Then makes 1 pr. movement. Then starts to utter TssN's in same posture, with wings less drooped.

Then flies to another station 7:20. Utters TssN's. Usual posture. No Back R or Wing droop. Head with general erection of feathers (but not very extreme).

General erection of head feathers may be sexual???

These birds have uttered many fewer NN's during the last few days than when I first started to observe them. An indication that they are getting used to me.

All quiet now 7:25 a.m.

Male back 7:40. On station, uttering occasional Ф's. Low intensity.

Gone again almost immediately.
