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!

Mating Harvestmen

During a WGNSS Entomology Group trip in September of last year, we were thrilled to come across a mating pair of Leiobunum vittatum (eastern harvestmen) at Caney Mountain Conservation Area. In some of the photos below, you can see the male handing off his prenuptial gift to the female. Prenuptial gifts are produced by the males and consist of a mix of essential amino acids. Mating behaviors in harvestmen are complex and vary wildly between taxa. Unfortunately, these guys were among thick scrub that made for difficult photography. I tried my best to capture some of this behavior.

First look at mating eastern harvestmen. Smaller male at back/left.
A closer look shows what I presume to be a prenuptial gift being handed off to the female at front/right.

2025 Caterpillar Season – Humped Oakworm

Humped Oakworm Moth
Symmerista sp. fam. Notodontidae
Host plant(s): Found on oak (Quercus sp.)
Date(s) and location(s): 18 September, 2025 – Council Bluff Lake, Iron County, MO; 27-September, 2025 – Caney Mountain Conservation Area, Ozark County, MO
Notes: Caterpillars of S. canicosta (red-humped oakworm) and S. albifrons (white-headed prominent) are indistinguishable as larvae and are so similar as adults that the only way to distinguish the two is by dissecting the genitalia. Both species are found in Missouri and both feed on the same host plants – beech, chestnut and oaks (any members of the Fagaceae).

WGNSS Visits Snake Road – October 2025

The Webster Groves Nature Study Society’s (WGNSS) Nature Photography Group headed to the LaRue Pine Hills in mid-October to visit the famous LaRue Rd, better known as the “Snake Road.” Our targets for the day were snakes, of course, along with any other herps that we could be fortunate enough to find. Unsurprisingly, the snake of the day was the cottonmouth (Agkistrodon piscivorus), of which we found close to 15 individuals. We found several different frog species and a real good number of cave salamanders (Eurycea lucifuga).

A short ways from the main road, we came across a small grotto. Looking closely with a light, I was able to find at least five cave salamanders resting on different shelves. After about 15 minutes on my knees, working out how to best light and photograph these guys, I finally focused my attention towards the back end of this small cave. There I noticed a medium-sized cottonmouth with its head raised that was apparently watching me the entire time, about a foot or so behind the salamanders.

Cave Salamanders and an unexpected guest. Can you find the cottonmouth?

We were joined by our friend, Stacia Novy, on this trip, who provided an unexpected treat! She brought along her two Aplomado Falcons that we had an opportunity to photograph, pet, and watch eat. Unfortunately, strong winds and a few soaring Bald Eagles that would not leave the area limited the amount of flight time the birds had, but we really appreciated the opportunity.

Afterwards, the group headed to one of my favorite breweries – Scratch in Ava Illinois. Stacia brough one of the Falcons to the outside location and we had a most unique partner to go along with our wood-fired pizzas and beer.

Grassland Bird Nesting

Back in early June of this year, the WGNSS Nature Photography Group travelled east to Pyramid State Recreation Area in Perry County, Illinois. Here we met with Stacia Novy, a wildlife biologist working with Southern Illinois University. Stacia’s goals are to find and identify grassland bird species nests, collect morphometric, embryonic and maturation data on eggs and nestlings, and to document fledging and depredation rates. Stacia is a true professional and she took care in how we approached nests and got our photographs. She finds dozens of nests each year and collects important data used for conservation and habitat management decisions.

Approximately 60% of all of North America’s grasslands have been destroyed due to agriculture and other development purposes. Unsurprisingly, grassland species in general are the most at risk birds from this loss of habitat. The numbers of these obligate grassland species have declined by 40% since 1970.

An egg buoyancy/density test is performed to determine egg age and potential viability

Due to high incidence of predation, grassland bird species must be quite careful about where and how they place their nests. Stacia showed us the types of vegetation different species like to use and how they attempt to camouflage their nests. It takes a lot of work and diligence to find these nests and we appreciated Stacia sharing some of these with us.

Here are some of the photos I took with my cellphone of some of the species we were fortunate to be able to see.
