I was parked along the auto tour road at Sequoyah National Wildlife Refuge, focused on a Barred Owl sitting in the timber nearby. Then a Prothonotary Warbler dropped in and landed close to my pickup. I pivoted, got my camera on it, and grabbed a few quick shots before it moved on.

Prothonotary Warbler: What to Look For
The Prothonotary Warbler is hard to miss. The male is covered in rich golden-yellow, which is brightest on the head and chest. The wings and back are blue-gray, and the contrast between those two colors is striking in good light. It is one of the only warblers that nests in tree cavities, which sets it apart from most of its relatives.
Habitat at Sequoyah
These birds are wetland specialists. They nest and forage in flooded bottomland hardwoods and swamp forest, exactly the kind of habitat Sequoyah has in its lower sections near the Arkansas and Canadian rivers. The four-corner intersection on the auto tour road sits in prime territory for them. Flooded timber, standing water, and dense undergrowth give the birds everything they need.
Timing and Behavior
Prothonotary Warblers are neotropical migrants. They arrive in the southern United States in spring, typically from April into May, and breed here through summer before heading back south. May 7 puts this sighting right at the peak of spring arrival and early breeding activity. Males are vocal and active during this period, which is likely why this one was moving around in the open near the road.
They forage low, often at or below eye level, picking insects and small invertebrates from bark, branches, and the waterline. This one landed close to my truck, which is not unusual. Birds in refuges with regular vehicle traffic can be less wary of a parked vehicle than a person standing in the open.
Photography Notes: Capturing a Fast-Moving Warbler
Gear and Settings
I was using a Fujifilm X-T3 body with a Canon EF 100-400mm lens connected through a Fringer EF-FX Pro adapter. The camera was resting on a bean bag over the open window of my pickup. That setup keeps everything steady without a tripod and lets me pivot quickly when something unexpected shows up.
The settings were f/7.1, 1/1600 sec, ISO 3200. I applied -0.33 exposure compensation to pull back a little and protect the detail in those bright yellow feathers.
Why Those Settings Made Sense
Early morning light at Sequoyah can be soft and low, which is great for color but tough for exposure. ISO 3200 on the X-T3 handles reasonably well in those conditions, and 1/1600 was fast enough to freeze any movement from the bird or any camera wobble from the bean bag. The f/7.1 aperture gave me a little more depth of field than a wide-open setting, which helps when a small bird is perched at an angle and you want the head and body both sharp.
The exposure compensation call was the right one. Bright yellow feathers in even moderate light can blow out fast if you trust the meter alone.
Vantage Point and the Vehicle Blind
Staying in the pickup is one of the best moves you can make at Sequoyah. The vehicle acts as a blind. Birds that would flush if you stepped out will often ignore a parked truck entirely. This warbler landed within comfortable range and held still long enough for a clean shot. If I had been on foot, I doubt it would have come that close.
A Good Reminder About Staying Ready
I was set up for an owl when the warbler appeared. That happens a lot at Sequoyah. You go out for one thing and something else entirely walks into frame. The only way to make the most of those moments is to keep the camera ready and the settings dialed in for the conditions you are actually in, not the ideal conditions you wish you had. This shot worked because the camera was already live and the exposure was already close. The warbler did not give me time to adjust much.
Sequoyah keeps producing moments like this one. It is one of the reasons I keep going back.
