The Montgomery Zoo, in Montgomery, Alabama, is not AZA accredited. Perhaps you were thinking of that facility? To answer your question, the male they have received is two and a half years old, so a young male, yes, but definitely old enough to breed. The bongo SSP is quite a mess at the moment, and there are a lot of animals needing placement and whose moves are in limbo, and facilities are always looking for holders for surplus males. I won't claim to know what their plans are for him, but it could really go either way.
