The funny thing is that I knew exactly what they were as soon as I saw them. I guess there's no mistaking what a pelican looks like. Of course I had to check later just to make sure, but my guide confirmed that they were indeed pelicans.
I probably could have gotten a little bit closer, but I was afraid they would leave if they saw me lurking around. Maybe I would have gotten a few good pictures of them in flight, but I didn't want to risk it. And besides, it wouldn't have been nice to disturb them. I'll talk to you later.
