Grieving Orca carries her dead baby for days

[Catherine]

The southern population of Orcas have had a hard time producing calves. One was finally born, but it soon died. The grieving mother just couldn't let it go. She kept it afloat on her head for days.

I can understand her reluctance to let the baby go. She knows it is gone and so do the other females with her. 
Now I am wondering if they were having a bit of a memorial gathering to show support for the mother and to help her say goodbye. Isn't that what out funerals and visitations are all about?

I feel for the whole southern  population of Orcas. Their numbers are declining and they have no surviving children.
