Abstract:

The ecology (phenology and diurnal eco-ethology) of the ferruginous duck Aythya nyroca was studied during three seasons of its wintering (2010/2011, 2011/2012, and 2012/2013) in Garaet Hadj Tahar (a Ramsar site since 2001 with an area of 120 ha, complex of Guerbes-Sanhadja, Skikda, Northeast of Algeria).
