NOTES: (Altitude: 0-65 m. No. of Animals/Sex: male(s), female(s).) One bird was singing high up = male!? The ssecond was giving the "ratchet" call below near thenest = female?? However both "ratchet" and I was focusing on whichever was calling, trying to get a wide a range as possible of their calls. Included at end of cut are "roll ratchers" uttered near nest. Song contginues as male comes in and out to nest in which there were young! wing "ripping" heard.
