Guira Cuckoo

It's always lovely when I see a new bird at Birdland and today there were 4 of these cuckoos in a cage together. They are South American birds and apparently nest communally with several pairs building the nest together and then sharing the care of the young. A little different from the UK cuckoos!!
In extras I think these flamingos might have been mating but if they were the lady kept eating the grass throughout the short session.
