A Bit of Batting Practice

For the WGNSS Nature Photography Group’s January outing we headed to Carlyle Lake in Illinois. Our primary target was the dam’s spillway. I have had a lot of fun at this location photographing Bonaparte’s Gulls and American White Pelicans during past winters and these species are what we were hoping for on this trip.

Being a spillway with the dam and infrastructure surrounding it, the backgrounds are definitely challenging; however, it is not impossible to handle. The images below showcase one method we could use to handle this situation. With the rising sun at our backs, I noticed the light was hitting these mostly white birds perfectly. By exposing precisely for the whites and a little exposure manipulation in post-processing, it was possible to turn the darker concrete walls of this section of the spillway nearly black, which allows the birds to pop off this background as seen in the images below.

Predicting the movement of birds in a typical winter is difficult and this winter, where seasons have been changing on a daily basis, is pretty much impossible. On top of that, water levels in the lake and spillway channel were a couple feet below normal. The spillway gates were releasing just enough water, which I believe limited the numbers and size of fish falling through. So, it wasn’t surprising that we found almost nothing but Ringed-bill Gulls (RBGU) fishing in the spillway.

Ring-billed Gulls are considered 3-year gulls, meaning that they have a plumage transition for the first three years of their lives before they develop into the typical adult plumage. In addition, there is considerable variation within these years, e.g. a 2 year old gull may look different from a 2.5 year gull. Given I am no expert, I have made some captions with my best guesses on the ages of some of these birds.

Another method of dealing with ugly backgrounds at this location is to focus on the fishing activities or other opportunities where the water will be the background of the image.

Many nature photographers would consider this a bust of a day and would perhaps head back home to watch a meaningless football game. However, I like to look at this as both an opportunity for practice and to potentially learn something new about a species taken for granted and usually ignored. I liken opportunities such as this to batting practice in three ways: 1) It gives you a chance to hone your skills – this is high-speed action photography with challenging backgrounds and dynamic lighting. If you haven’t mastered your camera’s exposure and autofocus settings, you will likely struggle getting the images you envision, 2) It’s a lot of fun! Whatever species you find in a spillway like this, there will likely by plenty of birds fishing, giving plenty of opportunities to capture those fleeting moments, and 3) with a species like the RBGU, you won’t likely come away with anything to brag about. These aren’t eagles or owls or some rare species that will be all the talk on social media.

I really enjoyed watching the gulls catch and position their fish in flight for the head-first swallow. I was fortunate enough to catch this in action in several of my photos – they literally give them a little toss and catch them again so that the head is facing towards their mouth. It was also interesting to watch a few who knew the fish was too large to ingest and subsequently released back to the water.

As I alluded to above, I had a lot of fun shooting these gulls. The feeding opportunities were not as plentiful as I usually find at this location, but by staying alert and ready I came home with some photos that I really like.

Ring-billed Gulls were not the sole fishers we found. We also had several first-year Herring Gulls shown below. Unfortunately these birds did none of their own fishing, but seemed content in attempting to steal the catch from the RBGU.

Thanks for visiting!

2025 Caterpillar Season – Harris’s Three-spot

Harris’s Three-spot
Harrisimemna trisignata fam. Noctuidae (Hodges#9286)
Host plant: buttonbush (Cephalanthus occidentalis)
Date found: ~16, Aug, 2025
Location found: Franklin County, MO
Click here to see the adult moth
Notes: Part spider and part bird dropping, this caterpillar is absolutely astounding. Note the empty head capsules that the caterpillar retains with each successive molt. It has been shown that these caterpillars use these to thrash at potential parasitoid wasps and flies that approach while attempting to deposit eggs on their would-be hosts.

Special thanks to Eva Wiedeman who found this individual in her neighborhood and brought it to our WGNSS fieldtrip at Council Bluff Lake. Photographing this caterpillar was a prime objective for me this season. Now I just need to find one on my own and hopefully a larger 4th instar!

Return of the Illinois Chorus Frog!

During this past weekend the WGNSS Nature Photography group met up with our friend Dr. Rick Essner from SIUE to see and photograph one of our favorite subjects, the Illinois chorus frog (Pseudacris illinoensis) . I first wrote about these wonderful little guys a couple of years ago when Rick helped a few of us see them for the first time.

This year’s visit was perfectly timed for my primary photography goal, which was to photograph this species during amplexus. Our first stop was at a sand-prairie habitat where the frogs use small plastic basins that are set into the ground in order to keep the standing water these frogs need to deposit eggs and the resulting tadpoles need for their development. In addition to these artificial basins, the land mangers at this and a nearby sand prairie tract have recently installed larger ponds with liners to retain water long enough to see the frogs through their development cycle without the need to worry about egg-predating fish. These ponds were only installed this winter, however, and cover-providing vegetation and structures in the water are not yet established. We only found a couple of frogs at these locations but hopefully these new ponds will support a strong breeding population in years to come.

WGNSS members and frog paparazzi, Casey, Dave and Miguel photograph a frog while a student collects measurement data on another.

Getting photographs was not the primary reason Rick and his students were out on this fantastic evening. The biologists at SIUE are using mark-recapture techniques to study population demography and spatial activity, as well as the frog’s feeding behavior, locomotor behavior, and diet. It was fascinating to watch the students insert the smallest available PIT (Passive Integrated Transponders) tags in order to identify individual frogs in order to monitor their growth, movement and other characteristics over time.

A student prepares to insert the PIT subcutaneously into the frog. Following the insertion, the puncture in the skin is sealed with Vetbond.
After the PIT has been inserted, the student checks that the identification from the transponder can be read and recorded. The frog now has an identity!

After finding a few frogs in the sand prairie, we followed Rick and his students to other potential locations that might contain breeding frogs. We found what we were looking for in a location that was somewhat unfortunate but definitely contained what the frogs were looking for. At a drainage ditch between a small blacktop road and an agricultural field we found a group that I estimated to be between 25 and 50 Illinois chorus frogs along with quite a few American toads (Anaxyrus americanus). Here we easily photographed pairs in amplexus and struggled to photograph calling male Illinois chorus frogs.

In order to photograph the frogs with inflated vocal sacs during their vocalizations, we first needed to find the solo males that were vocalizing. This was the first challenge. The unpaired males seemed to have a high preference for vocalizing under the cover of the short vegetation along the banks of the ditch. This made finding them quite a difficulty. Additionally, as anyone who might have the experience of attempting to find vocalizing frogs will know, they exhibit what could be called a ventriloquist effect. As the observer hones into the location where the frog must be calling from, it is simply impossible to find. This effect is hypothesized to be an adaptation to predation avoidance. A stationary frog, vocalizing at incredible decibels, could be seen as ringing the dinner bell for predators with the ability to use auditory cues to track their prey. This may help with predator avoidance, but then how does the female find her chosen mate with the sweetest voice?

Finding the vocalizing males was just half the battle. In order to photograph these guys at night, we must shine a light in order to focus on them. More times than not, as soon as I trained my focusing light on to one of them, they would quit calling. It would then take quite a while for them to get started again after sitting still with the lights out. It took me quite a few attempts to get the few successful images I was fortunate to get.

When male frogs are in a perfect situation such as this, they are eager for ANY opportunity. If it moves and in any way matches their search pattern – namely, any other frog, they are known to grab and hold on, whether that be a conspecific female or male, or sometimes something even more, shall we say, less evolutionarily appropriate…

This Illinois chorus frog was so randy that this American toad looked ripe for the picking!
On top of this interspecies attempt, the toad turned out to be a male!

That’s all I have to share from this wonderful evening. I’m happy to see that researchers at SIUE are studying this threatened species and that the land managers are making strong attempts at improving breeding habitats for this wonderful species.

Thanks for the visit!

Mirrors and Moonscapes – A Fun Return to Elephant Rocks

The WGNSS Nature Photography Group, led by the man with the great ideas, Casey Galvin, headed to Elephant Rocks State Park in Iron County, MO, for the group’s February field trip. Our primary target for the evening was to utilize the full moon to light our scene after sundown – images often referred to as “moonscapes.” This was my first real attempt at taking moonscapes; usually I am focused on low to no-moon nights in order to focus on stars and deep sky objects.

Reflections on Quarry Lake
ISO-50, f/11, 3.2 sec. exposure, 140 mm focal length

We arrived in time to have a walk around prior to sunset and the park’s official closing time. In order to be in the park after 5:00 pm, special permission must be made ahead of time. During our stroll, we made our way to the backside of the quarry lake – somewhere I had not been in many years. This turned out to be a serendipitous experience. There we encountered some very nice golden light and excellent reflections coming from the lake’s surface. Unfortunately, the winds were just strong enough to create some obnoxious ripples on the water, ruining the mirror effect I was going for. No worries, however; I added a CPL and a pretty strong neutral density filter (in order to increase shutter speed) to my mid-telephoto lens and the ripples magically disappeared.

Several abstract-like faces appeared in tight-compositions with the rock wall mirrored off the lake’s surface
ISO-100, f/9, 2.5 sec. exposure, 84 mm focal length
I find capturing enough saturation in lighter colors a challenge with digital cameras. I am finally learning how to recover this in post-processing. The pretty light helped showcase the pink granites that the St. Francois Mountains are known for.
ISO-50, f/11, 5 sec. exposure, 118 mm focal length
This one was too good to pass up the opportunity to make the face more obvious by orienting it vertically.
ISO-100, f/9, 4 sec. exposure, 73 mm focal length

Shortly before sunset, we headed to the other side of the park to hang out with the rocks that give the park its famous identity. The remaining images were all taken after the sun had set and were exposed using only the light of the February full “snow moon.”

Moon rising over Elephant Rocks

Somewhat surprisingly, care had to be taken when shooting with the full moon at our backs as the shadows were very noticeable!
ISO-3200, f/4, 6 sec. exposure, 20 mm focal length
Newer cameras shooting at longer exposures can pick up more stars than can be seen by the naked eye. I was happy to see the Pleiades and the Andromeda Galaxy in several of my moonscape images.
ISO-320, f/4, 6 sec. exposure, 19 mm focal length
Can you spot the Pleiades star cluster in this moonscape?
ISO-640, f/4.5, 8 sec. exposure, 15 mm focal length

This was certainly a special trip spent with friends. Temperatures and sky conditions were near perfect for photographing moonscapes. I was a bit surprised we did not have more WGNSS members take advantage of this special access. I won’t complain about that too much as I think having too many photographers would have made things more challenging with fighting shadows and finding access to good compositions.

Clear skies!

Insect’s of Horn’s Prairie Grove LWR

The WGNSS Entomology and Nature Photography Groups had a splendid treat in July of 2022 when we jointly visited Horn’s Prairie Grove Land Water Reserve (LWR) near Ramsey IL. This 40 acre patch represents part of the less than 1% of the remaining southern till plain prairie ecosystem that was nearly wiped from the planet due to land conversion for farming. Even better, about 30 acres are original “virgin” prairie, (the largest intact remnant prairie in IL) meaning these spots were never touched by the plow. Even better still, at this location there lies five different types of prairie habitat: seep/wetland, dry hillside, mesic, black soil and savanna.

Keith Horn, owner and guide to Horn’s Prairie Grove LWR

The story of this land is interesting. The current owners, Keith and Patty Horn, purchased the land in 2001 as “junk land” from an old farmer who’s family had owned since the 1870s. They liked the fact that the majority of the land was in a “wild” state. The untouched 30 acres had been used as a wild hay field, being cut almost yearly. They had noticed some nice wildflowers in bloom but did not realize what they had until a few years into a wildlife habitat improvement plan that included periodic burning. Every year they noticed more and more species in bloom. They have sought help in identifying the plant species here and the current list is now at 619 species, including six native orchid species! Bravo to the Horns for identifying what they had and taking the steps to see their land improved. This remnant prairie could have been destroyed in the blink of an eye if it had fallen into the wrong hands.

Although most of us were simply thrilled to be in such high quality habitat, the primary purpose of the trip was to check out the arthropod life. Unfortunately, in late July, we were there on a truly miserable day of weather. The heat and humidity created a heat index that was well above the safety zone. This meant not many of us had the nerve to do a great deal of walking and searching, especially much after lunch time.

Autumn Photography in the Shawnee – 2022

The following images were taken during the WGNSS Nature Photography Group’s trip to Garden of the Gods (GOTG) and other locations this past April. This group is currently being led by Miguel Acosta. If you are interested in joining us for one of the group’s monthly outings, please see details at http://www.WGNSS.org!

Late autumn colors on a mirror lake.

Many thanks to the photographers we met on the trail at Bell Smith Springs Wilderness who tipped us off to a spectacular mirror lake in the Shawnee. Miguel and I stopped at this location before heading back to St. Louis. The peak fall colors were obviously passed but this place screams potential and I hope to get there again next year. We had really nice conditions for this type of photography, with cloudy skies and winds which weren’t too bad. We could have found a few more compositions but the rains came and the winds got worse so we called it a day.

A different composition from the same scene as above.

The waters here were not as calm as to be desired for our purposes, but using polarizer and neutral density filters allowed us to get long shutter speeds that helped to lessen the effects of any wind-blown ripples on the water’s surface. All images in this post from this location were taken with shutter speeds between 20 and 30 seconds.

A wind-blown mirror lake

In the photo above the wind was starting to move pretty quickly across the wider portion of the lake. Using a shutter speed of 30 seconds allows the ripples created to appear with a more painterly appearance.

Monkey face with star trails

During this weekend trip, some of us enjoyed the camping experience while others chickened out and stayed at hotels or cabins. Similarly, some of us stayed late at GOTG to do a little astrophotography. Well, I should say that I stayed late. 😉 After my friends nabbed a couple of quick Milky Way images, they headed back to their air conditioned rooms and I was left by myself to work on the photo seen above. This photo was made by combining 213 30-second images in the computer to build the star trails with the iconic “monkey face” and other rock formations that GOTG is known for in the foreground.

This was a great weekend of friends, photography, hiking and camping.

Tragidion coquus – Second Time!

For the second year in a row, a special beetle that has been described by our own Ted MacRae as “one of the rarest and most beautiful species of longhorned beetle to occur in Missouri” was found during the joint field trip of the WGNSS Entomology and Nature Photography groups at Hughes Mountain Natural Area. Tragidion coquus, purported to be spider wasp mimics, mine in dead oak branches and can be found in flight between June and November.  I wasn’t happy with my photos of last year’s specimen (also a female), so I was thrilled to be able to take the time and set her on some foliage with fall colors. It was an almost disaster as she was able to take flight before we were finished. But, having the quick reflexes of a Marvel superhero, I was able to catch her out of the air with a quick grab with just a slight kink in her antennae in consequence.

WGNSS Natural History Photo Group Field Trip – January, 2019

Bald Eagle subadult “3rd year”

The WGNSS Natural History Photo Group had a fun field trip in January, when we headed north up the Mississippi to the riverside town of Clarksville. Here at lock and dam #24, we were fortunate to be alongside ~75 eagles of various ages that took turns in catching the stunned shad that is their primary winter food source along the great river. We arrived early in the morning and made a day of it, experiencing wide shifts in weather from grey and snowy to partly sunny skies. I’m not an expert in aging these eagles, but I believe the bird picture above is a subadult II, which means it is 2.5 – 3 years old. In this photo you can see several retained juvenile secondaries on each wing.

Bald Eagle subadult “2nd year”

The long and pointed secondaries make me think this bird is probably a year younger than the bird in the previous photo. I would guess this bird is 1.5 – 2 years old. The temperatures on this day were cold, but not too severe. We arrived with the car’s thermometer reading 16°F. There was a light wind most of the day, but not nearly as bad as there could have been.

Bald Eagle Adult

With patience, there were some opportunities to capture a bird’s profile as it came to pick up a poor stunned fish.

The successful fisher

The majority of prey captured in this way is small enough to be eaten immediately on the wing in a single “bite”. Sometimes, however, the bird is forced to retreat with its groceries and eat in seclusion.

Bald Eagle subadult “4th year”

The bird pictured above is much closer to looking like an adult bird, showing the mostly white head and tail. I estimate this bird as being 3.5 to 4 years old.

Bald Eagle – juvenile fishing

I noticed this in previous years, that it seems like the juveniles spend more time fishing than the adults. In the photo above, you can see a juvenile with an already full crop is pulling another fish from the river.

This is just a few I have processed so far. We have something in the works that may produce something much more in terms of eagle photography. Until next time.

WGNSS Nature Photography Group Visits Loess Bluff NWR – November 2018

Snow drops

Seven of us made the long drive to our destination on the morning of the 23rd . The week of
Thanksgiving can be an excellent choice for visiting Loess Bluff NWR, but always depends on the
weather. We were a bit concerned with the early cold snap our region experienced this autumn.
However, in the week or so preceding the trip, the weather warmed so we were not hampered by ice
that can completely cover the shallow waters of the wetlands. Having open water affords very close
views of our photographic subjects and the primary reason we drove such a distance – the blizzard.

The blizzard

Typically, one million to two million Snow Geese will make this location a stop over during spring
and autumn migration and numbers of over 500,000 birds on a single count are not uncommon.
During our visit, the official counts were slightly over 100,000 birds, but the feeling with the group
was that this was grossly underestimated.

Rising snow

If conditions allow, getting the moon behind the Snow Geese can make a nice composition.

Rising snow against setting moon

 

Lunar Liberty

On our first day of the trip we were faced with mostly cloudy weather. As I told the group, this provides an opportunity to more easily try panning motion shots like the one pictured below. This is not my most successful attempt at such an image, but I wanted to share it here to demonstrate the multitude of opportunities for a diversity of photos to be made.

Panning with the action

Snow Geese are not the only subjects that make this trip worthwhile. The refuge also provides
important habitat for birds such as Bald Eagles, sparrows, a variety of ducks and wading birds, as
well as mammals like white-tailed deer and muskrats. On our initial entry to the park, Dave and Bill
found a Merlin on a relatively good perch above the road. We spent some time photographing the
bird, but regretted that the rest off our party were on the other side of the refuge and would not
likely be able to get the looks we did. Fortunately, a Merlin – likely the same bird, was spotted on
our second day and was viewable by all.

Merlin

With subjects in the hundreds of thousands to the millions, making a purposeful image can be challenging. It is quite natural to want to shoot at everything that moves, but try and focus. Finding smaller action scenes is one way the photographer can focus on the individuals and their stories that make up the grander scheme.

Goosing a goose

Although we experienced skies with periods of heavy overcast, we were presented with fantastic
sunsets on both days. Being able to make the birds part of the story made these images all the more special.

A beautiful end

The WGNSS Photo Group is committed to an overnight trip to this and similar locations within the Midwest on Thanksgiving week. If you’d like to join us next year, please let me know!
