Yes it was a bummer, but being my 4th time at the zoo i've been plenty fortunate to be graced by his presence on prior visits!
It’s anticipated Melbourne will receive new females (likely two) within the next year, so during the settling in phase, there may even be closures to Melbourne’s exhibit. Long term, it’ll lead to a healthier troop structure, so will be a good move in the long run.
Melbourne’s exhibit is fantastic (especially considering it opened in 1990). I liked the multiple view points.
