The Middle Kingdom Aviary - Greater Bird of Paradise (free-roaming)

Greater Bird-of-Paradise, actually

@TeaLovingDave How can you tell? Tim and I were both confused.

@snowleopard

Greater have dark brown mantle, back and lesser upperwing-coverts, whilst Lesser have the golden colour of the nape extending onto the mantle and back - also, the collection only has the one Lesser on-display, and it isn't free-flying.
