Description of Habitat

a typical Vermont 'wet meadow' with areas of higher, drier spots and depressions of sedges and reed canary grass, scattered with short shrubs

Behaviors Observed

One Sedge Wren flew to a clump of grass repeatedly (at least eight times) with food in its mouth during our visit although we did not see this behavior until the last 45 minutes or so while there. Each time the bird came back out with nothing in its beak. It would frequently disappear into the grass nearby and pop up a few seconds to minutes later with food it its mouth (at one point we could see an insect with large wings) and fly low over the grass to the nest site. As this occurred the second bird, presumably the male, sang from a low perch 10' to 30' away.

Description of Vocalizations

dry rattling song with two-three introductory notes; raspy call notes

Verbal Narrative & Description of Observation

A Sedge Wren was first discovered by Kyle Bardwell at this site on May 28, 2022. On May 29, 2022, two Sedge Wrens were reported by Jo Jo Doyle, Jim Mead, Craig Provost, Linda Shelvey and Brent Stephenson. On June 1, 2022 John Peckham reported two Sedge Wrens that appeared to be copulating. A Sedge Wren was photographed and recorded many times by multiple observers since the original report.

We arrived at the site at mid-day on June 27, 2022 after a morning of heavy rain. As we first entered the meadow from the woods, a Sedge Wren was singing in the immediate area. It proceeded to sing from several perches in the area no further than 30'-50' from where we stood. A couple times a second Sedge Wren could be heard calling from a different spot, but in the same immediate area. For the last 45 minutes or so of our visit we noticed the second bird fly to a low, tan clump of woven grasses set within green grass (maybe Reed Canary Grass) not far from the trail (see photo) and near some shrubs. The nest was probably about one foot from the ground and well hidden. We did not want to go further to inspect.

I understand male Sedge Wrens build dummy nests, but it was into this clump that the presumed female flew with a mouth full of food and then re-appeared with an empty beak. This was repeated at least eight times while we were there. The bird would fly out and disappear into the grass nearby to re-emerge with another mouthful of food. All of its flights were just above the height of the grass while the singing bird would take higher flights.

I did not include a photo of the nest or breeding codes in my eBird checklist for the protection of the birds.

Relative Size & Shape

A small bird with a typical wren profile of a short, upturned tail.

Head

Crown with fine streaks darker than face; cheeks tan and relatively unmarked; eye appeared dark with a bit of a pale eyebrow; throat pale and unmarked nape brown.

Feet & Bill

Feet tan/dull pink; short bill, slightly decurved, pale in color.

Upper Back

Upper bill black and white streaks.

Lower Back & Rump

Could not see as wings were folded above.

Wings

Wings medium brown and darker brown.

Breast, Belly, Flanks, Under Tail Coverts

Upper breast cream becoming tanner on lower belly and flanks.

Tail

Tail upturned and barred.

IMPORTANT: What similar species were eliminated when making the identification and how was this bird different?

House Wren has less distinct markings and appears a more uniform brown all over. Marsh Wren back has finer black and white streaks on back and overall a more warm brown appearance. Carolina Wren too big; Winter Wren too small.

Other Notes & Comments

Both birds were identical and appeared to be adults. Presuming only the male sings, there were a male and female present.
