Heard only, in the thick vegetation by the sidewalk, between the bathrooms and the beach. The bird moved towards the point low in the vegetation, never giving a good look. It either flew north along the shore or across the lake. It gave constant but irregular chit calls (see attached audio.) Excluding Carolina Wren because their call is a clean sounding, almost whistle like chirp. Excluding House Wren because their call is a more rapid series of notes that have a bit more of a crisp pop to them. Excluding Winter Wren which has a bit more of a squeak to it and is nearly always a series of paired calls. Not burry enough for a Sedge Wren call, which also typically issue a paired set of calls. Merlin was unable to identify in situ despite really good samples, which tells me it was not an expected bird for this date/location. BirdNET identifies it as Marsh Wren with an 89% confidence. There are a number of September records for Marsh Wren in the Triangle but this bird would be a week earlier than previous records. More likely a bird displaced by TS Debby than an early migrant. The 'voice' and cadence of the calls sound really close to ML209378861 and ML622786846.
