Nutrition utilization by and diet preference of American white pelicans (Pelecanus erythrorhynchos) when offered diets of channel catfish and (or) grass carp

Twelve pelicans (Pelecanus erythrorhynchos) captured in northeast Mississippi were used to determine nutrient metabolism when consuming channel catfish (Ictalurus punctatus) and(or) grass carp (Ctenopharyngodon idella). Another objective was to determine the dietary preference of pelicans when allowed to consume catfish and carp. For the 7-day metabolism trial pelicans were allotted to one of three treatment diets (4 birds/diet): catfish only,...

A retrospective study evaluating vitamin E supplementation in pelicans and plasma alpha-tocopherol concentrations in pelicans, storks, and flamingos

A retrospective study was conducted to evaluate the effectiveness of two vitamin E supplement forms in pink-backed pelicans (Pelecanus rufescens). The forms were a paste supplying 100 IU vitamin E daily or a capsule supplying 10.5 IU vitamin E daily. Baseline blood alpha-tocopherol concentrations were 7.15 ug/ml in 1998. After 10 months receiving vitamin E in the capsule form, the...

Growth rates and nutrient intake of hand-rearing pink-backed pelicans (Pelecanus rufescens) at Disney’s Animal Kingdom Lodge

Between December 18, 2006 and February 12, 2007, four pink-backed pelican (Pelecanus rufescens) chicks were hatched and hand reared at Disney’s Animal Kingdom (DAK). A pelican hand rearing protocol was developed based on that of the San Diego Zoological Society. The diet was designed to consist of combinations of capelin, smelt, sardines and herring, along with a vitamin and mineral...
