I saw the numbers being hand written by a keeper. The sunlight coming therough the tropical foliage caused all the shadows. Some of the birds were easy to see, but I think you would be lucky to see the rose-breasted grosbeak or a rainbow bunting. There were some guira cuckoos in the outdoor aviary beside the entrance with the hyacinthine macaws.
@gentle lemur I have feeling a good number of the birds they have now were recently obtained… if they were there when I visited I may have enjoyed the visit more!
