Phenology and diurnal behavior of Northern Shoveler (Anas clypeata) and Eurasian Teal (Anas crecca crecca) at marsh of El-Feid (Northeast of Algeria)

Abstract

An ecological study of the Northern Shoveler (Anas clypeata) and Eurasian Teal (Anas crecca crecca) in the marsh of El-Feid was performed during two wintering season (2014/15 and 2015/16) which showed that these two species were regularly wintering in this ecosystem. The highest numbers were recorded during November 2014, when Eurasian Teal reach 637 individuals and Northern Shoveler reach 485individuals. The population of these two Anatidae was highest during the first wintering season than the second. Sleeping activity (or diurnal resting) dominate the diurnal behaviors of these two Anatidae at marsh of El-Feid and represent 38% for the Northern Shoveler and 41% for the Eurasian Teal.
