I've mentioned in other threads that I'm used to thinking of eastern black rhinoceros as the most common rhinoceros species as almost every US zoo I've visited is either a recent or current holder for these (Lincoln Park, Brookfield, Milwaukee, Denver, Saint Louis, Racine) -- meanwhile I've only seen Indian rhinoceros once and I've not actually seen White rhinoceros to date, even though those are fairly numerous species as well and the latter definitely outnumbers holders for black rhinoceros.by a noticeable margin!
In regards to the elephants at hand, I've been to three zoos that hold Asian elephants (Saint Louis, Denver, National) and three that hold or recently held African elephants (Milwaukee, Brookfield, Lincoln Park) and two complete non-holders (Racine, Henson Robinson) so far... during my upcoming trips, I'm expecting to see African at least once more and Asian at least once or twice more though, so it's staying relatively even.
