觀察細節
Minimum count, by twos. This species seen during most or all of the count. Heard frequent, rough vocalizations that reminded me of EUST - perhaps juvenile calls? 4 juveniles (bare minimum) confirmed from photos. At or before 0600, a group of at least 25 swallows, apparently mostly CLSW with a few BARS, flew over from the east. CLSW seen frequently in the air; I also saw groups perching in a row of Prunus virginiana substantially south of the stream in reach 3.
