Who knew the National Aviary was in PIttsburgh?? RIght up the street from the Andy Warhol Museum, no less. The aviary is small, but clean and well-organized. The tropical room and demonstrations are interesting. I watched one raptor demonstration; the keeper talked about Rachel Carson (from Pittsburgh!) and DDT. Be still, my environmentalist heart.
Odd: there is a large tombstone-type monument outside the aviary displaying the Ten Commandments. The reason for this was not readily apparent.
