观察细节
In addition to feeding young, one of the field sparrows was collecting nesting material. The first field sparrow was singing an unusual song, consisting of 4 or 5 emphatic notes followed by a long, rapid trill, similar to song in ML249845 recorded in West Virginia. Observed on the upper trail of Brookshire Park, near to summit. See attached audio.
