观察细节
At least three were along the north boundary west of the drain along with numerous sparrows and other passerines. Two were calling from Siberian Elms along the fence and a few minutes later I heard a third bird calling far overhead. All were near the cement-lined canal separating the two farthest west fields. All were identified by their distinctive call notes.
