The males sing intermittently, and the pairs could be spotted in this fashion. One pair was collected and prepared for skeletons (708-709). Another pair showed considerable alarm when I approached it. The alarm note is a sharp tzep or tzip. I soon became aware of a soft, repeatedly given tree-tree-tree coming from a dense thicket.
