The breeding pairs of the Algerian Nuthatch have been censused in the Guerrouch forest (Taza National Park, Jijel, Algeria). A decrease in numbers was assessed when comparing with data collected in the early 1990s. The main reason is the habitat degradation by human activities. First data were obtained by studying a nest located in a Zeen Oak. The clutch size was of 6 eggs. Incubation time was estimated to last 17 days and the nestling period likely to last 21 days. The breeding season stretched from April to early June. No evidence of second clutch.

Our study conducted from August 2007 to May 2011 in the main wetlands of the Oued Righ complex (Eastern Sahara of Algeria) aimed to study the habitat use and distribution pattern of the Ruddy Shelduck Tadorna ferruginea. As the species was recorded breeding at most sites of the wetland complex, it was given the resident breeder status, which differs from the one it had previously. The maximum number of Ruddy Shelducks (284 individuals) was recorded each year during the winter season (second half of December). The Ruddy Shelduck (60% of population) shows preference for shallow middle-sized salt ponds with a high proportion of open water (e.g. Chott Tindla and Chott Sidi Slimane). No interannual variations were observed in habitat use; moreover, seasonal variations in the use of shallow salt pond habitat may be the outcome of hot and dry climate of this arid region.
