As I've mentioned before, I'm not the world's most patient or observant birder, but you positively can't miss these guys. They are enormous (about the size of a Great Blue Heron) and make a noise kind of like you'd imagine a pterodactyl might make. Also, they're pretty used to their human neighbours in the park, so they'll casually stroll down the path toward you. It's a little disconcerting being that close to such large pointy beaks, I'm not going to lie! I was completely intrigued by these cool-looking birds, and I immediately wanted to learn a little more about them.
