The photo of this brown pelican (above) was taken after it landed next to the ship and began feasting on a giant ball of small sardines. If you look carefully you can actually see the sardines inside its mouth.
In the little town of Puerto Ayora the brown pelicans are almost like pets at the local fish market. In the three images above pelicans wait patiently for scraps of fish from the morning catch then get into a mad scramble with a seal over who was gong to get the best pieces. In this case the seal won.
This was more of a traditional feeding frenzy where blue footed boobies and pelicans repeatedly dove into the sardine ball for their morning meal. Note the pelican at the bottom of the image above and how full its mouth is. Some pelicans became so full of sardines that they couldn’t take off afterward and just sat around floating until they digested the fish and could get airborne.
Travel safe. Have fun.
