观察细节
Heard at least two on the same wooded island that hosted a group back in July. Likely the same family. Saw another 500 yards away on a dead branch (bad photo). Back in July, there appeared to be one adult with two immatures, and the family would emerge prior to sunset, jump in the water edge to bathe quickly (loud splashes!), and then fly out to trees to hunt. It's possible the young are still associating with the adult here. Count could have been 3, but 2 for sure. Bad audio attached - at 1:01 seconds the group increases its pitch to sing the same five-note series - I had never heard that higher pitched song.
