Media notes
The notes indicated at seconds 1.5, 2.0 and 2.5, below the tightly-spaced marks in a straight line in the middle of the sonogram, seem the most likely to be Tree Swallow notes.
Observation details
All the audio clips were taken from videos of Tree Swallows, often with bill moving, seemingly indicating vocalizations. Other bird vocalizations were captured at the same time, however, and it is difficult to separate one from another. I did not detect the liquid notes for which the Tree Swallow is known. ML101198971 seems to have the vertical lines, squiggly marks, and descending squiggly marks which I noted in the sonograms below.
