Brown Pelican

Brown Pelicans are common around Rockport, Texas. Their aerial dives into the water are entertaining. Laughing Gulls, hoping the steal or scavange the pelican’s catch, often accompany the pelicans.

The photo below really should be credited to both of us. Erika found a pelican sleeping on a pier. The bill is completely hidden in the back feathers. “Take a photo, Dan,” Erika said, “that is certainly a Kodak moment!” Notice the half-open eye. Birds (and some aquatic mammals) are able to sleep with one eye open and half of their brains awake. The ability, termed “unihemispheric sleep” allows them to sleep, while, at the same time, be alert for predators (Mascetti and Vallortigara 2001).
