Apr 8, 2017. The Pelican Beakon, the pelican newspaper, covered #PelicanYoga's advanced dusk diving classes at the Sunshine Skyway Bridge. This was as exciting as it was dangerous. Up high, there is some light to see, but as pelicans dive, the water gets darker. The class is popular before nesting season. The parents need to feed more in order to have more food to regurgitate and maintain energy.
