I suspected as much, and I'm glad you've confirmed queerness (aka gay animal behavior) in other animal species (other than human).
I recently dusted off drafts of the science-fiction novels of a series and have been publishing them in ILLUMINATED -Curated. One of the humanoid species with tens of thousands of years life span change gender around the time of conception, communicate with the unborn spirit of the child to make a more harmonious life.
An addendum/side-story in world building for the Antarians - I include a piece on their procreation rituals.
Thanks again for the summary of the research.
