They are dangerous.
Today I saw a chihuahua walk about a group of pelicans and seagulls by the beach.
One of the pelicans just bent its head down and swallowed it up whole, and then went off after getting it down its throat, as it was chased by a distressed lady. Holding a dog leash.
Probably the most disturbing and awesome and hilarious and disturbing moment ever.
I now leave you with a video of a (different) pelican eating a pigeon....
