A Trip to Magee Marsh – Finally!

Finally, after nearly two decades of wishing to someday visit Magee Marsh, one of the most important stopover sites for migrating songbirds in North America, Dave and I made great use of some vacation time in mid-May of this year to do just that. Located along the southern shore of Lake Erie in northwestern Ohio, each spring warblers, vireos, thrushes, tanagers and other neotropical migrants pause here, preparing to cross the open waters of Lake Erie. The marsh’s forests and wetlands provide abundant food and shelter, allowing exhausted birds to replenish the energy reserves needed to continue their journeys to breeding grounds across the northern United States and Canada. Because these birds often congregate in exceptionally high numbers and at close range, Magee Marsh has become internationally renowned among birdwatchers and photographers.

Yellow Warbler

Our visit was timed nicely for being able to not only see many birds, but people as well. Our arrival coincided with the last few days of the “Biggest Week in American Birding” festival. Each day at peak hours we were joined by hundreds, if not thousands of others, trying to get great looks and photos of these magnificent birds. Typically, just the thought of being in a group of naked apes this large would cause me to run in another direction. Surprisingly, the throngs were not nearly as distasteful as I anticipated. Everyone we encountered was kind and helpful. With the flood of affordable cameras and telephoto lenses in the market the past several years, it seems most birders are now photographers as well. I think this went a long way in making everyone understand what our collective goals were and become accommodating to others. Meeting folks from all over the country and helping out one another, no matter their experience level, was a pleasure I didn’t expect.

Blackburnian Warbler

Despite forecasts that suggested otherwise, the weather and skies were mostly cooperative and we were fortunate to have many opportunities to watch tiny warblers, sometimes within arm’s reach. This was something we did not anticipate well enough. We came armed with 400-600mm prime telephotos, with minimum focusing distances in the neighborhood of 10-14 feet. During our first couple of hours hunting, we quickly realized that this was going to cause some missed opportunities. With often being surrounded by others, it was not going to be an option for us to try and backpedal to increase the distance between us and our subjects. In retrospect, bringing our 100-400mm zooms, or a 300mm prime, with considerably shorter minimum focusing distances would have been the much better choice. That’s the price we pay for not doing apt research ahead of time!

Bay-breasted Warbler

I did have a workaround that saved my bacon with the close proximity to the birds. I always carry a 25mm extension tube with my teleconverters in my long-lens bag. By adding this tube between my camera body and the lens, I was able to shave a few precious feet off of the minimum focusing distance without any loss of image quality or autofocusing speed. This meant that I lost the capability to focus on farther subjects, but those were much less frequent opportunities.

Grey Catbird

Overall, this was a memorable trip and one I would gladly do again. Let me show you the stars of the show!

Yellow Warblers were likely the most abundant warbler we encountered, showing up in every available habitat, from the marsh to the forest. We even found a couple of active nests among the buttonbush and dogwood swampy area of the boardwalk.

Chestnut-sided Warblers were damn near as abundant as the Yellow Warblers. It was such a thrill finding these guys in nearly every direction we looked!

Bay-breasted Warblers were surprisingly abundant and often travelling in groups. In the St. Louis area, these are a relatively uncommon spring find, so seeing them in such numbers was a real treat.

Blackburnian Warblers are in my top ten favorite birds. Being able to see so many at eye-level was simply thrilling.

One of my goals of this trip was to finally photograph a male Black-throated Blue Warbler. This is a more eastern bird that rarely makes an appearance in the St. Louis area. At first this goal looked unlikely. We found several females and were about to give up hope until one cooperative male was found.

The Canada Warbler was another high on my list. I did have some photos but I was eager to get better ones. We found around six of these and each was as obstinate as the last. It took a lot of time and patience to get the images seen above.

Wilson’s Warblers were scattered and singing lovely, but finding opportunities for photographs was quite tough.

Striking Magnolia Warblers were fairly common.

Of course, no good swampy habitat is complete without Prothonotary Warblers, including one that decided to build a nest in a rotten railing along the boardwalk!

Black and White Warblers doing their typical gymnastics.

I heard Blackpoll Warblers throughout our time at the marsh, but always in the treetops. We thought we wouldn’t get an opportunity for photos, but during our last hours on our last day, we found a few willing to cooperate.

It was nice watching a pair of Green Herons finishing their nest. Over the four days we spent there, two eggs were deposited.

Finally, a few miscellaneous species worth sharing.

2026 Caterpillar Season – Abbott’s Sphinx

Abbott’s Sphinx
Sphecodina abbottii (Swainson, 1821)P-no. 890192, fam. Sphingidae
Host plant: Found on wild grape (Vitus sp.)
Dates found: 27 June, 2026
Locations found: Pinewoods Lake Recreation Area, Carter County, MO
Notes: The ultimate instar presents an eerie, hyper-realistic “eyespot” complete with an iris, pupil, and even a white catchlight reflection. Along with the scale-like pattern, it becomes an apt snake mimic. If a predator comes too close, the caterpillar will lash, squeak, and try to bite its attacker. While this larval form makes a great interpretation of a snake, the diurnal adult phase makes a great bee mimic, including yellow patches on its hind wings. When at rest, the moth folds in its hind wings, leaving it perfectly camouflaged against the bark of a tree.

2026 Caterpillar Season – Distinct Quaker

Distinct Quaker
Achatia distincta (Hübner, 1813) P-no. 932800, fam. Noctuidae
Host plant: Found on Carolina buckthorn (Frangula caroliniana)
Dates found: 24 May, 2026
Locations found: Tyson Research Center, St. Louis County, MO
Notes: This common noctuid larvae can be found in April and May. This is a univoltine species, and the adults are early fliers. This species spends most of its life cycle in the cocoon.

2026 Caterpillar Season – The Betrothed

The Betrothed
Catocala innubens (Guenée, 1852) P-no. 930761, fam. Erebidae
Host plant: honey locust (Gleditsia triacanthos)
Dates found: 6 June, 2026
Locations found: Tyson Research Center, St. Louis County, MO
Notes: With more than 60 species documented in Missouri, the Catocala are common moths in our state. Despite this fact, this was my first time finding a caterpillar in this genus. Special efforts are needed to find them. They are strictly nocturnal feeders, spending the daylight hours hidden in bark crevices or even climbing all the way down their host tree’s trunk to spend the day in the leaf litter or in nearby herbaceous vegetation. Early instars can be found by beating tree limbs. Later instars can be found by searching at night. A more advanced technique involves using burlap “traps” wrapped around tree trunks. When the caterpillars move up or down, they may stay in the burlap flaps allowing you to check for them during the day. C. innubens is a specialist on honey locust.

2026 Caterpillar Season – Grote’s Sallow

Grote’s Sallow
Copivaleria grotei (Morrison, 1874) P-no. 931557, fam. Noctuidae
Host plant: green ash (Fraxinus pennsylvanica)
Dates found: 2 May, 2026
Locations found: Tyson Research Center, St. Louis County, MO
Notes: Copivaleria grotei is classified within a monotypic genus, meaning it is the sole member found in the genus Copivaleria. But it is not alone among many lepidopterans that specialize on ash trees or use ash trees as one of their preferred hosts. These species are at risk in Missouri due to the destruction of millions of ash trees by the invasive emerald ash borer (Agrilus planipennis).

2026 Caterpillar Season – Eastern Tailed-blue

Eastern tailed-blue
Cupido comyntas (Godart, 1824) P-no. 77a0638, fam. Lycaenidae
Host plant: Found on wild indigo (Baptisia sp.)
Dates found: 20 June, 2026
Locations found: Victoria Glade Conservation Area, Jefferson County, MO
Notes: A tiny, beautiful, and common butterfly that is often seen in suburban backyards, the eastern tailed-blue (ETB for short) is not a caterpillar that I have had luck in finding. Finally, on an outing with the WGNSS’ Nature Photography Group in June, I found one of these on a wild indigo plant within the glade. I never expected a lycaenid caterpillar to be such a challenging photo subject. This guy was healthy and mobile, rarely settling down to get the desired photo.

2026 Caterpillar Season – Double-toothed Prominent

Double-toothed Prominent
Nerice bidentata (Walker, 1855) P-no. 930018, fam. Notodontidae
Host plant: Found on white oak (Quercus alba)
Dates found: 24 May, 2026
Locations found: Tyson Research Center, St. Louis County, MO
Notes: A master of camouflage. The double-toothed dorsal keel and the oblique subdorsal lines matching the leaf veins do a great job in blending into the leaf on which they feed and breaking up the form of a caterpillar.

2026 Caterpillar Season – Ashen Pinion

Ashen Pinion
Lithophane antennata (Walker, 1858) P-no. 932577, fam. Noctuidae
Host plant: Found on white oak (Quercus alba)
Dates found: 2 May, 2026
Locations found: Tyson Research Center, St. Louis County, MO
Notes: This species is noteworthy for a couple of interesting natural history stories. First, this is a rare case of a lepidopteran that overwinters as an adult. Larvae of this species are also known to be cannibalistic, feeding on other caterpillars in addition to the leaves of their host plant.

2025 Caterpillar Season – Two-spotted Oak Punkie

Two-spotted Oak Punkie (Coastal Plain Meganola Moth)
Meganola phylla (Dyar, 1898) P-no. 931112, fam. Nolidae
Host plant: Feeds on any oak (Quercus spp.) within its range
Dates found: 18 September, 2025
Locations found: Council Bluff Lake, Iron County, MO
Notes: Know better as the “coastal plain meganola moth,” which is quite inappropriate. These little cuties are found as far as Missouri and into Michigan and will host on numerous oak species that are found in their range.
