@cuckooduck There was one pair on display but I noticed another individual in the off-view breeding section when (fortunately) they opened the area for public viewing. Unfortunately I was only able to see the horned screamers from a distance as we were not permitted to go that far into the section although there was a sign telling visitors to look over there. It was wonderful to see these amazing birds and they were very steady, happily going about their business close to the front of the enclosure.
