Birds Do It...Bees Do It

I snapped this pic in my garden. It's a migrant!
Let’s consider the word MIGRANT.
"Migrant" connotes species moving, temporarily, for a particular reason, with the intention of returning to its origins.
There are, most notably, migrant workers. There are far greater numbers of migrants in other species, however. Consider: birds, butterflies, bees, diseases, fish, to name a few.
When we usually think of the word migrant “people” come to mind, those that relocate, for instance, for work, habitat, or safety. This is different from the word IMMIGRANT, in that an immigrant does not expect to return to its origins, it is relocating permanently.
I propose for this iteration of V9-4 the word MIGRANT
