Randomly searching, I saw Buttonwood Park Zoo (MA, USA) were supposed to have a black skimmer, Rynchops niger based on ISIS data from May 2011. I hadn't heard about the zoo before and would be interested in details. Are there any other attempts of keeping a skimmer species in captivity? Beyond briefly in wildlife rehabilitation centers where I guess force feeding can be used (obviously not possible if trying to keep it long-term). I'm especially interested in knowing if natural feeding has been achieved by anyone -- it would probably require a huge aviary with a very large water section?
