Pelicans.

I occasionally do transports for the local seabird rescue. This usually involves driving down the coast and picking up the birds from animal shelters, coast guards, and other agencies. Most of the time somebody else has already picked up the birds and driven them part of the way. When I've got several birds to transport at once I like to say I have a car full of pelicans, because it conjures up this sort of image:

The truth is that the birds are always transported in cardboard boxes; the dark makes them feel safe and secure, and they can't accidentally poke out anybody's eyes. So far I've transported pelicans, cormorants, and a grebe. Even in boxes, seabirds make my car smell like fish.
