Cool weather, when the crowds leave. In cool weather temperature can't beat it. Last April 2017 I was able to check out the Denver Zoo, it's been awhile since I've been there. Wasn't impressed with new tiger exhibit, but I was able to catch the Okapi's galloping around their enclosure. They weren't just skipping about they were running! If one listened you could clearing hear their hoofs. IT WAS TOTALLY AWESOME!!! It got better when I stopped by the Malayan Tapir. He was walking around the enclosure, then eventually he picked up his large food dish with his mouth and carried it to the door where he comes into the exhibit. Upon further observing him move about the enclosure he started to vocalize. Shortly there after he would start running around the exhibit. In the course of his travels around the enclosure he would jump into the air! It was SPECTACULAR!! Next to the tapir was a large indian rhino exhibt. At the same time this rhino would start galloping around their enclosure too! It was totally unbelievable. Watching this enormous rhino running around their enclosure several times. My heart was in heaven. One of my best zoo visits! Several years ago I was walking through Forest Park St. Louis heading to the zoo, and it's raining. It starts really mid-western RAINING! Like coming down in buckets, which thunder. As I reach the zoo, I immediately head to the reptile building. In short order of time I realize I'm the only soul in the building, I'm sure there were staff behind the scenes. Anyway I discover many of the snakes are moving about their enclosures! How many times we go to the zoo and the snakes are just so to still, not this time! Many of the snakes were as active as possible hungry maybe. In course of time when a keeper came around he mentioned the atmosphere events outside were influencing the active of the reptiles in the building. IT WAS SO AWESOME!!! The king cobra readily roaming throughout it's entire enclosure.
When crowds go home...this is usually toward the late afternoon going toward closing hours. The zebras, and wild horse come out closer to feeding on the grasses, the big cats start showing signs they are very much alive. It's sweet!
Just the other day was at the Seattle Zoo, and was able to watch the Emerald Tree Boa move through it's large exhibit. How many times we see them o so still. This one was stretched out so long. The Cock-of-the-rocks were perching close to being readily photographed, and toward the closing time were starting to vocalize. That sound was so COOL!
