觀察細節
Mostly 2’s, some typewriter-like, klippy flight calls from within one group, sounding okay for type 4. Tried for some recordings with iPhone, but most poor — will see how sonograms turn out. Many groups floating around the area. Close estimate, erring on the conservative side. One group of at least 18, counted in flight. Several other groups circuiting the area.
