Photo of the Week – August 3, 2017

Quick note on this Saturday’s Field Day.  We will be there rain or shine, and have indoor presentations , if needed, if rain keeps us from seeing insects outdoors during part of the day.  Please come join us for this free event!

All of a sudden, painted lady butterflies have exploded onto the scene here in central Nebraska.  They are fluttering around all the flowers in our yard and are abundant in our prairies as well.  Painted lady butterflies are migratory, but this latest flush isn’t due to a new set of arrivals from further south.  Instead, a new batch of adults has just emerged after spending the last several weeks as caterpillars in prairies and other locations – including soybean fields.

In soybean fields, the caterpillars are known as thistle caterpillars and feed on the leaves of the bean plants.  According to my father-in-law Orvin Bontrager, a long-time agronomist, they don’t usually do enough damage to impact yields, though the damage can look a little scary to farmers.  For the rest of us, there’s nothing scary about these welcome accents to wildflower patches everywhere.  Here are a few more photos from this week of painted ladies in my yard and nearby prairies.

(Fun fact – painted lady butterflies are found on every continent except Antarctica and Australia.  They also some make migratory flights that make monarchs look like amateurs.  Speaking of monarchs, they inhabit a larger slice of the earth than you might be aware of too…  Don’t get me started, I could spout insect trivia all day!)

Photo of the Week – March 26, 2015

Despite snide comments from certain friends, I do – now and then – take photos of subjects other than insects and plants…

As I write this, the annual sandhill crane migration phenomenon is taking place on Nebraska’s Platte River.  The river valley abounds with tall gray birds feeding in crop fields and meadows and the sound of calling cranes fills the air.  I haven’t had a lot of time for crane photography this year, but have managed to pull the camera out of its bag a few times.  A couple weeks ago, for example, I was in a riverbank viewing blind with a group of birdwatchers, watching cranes coming in to their river roost against a rose-colored post-sunset sky.  The muted light made photography difficult, but I managed a few photos, including the one below.

Sandhill cranes landing on the Platte River, where they will roost overnight.  Because of low light levels, this photo was taken with an ISO of 2000, making it relatively grainy.

After the light and color faded a little more that evening, I decided to try a short video.  If you have never been to the Platte River during this time of year, this will give you a tiny glimpse of what it’s like to watch cranes coming to the river in the evening.

Watching cranes drop into the river at sunset is fun, but I prefer to visit them in the early morning as the roosting birds start to wake up and get ready for the day.  We have to sneak into the blind well before daylight and it’s often difficult to tell how many birds are on the river until the growing light slowly reveals their shadowy outlines.  On a good morning, we may have 10-20,000 birds or more within view as the sun comes up.  The sight and sound of those birds is astounding.  As the sun rises and the air warms up, the activity level of the birds increases, and we get to see a great deal of social behavior – preening, pair-bonding and courtship “dancing”, and aggressive posturing.  The short video below documents that kind of increasing activity through one morning this spring.

I am grateful to have a front row seat to an annual ecological phenomenon that draws birdwatchers and nature lovers from around the globe.  The sound of sandhill crane calls is a pretty great soundtrack to my spring.  The only regret I have is that the majority of crane-watchers never get to see the Platte River Prairies during the summer when – though we have no cranes around – our grasslands are teeming with the sights and sound of birds, insects, flowers, and generally spectacular prairie life.  Please come visit!
