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.2007 m. rugpjūčio -2011 m. gegužės mėnesiais svarbiausiuose Oued Righ komplekso pelkynuose (Sacharos rytinė dalis, Alžyras) buvo tiriamas rudosios urvinės anties Tadorna ferruginea paplitimas ir buveinių naudojimas. Nustačius, kad šios antys peri daugumoje pelkynų komplekso vietų, rūšiai buvo suteiktas sėslios perinčios rūšies statusas, kuris skiriasi nuo ankstesnio. Didžiausias rudųjų urvinių ančių skaičius (284 individai) buvo registruojamas kiekvienų metų žiemos sezono metu (antra gruodžio mėnesio pusė). Šios rūšies antys (60% populiacijos) teikia pirmenybę vidutinio dydžio, sekliems ir druskingiems vandens telkiniams su didele atvirų plotų dalimi, pvz., Chott Tindla ir Chott Sidi Slimane ežer-ams. Buveinių naudojimo skirtumų tyrimo metais nebuvo pastebėta. Seklių druskingų vandens telkinių sezoniniai naudojimo pokyčiai gali būti dėl karšto ir sauso šio regiono klimato.

This pioneering work is the first to document the aquatic avifauna community of the Wadi Djedi in the Ziban region in southeast of Algeria. We present results obtained through the monthly counts of waterbirds conducted from September 2013 to September 2016. On this wetland we recorded 36 species of water birds representing 11 families. The Anatidae family was the most numerous, with 11 species. From among all the species, 18 were wintering species, nine were visitors, eight were sedentary breeding species (including the ruddy shelduck Tadorna furruginea and Kentish plover Charadrius alexandrines) and one species was migratory nesting (the white stork Ciconia ciconia). Two species (the teal marbled Marmaronetta angustirostris and ferruginous duck Aythya nyroca) are listed as Vulnerable on the IUCN Red List of endangered species.

The breeding ecology of the Black Kite Milvus migrans migrans in Algeria was first studied in 2014 and 2015 on Tarf Mountain in the semi-arid High Plateaus region. The nearest-neighbour nest distance was found to range from 130 to 550 m for colonial pairs and from 1,730 to 2,390 m for the solitary ones. All 12 monitored nests were placed on cliffs at different heights ranging from 149 to 155 m. The mean egg laying period was 15 days, and the mean clutch size was 2.83 ± 0.31 and 3 ± 00 eggs per nest in 2014 and 2015, respectively. The mean hatching success was 83% and that of fledging 75%. Only 2 nests were predated. Our results disagree with those of the previous studies that were carried out mainly in the Mediterranean basin and Asia, differing in such nest characteristics as the nearest - neighbour nest distance, cliff and nesting heights, egg laying period and hatching success. Otherwise, no consistent differences in clutch size and fledging success were revealed. Finally, we determined that Black Kites tend to build their nest on the eastern side of cliffs. However, our analysis showed no effect of nest placement on breeding parameters and success.
