Prothonotary Warbler surveying his options, left, right, left. Warblers are speedy, often chasing lunch; this one took a few pauses sort of in the open.

This Prothonotary Warbler’s nest is in that cavity, and the parent spent several minutes poking his head in, like he was moving something around.
I did not see if he brought something on this trip to the nest, like he did when I spotted the parent two days before: Prothonotary Warbler Bringing Food Home
The hole is about my eye level and I did see one chick beak when I passed by.
The parent did fly off with a fecal sac, something I hadn’t seen up close before.
Sitting just off the trail this Prothonotary Warbler was perched, but not singing, which is a common behavior. I didn’t notice at first that his beak was stuffed with lunch.
Not for himself, but he was taking this meal to his nest.
He quickly stuck his head in…
then flew off for another serving.
I didn’t hear any chicks so suspect he was feeding his brooding mate.
I returned to Beidler Forrest one morning this week hoping for another opportunity to see a Prothonotary Warbler or two. I did hear a few high in the tree tops but mostly they eluded me. The promised sun did not materialize, keeping the forest dark.
I did capture this one as it was returning to its nest, which the center staff pointed me to. The nest is down inside that Cypress knee. After a moment the adult dropped into the nest and stayed put for at least the next twenty minutes, likely laying on eggs.

The Prothonotary Warblers have returned to my area. Often you hear them before seeing them, even with this brilliant yellow.
These images were taken at Beidler Forest which has many of the features these warblers like: tree cavities for nesting, damp forest floor, dense undergrowth and both standing and slow moving water.
As I was leaving for the day one final Prothonotary Warbler crossed my path and perched on an open, if dimly lit, branch for a few moments.
The light was low and it was raining off and on as we made our way around the board walk over the swamp at Beidler Forest, a property managed by Audubon South Carolina. I heard a warbler calling way before I saw this bird and his mouthful of bugs.
I was quite surprised he was so close to the boardwalk. He moved to different branches a few times, keeping a tight grip on his bug collection. After a couple minutes he flew out of my sight.
Further on I spotted another Prothonotary Warbler bringing food to a nest in a Cypress Knee. It was even darker then and rain was about to fall in earnest. The image is not great but you can get an idea of where these warblers rear their young.
Both of these birds were banded, part of a research project to study their migration.
Beidler is the world’s largest virgin cypress-tupelo swamp forest — a pristine ecosystem untouched for millennia.
