Northern Passage - North American porcupine exhibit is complete. Lots of ample climbing spaces and a decent addition to the original Common raven exhibit. Oscar is still in Wading Bird outdoor holding at the moment, so he should be on exhibit shortly. Other exhibit updates include additional exhibit graphics, information boards, and a simulated bear den.
Main Valley - Crane Barn is almost finished. Currently the building is being painted. I'll update the media gallery when the renovation is complete. A few of the old Victorian cages have been removed.
Overall, lots of minor cosmetic changes and a sprucing up the campus after the Zoo and nearby National Aquarium co-hosted the AZA Annual Conference earlier in the month. The Zoo also has started advertising their newly released master plan. Banners highlighting proposed changes have been installed and based on what I overheard, many guests are quite excited for the changes.
