What about the sea lion, black bear, and Cougar? Also, your last two are the same animal. Congrats to the bison! Definitely an excellent fit for the role and some the WCS has been working on getting done for quite some time now. ~Thylo
I juts wanted to present some typical American native mammals that would make also good choice, appart from the (American) bison.
The American bison, though, has a unique history in this country.... from its keystone status in the prairie ecosystem, its earlier abundance, its near extinction due to the whims of commercialization, and its survival and success due to the collaborative efforts of several NGO and governmental groups. No other native animal shares such a legacy. Really a fine choice. It sums up this nation's relationship with wildlife, from exploitation to promise.
I agree. Those other animals are great, but none of them have the history or cultural significance of the bison. (another thing to add to your list, bison were and still are important to so many Native American cultures)
