觀察細節

In flight over Frontier Rd. Flight profile caught my attention: smooth and flowing. With my bins, I observed their pale undersides, dark breast bands, and black tails. Then heard their high, soft "see-too" flight calls and managed to secure a faint recording before the birds were out of range. Attached audio file includes a half-note flight call at the two second mark (volume must be on high to hear).
