ABSTRACT Resource partitioning is crucial for the coexistence of colonial herons, as it allows multiple species to share same habitat while minimising competition. This study took advantage a natural experiment in 2006 and 2007 when Black‐crowned Night Herons were prevented from breeding at Lake Fetzara first year due presence feral cat. event provided valuable insight into spatial temporal dynamics nest site selection among coexisting heron species, which consisted Cattle Egrets ( Ardea...
Capsule This is the first study of reproductive ecology Little Bittern Ixobrychus minutus in North Africa. During period, clutch size exhibited a sharp drop concurrent with steady human encroachment and 30% habitat loss. Aim To investigate status, nest-site selection, breeding parameters, chick development diet Algeria, under deteriorating conditions Methods Data were collected during surveys all major Algerian wetlands (2002–08) monitoring at Boussedra, freshwater marsh northeast years 2005...
The status and breeding success of Glossy Ibis (Plegadis falcinellus) in Numidia, Algeria factors affecting its conservation North Africa were investigated during 2002–2007. After a century half apparent interruption, reproduction was once again noted at Lake Fetzara three new sites: Dakhla, Chatt Tonga. At the latter site, colonies shifted location annually between 2002 2006 often split into subcolonies located on distinct islets. Egg-laying occurred mid-April end June, beginning over month...
Abstract During 2002–2007, we assessed the status of Purple Heron Ardea purpurea in Numidia, Algeria by surveying all major wetlands region. We located six distinct breeding sites; four these were not previously known. also investigated nest site selection and determined species' reproductive success at Dakhla, a dunary pond during two successive years (2006 2007). The egg laying period was comparable to that reported for southern Europe (March-May) seasonal change recorded. A growth curve...
In the Mediterranean basin, Greater Flamingos Phoenicopterus roseus constitute a metapopulation with natal and breeding dispersal among colonies. However, rate of exchange between European North African colonies remains poorly known. this paper, we document wintering flamingos in Algeria provide first post-fledging data for born Algeria. At Algeria, most ringed birds (99.4% 835 birds) originated from north-western (397 individuals France, 369 Spain, 57 Sardinia seven continental Italy), but...
Between 2013 and 2016 we conducted an inventory characterization of aquatic avifauna at Lake Tonga, a Ramsar site. We identified 61 species belonging to 17 families, dominated by Anatidae with 14 species. The inventoried have different phenological status. Some are known for their regular wintering some summer concentrations, while others residents year round. Population analysis showed the presence endangered such as Oxyura leucocephala, Marmaronetta angustirostris Aythya nyroca, that...
Global changes are inducing migratory birds to advance their annual cycle. However, in the time of arrival at breeding grounds have significant fitness implications. This study aims identify factors affecting variability white storks ( Ciconia ciconia L.) and determine if North African is occurring earlier. We monitored ringed a colony Algeria between 2017 2021. The arrived this over an extended period spanning mid-December mid-June each year. found that stork was negatively correlated with...
How environmental changes are affecting bird population dynamics is one of the most challenging conservation issues. Dietary studies top avian predators could offer scope to monitor anthropogenic drivers ecosystem changes. We investigated diet breeding Eleonora's falcon in an area Northeastern Algeria years 2010-2012. Feathers and insect remains originating from prey plucking behavior were analyzed, providing insights into seasonally changing this raptor, as well trans-Mediterranean...
The movement of organisms is a central process in ecology and evolution, understanding the selective forces shaping spatial structure populations essential to conservation. Known as trans-Saharan migrant capable long-distance flights, Glossy Ibis Plegadis falcinellus' dispersal remains poorly known. We started ringing scheme 2008, first its kind North Africa, ringed 1121 fledglings over 10 years, which 265 (23.6%) were resighted. Circular statistics finite mixture models natal indicated: (1)...
The diversity and spatial distribution of ectoparasites a large colony white stork Ciconia ciconia at Dréan, in north-eastern Algeria, were investigated during two consecutive breeding seasons. results indicated that nestlings infested by the following four louse species: Colpocephalum zebra (Burmeister, 1838), Neophilopterus incompletus (Denny, 1842), Ardeicola ciconiae (Linnaeus, 1758), Ciconiphilus quadripustulatus 1838). Overall, chewing lice exhibited clustered distribution, with C....
The breeding distribution of the Gull-billed Tern Gelochelidon nilotica in Algeria is poorly known as species mainly associated with highly unstable habitats. We conducted a survey across all major Algerian wetlands and monitored colony at El Goléa during 2009. usually described passage migrant Sahara, but its status may have to be reconsidered following our discovery small nesting on an islet Sebkhet Maleh, Goléa. consisted 25 birds which built nine nests foraged exclusively around salt...

Abstract. We used a large dataset of greater flamingo chicks banded and measured at Camargue, France, to verify the applicability discriminant function analysis sex this species. Males females sexed genetically differed significantly in all morphological characters (body mass, tarsus wing length), with males being larger than females. Although rate varied substantially from one year another, we found that it increased sample size individuals. Our results suggest (DFA) does not provide an...
During the period 2002–2012, we assessed breeding status of Grey Heron Ardea cinerea in Algeria by surveying all major wetlands region. We located two distinct sites; one them was recorded for first time. also investigated nest site selection, measured parameters and derived a growth curve developing chicks. Although wintering Herons increased numbers region, number pairs did not change markedly over past century. The reasons scarcity rest North Africa are discussed.
The Maghreb population of Emys orbicularis extends over a narrow strip northern Morocco, Algeria, and Tunisia. Our understanding the presence this turtle in contrast to Morocco Tunisia, is quite limited frequently rests on few small-scale studies or even reports from century ago. present study provides first complete data distribution level threat species Algeria. A field survey was carried out based obtained scattered local available that suggested Algerian wetlands. Data climatic habitat...
Recognizing, assessing, and responding to threats is critical for survival in the wild. Birds, especially their role as parents, must decide whether flee or delay flight when threatened. This study examines how age, reproductive stage, presence of a mate influence initiation distance (FID) nest recess duration white storks. Analyzing data with generalized additive mixed model (GAMM), we found significant correlations between FID mate. These results suggest that trade-off current future...
