"What a thousand acres of Silphiums looked like when they tickled the bellies of the buffalo is a question never again to be answered, and perhaps not even asked." -Aldo Leopold
This series was taken on the joint outing of the WGNSS Entomology and Nature Photography Groups at Council Bluff Lake. Here we have eastern black carpenter ants (Camponotus pennsylvanicus) feeding on a freshly dead ring-necked snake (Diadophis punctatus).
Along with finding the typical rarities that everyone looks for during spring migration, I will not count spring as arriving until I lay eyes on a male Blackburnian Warbler. This past Saturday, not only did Miguel and I find my prize at Carondelet Park, but I got my best photos to date of this tree-top dwelling, piece of greased lighting.
With a throat this bright and luminous, a song that is so high-pitch that dogs aren’t safe for blocks and a never resting habit, more than one birder has assumed these guys must be powered by a battery. Seriously, there’s a reason these guys eat all day long. They have to!
Well, hopefully I might have another before the season has completed springing. If not, I’ll always have something to look forward to next year.

Miguel Acosta and I decided, along with many other birders and bird photographers, to head to Tower Grove Park to check out the latest migrant action. Although the migrant songbirds were overall pretty disappointing, the morning was surely not a bust for me as I was able to photograph my 282nd species in Missouri and contiguous states – the Veery.
This guy’s polyphonic vocalizations have been among my favorite of bird songs for a long time. On the rare occasion these guys sound off during migration, the songs come from a deep thicket and I rarely get to lay eyes on the songster. The beauty of migrant traps like Tower Grove and Carondelet Park in the heart of the city is being able to get great looks at these northern nesters.

With some extra nature time last week, I hit the trails at Shaw Nature Reserve hoping to get some shots of Claytonia virginica (spring beauty) being visited by its pollinators – particularly the small solitary Halactid bees. The problem I had on this day is that these bees don’t typically like to be very active on cloudy, grey days. There were a few flies visiting the spring ephemerals, but they were much to flighty to bother with. So, I decided to give some attention to the Lindera benzoin (spicebush) that were blooming in abundance along the river bottom trails. My goal then became to document the pollinators that visit this early-blooming bush.
One of the more obvious of these pollinators that I found was this sawfly. This is my best guess on identification. This sawfly was quite small and by the looks of it, is quite an efficient pollinator.
Probably the most abundant pollinator I came across were these Tachinid flies (again, flies are difficult and I could be wrong).
The hair-like setae that probably serve to aid the fly in responding to changing air pressures also serve as nice holders to move pollen from flower to flower.
I also found a number of multicolored asian lady beetles (Harmonia axyridis). Typically predators of aphids, these beetles are also known to feed on pollen. This is what I figure was going on in the image below. Since there are probably few aphids to be found during the early spring, with few leaves being available, pollen is the next best protein source. I suppose there could be aphids to be found hiding within the flowers, but did not inspect closely enough.
Probably my favorite find of the day were several flies of the family Empididae. These are fascinating flies that are primarily predatory, but a few taxa will visit flowers to feed on nectar or pollen.
Within this family are at least a few where the females will not hunt themselves, instead relying on a “nuptial gift” of a prey item from a male. Males of some species will wrap their gift in a silk wrapper. In these taxa the sex roles will often be reversed – the females courting the males to get these gifts and the opportunity to mate. In at least one species, the females will inflate themselves grossly with air to give herself the appearance of being bound with eggs and fecund, to trick the male into thinking she is a prime candidate to provide his gift and have the opportunity to mate with.
At least one species has taken this system a step further. The males no longer provide a prey wrapped in its decorative covering, but simply provide the silken covering, or balloon, giving them the name “balloon flies”. The photo below provides a good look at the dagger-like moth parts that give these guys another of their common names. Another overlooked beneficial fly. Not only do these guys prey on mosquitoes and other potential pest insect species, but their larvae are also predatory, feeding on insects in the soil and leaf litter.
I’ll leave you with one final image. This one isn’t a pollinator of the spicebush, but potentially feeds on its leaves in summer. What I believe this to be is a (Camptonotus carolinensis) Carolina leaf roller that was parasitized by one of the “zombie fungi”, potentially Cordyceps sometime last summer or early fall. This poor cricket was infected with this fungi that took control of its “mind”, forcing it it to climb high up on a branch of the spicebush. Once there, the fungi used the cricket’s resources to fruit and spread its spores from this higher location in order to reinfect others.
Until next time…

For the first time since junior high I did not watch a single down or minute of the NFL this season and I couldn’t be happier for it. Rape my town three times, NFL – shame on you. I’ve been pleased to get those precious free minutes back for my Sundays, several of which I found I could spend not dreading the upcoming workweek.
When the forecast showed a near perfect meteorological condition for shooting the Short-eared Owls of BK Leach, I figured this could be promising. While most other naked apes with functioning vision would be in front of the picture box and ingesting mass quantities of wings and beer, I would enjoy the warm and lightly breezy evening in my own kind of chair with friends of a different sort.
Of course there is never a sure thing. Often, when I have expected the best due to light and temperature, the owls don’t show where I set myself. On this particular day, all conditions came together and I had a super time.
I want to give huge thanks for my lovely and talented wife, Sarah, for the special help she gave me this season in getting my best to date SEOW in flight shots.
A perfect day ended in the perfect way – with a great sunset on the Lincoln Hills.
Until next time…

This gorgeous redhead is the White-marked Tussock Moth (Lymantriidae – Orgyia leucostigma – 8316). I was amazed at how abundant they were and routinely found on the underside of leaves on woody plants this summer. Most folks have never seen one!
Besides their striking colors and patterns, these moths have toxin-filled hairs that can cause irritation, especially to areas of sensitive skin. I have not yet photographed an adult, but I was interested to hear that the females of this species are nearly wingless and cannot fly.
Until next time…

When traveling to a new location it is always interesting to see what gull species is the local equivalent to our Ring-billed Gull. In the case of the Texas gulf coast, that is definitely the Laughing Gull. We found that a really great place to see hundreds at great distance is the ferry ride between the Bolivar Peninsula and Galveston. Be sure to check the water as well as the skies if you take this 20 minute boat ride. Steve and I were able to spot a bottlenose dolphin or two during the crossing.
After hearing their vocalizations for quite a long period, we can say this species is quite aptly named!
In summer plumage, this is obviously one of the easier gulls to identify. Largest of the hooded gulls, with red bill, legs and feet, slate-colored back and black primaries.
Most birders who have had the opportunity to travel will know about High Island, a small township along the gulf coast that is among the most famous of birding locations in the country. This relatively small plot of land, along with other spots within a few minutes drive, can boast bird lists higher than many states, if not whole geographic regions of the country. What surprised me during our visit last May was the diversity in habitat. High Island is mostly famous for its potential for massive fallout during spring migration – migrating songbirds either traveling up the coast or flying directly over the gulf will stop here for a drink of fresh water and to fill up on grub before continuing north to nesting grounds. We realized we were going to miss most of the migration at the end of May, but still wanted to pay a visit. The place is so popular that there is bleacher seating around key ponds to allow for visitors to watch as birds by the hundreds land for a drink and forage through the live oaks.
The numbers and diversity of songbirds across the Houston/Galveston coastal areas we visited were even sparser than we anticipated, but on arriving pre-dawn at the rookery we were quite surprised. Every bit of vegetation on this relatively small island was being used by wading birds. We were in awe by the numbers of Neotropical Cormorants and Roseate Spoonbills that filled the branches as well as the skies.
Lighting was quite challenging – what little light available at this time of the morning was often coming from behind the subject. Evening may have been better photographically but we had lots of ground to cover. One of the sights that had me the most excited was a nesting Great-Egret. These are birds that are routinely found during the warmer months in Missouri, but finding one feeding chicks was a real treat.
Early in the dawn hours we were treated a Common Gallinule (Moorhead) hen bringing her chicks down to the water for a drink.
Prehistoric looking Spoonbills would sometimes fly right overhead.
I hope to visit High Island some spring during a nice fallout period one day, but I will be just as excited to watch and photograph at the rookery once more.
You can see more photos from the High Island rookery and the Texas Gulf Coast by visiting me on Flickr.

It was a pleasant surprise to be able to add two new owl species to my bird species photographed list over my long holiday break. The second owl species and subject of this specific post is the Northern Saw-whet Owl. Although this species can be found in the Show-me State during winter, I heard of a location along with a Radagast like wizard who could conjure up this species upon request within a mere eight-hour drive from our front door. Having waited longer to do this than we should have, Sarah and I loaded up the Subaru and headed for the wilds of west-central Iowa.
Don Poggensee is no mere wizard, but an accomplished photographer, pilot and naturalist who loves spending time during his retirement monitoring the park’s owls and showing them to anyone interested in getting exceptional looks and knowledge about these visitors from the north. Don has been monitoring, helping in banding projects and showing folks (in the hundreds, if not thousands by now) the owls since 1989. Sarah and I met up with Don one morning along with a couple of other birders, including The Birding Project’s Christian Hagenlocher. We grabbed our cameras and binoculars – not that we would be needing these and followed Don to the specific roost tree that he knew the owl would be found.
Winter weather in this part of the Midwest can be brutal and unpredictable. In the days preceding our visit, temps bottomed out at ~ -25 F. As Don explained to us, colder temperatures and heavy snowfalls often force the owls to find more suitable roost sites that he is typically not able to find. We lucked out and had rather comfortable conditions for the short hike to the owl’s roost tree.
Saw-whets are year-round residents across southern Canada and the northern U.S. but winters across most of the continental U.S. They typically can be found roosting 3 – 12′ in conifers but can also be found in honeysuckle tangles in winter locations where their preferred conifers may not be abundant. Banding programs, made up of mostly citizen scientists have only recently begun to shed light on the seasonal migratory movements of this species. Along with locations and dates, these banding programs have shown that most migrants are females or immature males. Adult males stay on breeding grounds during winter, presumably to hold onto prey-rich territories.
In case you are wondering, Saw-whets got their name from the apparent similarities that one of their common vocalizations has to the sounds made by the sharpening, or whetting of a saw’s blade. They actually make at least nine distinct vocalizations, including an ascending wail that is reminiscent of an Eastern Screech Owl.
At six to nine inches high, our typical response is to wish to put one in our pocket to take home. They are quite cute. However, to nearly anything that is their size or smaller, these guys must be regarded as horrifying. While checking roost trees we found a number of their tiny pellets, each with surfaces studded by the stained bones of their rodent prey.
