Long-tailed Duck pursued by coots and Redhead Ducks

I don't know what it was about this female Long-tailed Duck but first the American Coots chased her away then 2 Redhead Ducks did the same. After she swam close to the cliffs she tucked her head, closed here eyes and appeared to rest (though even with the shelter of these cliffs her feet were always moving to keep her in place). After awhile several American Coots swam close in. She opened her eyes to watch them. As they swam at her she untucked her head and swam away. This happened several times and the top pic shows one of the coots as it was pursuing her. Then after she came back in and was resting again two Redheads started swimming after her as shown in the bottom pic. After she swam distant from the other ducks, they let her be. Finally I watched her come back in close to the shelter of the cliffs for a third time and this time she did not let the other ducks intimidate her. She appeared to vocalize as shown in a pic on the previous post which may have communicated that they should let her be?? SeEtta
