@Springbok Good question. There's one bird as far as I can make out but I might be wrong. I've never seen two at once though so have said one, someone will correct me though I am sure. I don't know the origin though as you say might be timing for the juveniles from Marwell. Hopefully someone will know more.
CWP had them a few years ago so there was a history. There was a break without them. The signage for the species went back onto the Tropical House board around mid 2024.
