Other Activity: perched on nest platform, sitting on marsh,
Observation Method: visual from house
General Comments: This pair seems now to be well connected to this next site. Likely the returning pair, especially the female. In past days, high winds, rainy times, etc. have seemed to lead to birds staying away from nest for long periods. Female has been present much more than male. She has done some effort at nest building, but winds have regularly pushed sticks off platform. Female has also seemed more defense of nest site than male. Previous pair had one banded bird, presumably the male. At times an unbanded male has been present.
