I read once long ago that of all large game in N. America, the black bear “gives up the ghost” the quickest. This has been my experience as well.
Walk
Both of the black bears that I've shot died very close to where they were shot. One bawled a bit first but didn't run far.
Moose seem pretty much the same. The three that I witnessed just ran a few steps and stood until they fell over dead.
