Observation details
The audio had been run through the Cornell Birdnet audio app. The app suggested PABU as the probable species. Mark, thanks. My original ID was YRWA, Myrtle's: A slightly late in migrating YRWA, identified by my spring song, attached. Quoting from Dunn/Garrett’s Peterson Field Guides, Warblers, 1997, page 269, for the Voice of both the “Audubon’s” and “Myrtle Groups”: “…songs are often given on winter grounds in early spring (these spring songs are often less structured, quieter than territorial songs on breeding grounds.” Specifically for the “Myrtle Group”: “Song is variable and rather loosely structured trill, often difficult to identify.” I used the sonogram of the attached called and spent hours trying to match the sonogram per eBird and the sonograms per xeno-canto. [A Bird Call/Song Rosetta Stone would be helpful to compare the latter two sources, the xeno-canto sonograms, as presented are smaller in length, time-wise, and taller in height on the vertical frequency scale.] The frequency range and length of the recording can be determined to be consistent between my recording’s sonogram and xeno’s examples. The sounds and cadence between my recording and xeno’s are close. I did not see the bird, but it was less than 100 feet away in heavy tree cover alongside a dirt path paralleling the River Trail. Relevant references in xeno-canto for Myrtle Warbler are: XC551319, XC328187 and XC31665. All three of xeno’s examples are between April 27th and May 5th.
