Both adults and juveniles seen during the survey.
观察细节
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.
