观察细节
We heard the group is at flew in and perched atop cypress trees. Bob and I rushed over and got recordings and good looks before a flock of EUST flew through, and the whole group of RECR alighted out over the ocean, circling briefly and departing south. Calls indicate type 3, with noticeable letter “n” shape in the spectrogram. Sweet!
