Подробности наблюдения
Heard only except for brief, distant overhead views that could not be used to ID the birds. It sounded like 20-ish birds were flying in loops overhead as if they were moving between roosts but only 5 were actually seen. Occasionally a single, more distinct bird would call using the slow chip, chip, chip voice, rather than the rapid fire trills.
