, but I don't have a good digiscoping system set up yet.  But when you crop in on photos with the 300-800mm, you at least have some good "memory" shots of the event.





In our early years of visiting Yellowstone, we didn't have a good scope. I was always grateful when people would generously allow me to peak through their scope.  While I don't have one of the expensive scopes, I now have a decent one.  It is my pleasure to pay back those people from my past by allowing other people to look through my scope so they too can see this marvel of nature in much better detail than their eyes or binoculars allow.

Nature's Tragedies









My husband called me out of my office to check something outside. He led me out by the fig trees to a small carefully excavated hole.  "What is this?" he wanted to know.










There were white fragments. At first glance I wondered if they were crawdad pincers.



 











Upon closer examination they were small, brittle eggshells. Henry wanted to know what the was the story here.  We wondered if this was evidence of turtles hatching out or what. He had his phone on him so I asked him to take pictures.





I have a Facebook/blogger friend that I thought would know the answer.  Naturalist writer and artist,  Julie Zickefoose, is someone I thought would be able to read and interpret this nature story. Sure enough she wrote back that it WAS a turtle nest that had been dug out by a skunk or raccoon. Since I've seen a raccoon in the back yard recently, I'm guessing he is the culprit. An additional email confirmed that it was either a box turtle nest or a snapper turtle nest - probably the snapper turtle. When baby turtles hatch and leave the nest they only leave a very small hole - not one with piles of dirt and tailings.

Julie says that every time she sees a turtle laying eggs, she covers the nesting area with a cage to protect the turtle eggs so they can hatch. I'm not sure we've ever seen a turtle laying eggs although we see them regularly on the pond.

I suspect we will try to be more observant during turtle egg laying season in late spring and summer.  I also realized that I need to work on my turtle identification of the turtles I see in and around my pond.

The Butterfly's Demise

As I sit on my porch this year, we've had more butterflies than I remember from other years. Because we live in the country, we don't do a complete mow until the widlflowers have seeded out. So I've been enjoying watching the butterflies flit from flower to flower. One morning, I saw a butterfly near the horsemint bloom. One minute it was fluttering gracefully along. The next minute the wing beats were struggling and the butterfly was dangling upside down. I knew instantly what had happened, the butterfly had been attacked by a spider. The butterfly hadn't got stuck in a web, rather the spider had somehow bitten the butterfly as it was near the bloom. With my binoculars, I could see the small spider on the butterfly's body. The butterfly went limp and swayed in the breeze held by one strand of the spider's silky web thread. On one level, I should have gone and gotten my camera with a macro lens. It was certainly high drama. I'm pretty sure the butterfly was doomed from the first moment I saw its distress.Once the spider's venom paralyzed it, I'm pretty sure it couldn't have recovered. I don't think I could have changed the outcome even if I had tried to intervene. On one level, I'm ok with the spider getting its needed nourishment. It was amazing how that small spider could conquer the much larger butterfly. The spider was hiding inside the bloom of the horsemint, waiting patiently for its opportunity. How amazing is God's creation.

But another part of me grieved a little, because like most of us, I value butterflies more than I value spiders. I did some web searching and found one article about spiders that said that while spiders are beneficial to humans because they eat insects, that people generally find them unsavory because they tend to lurk in dark places, they often have a grotesque appearance, and their toxicity has been exaggerated. Spiders are also prey for other animals - some wasps paralyze spiders and lay their eggs on the paralyzed body for their young's first nourishment.

I want to value and appreciate all of God's creation. But I have to confess that various critters that invade my indoor space do not always survive to tell about it. When practical, yes, I relocate. But things like mice, wasps on the exterior of the house, little moths invading the interior, scorpions crawling on the floor don't always survive their encounter with me. But it is truly amazing to me the variety of animal species, all with a different purpose and a different diet. Some things I appreciate more in their native environments, but I wonder if there aren't wider applications to this story of the spider and the butterfly even if nothing more than to appreciate something for what it is - even when our first reaction is negative.

One of the things that went through my mind was from the story of Jonah. When Jonah was upset because God was not going to destroy Nineveh because the people had repented. God sent a vine that grew and brought joy to Jonah when he was discouraged. A worm came and chewed the vine and it withered and died. Both the vine and the worm were part of God's creation - fulfilling their intended purpose.

Father, help me to see the world through your eyes. Help me to value all parts of your creation - from the smallest microbes to the largest creatures of the sea - from the beautiful butterflies and birds to the spiders, vultures and hyenas. Help me also to value the people in your world. Some people are like the spider - hard to like or love. Father, help me to look for the good in the people around me and to value them as you do.
