Distribution and abundance of resident and migratory seabirds in the Commune Estuary Real Province of Santa Elena

Abstract

The estuary of the El Real Commune in the Province of Santa Elena - Ecuador, is used as a resting and feeding site for several species of seabirds. The study allowed to know the distribution and abundance of resident and migratory seabirds through 35 monitoring during the months of November, December, 2014 and January, 2015. There were 12 species of birds with a total of 62020 ind., Fregata magnificens; 816 ind., Himantopus mexicanus; 182 ind., Anas bahamensis; 119 ind., Nictanassa violacea; 66 ind., Egretta thula; 57 ind., Actitis maculariu; 29 ind., Pelecanus occidentalis; 20 ind., Ardea alba; 15 ind., Platalea ajaja; 14 ind., Pelecanus thagus; 6 ind., Jacana jacana; 1 ind., Eudocimus albus. The Simpson, Shannon Wiener and Pielou Indexes for November 0.0344; 0.11; 0.0458, December 0.04195; 0.132; 0.0573 and January 0.04711; 0.1444; 0.0581, showed that the study site is a habitat that is not diverse in variety of species but abundant for a single species of the Fregatidae family whose groupings were georeferenced along the shores of the El Real estuary.
