Because it would be like, a wise choice (owls = wisdom) to have health coverage.
The wisdom to see all aspects of health related issues and how to heal them.
Owls represent wisdom (which for me, ties into protection)
As opposed to the other options and they are supposed to be smart
Eagles seemed like a good fit. They soar high. They nuture their younger ones. They've got leadership traits.
Dolphins have been used to save lives during the cold war and I think about their life saving capabilities.
well eagles are the symbol of protection and represent America. Health is key to pinpointing the reason or patient is sick, xrays, eagle vision, to me is a good representation.
