Very cool part of their collection! I haven't seen a Green Broadbill in a U.S. Zoo in nearly 30 years! This is a beautiful species that I would love to see become established in the U.S., but it seems unlikely based on past experience. I believe that only Riverbanks and Chicago Lincoln Park are the only U.S. zoos to exhibit this species. My recollection is that this species builds a very intricate suspended nest similar to that of an oropendola.
