Breeding ecology of the Cattle Egret (Bubulcus ibis) in Guerbes-Sanhadja wetlands of Algeria

Three-dimensional niche partitioning between two colonially nesting ardeid species in central China

“…Although Cattle Egrets in our study area arrived and began nesting later than Little Egrets, our results showed that Cattle Egret nests were located higher in trees by a small but statistically significant amount. There are theoretical reasons to suppose that higher nest positions should be preferred, such as unobstructed flight paths and nest hygiene (e.g., McCrimmon 1978;Parejo et al 1999;Metallaoui et al 2020). Therefore it is interesting that Little Egrets as first nesters seem not to choose the theoretically best positions.…”

“…There have been numerous studies on niche partitioning between ardeid species, but most of them have only investigated the diets of various herons (e.g., Trexler et al 1994;Salazar et al 2005;Boyle et al 2012;Choi et al 2016;Ashoori et al 2017). And there were a few studies on nest site selection (Jenni 1969;McCrimmon 1978;Burger 1979;Parejo et al 1999;Metallaoui et al 2020) and temporal separation between species within heron colonies (Weber 1975;Burger 1978;Ashkenazi and Yom-Tov 1997). Despite those separate studies of diet, nest site selection and nesting phenology, we still do not have a comprehensive understanding of niche partitioning that integrates the temporal, spatial and trophic dimensions of sympatric ardeid species.…”

A comprehensive monograph on the ecology and distribution of the House bunting (Emberiza sahari) in Algeria

“…For each nest, the following breeding parameters were obtained in each breeding year (2018-2019), for each brood and for all years and broods combined (Metallaoui et al 2020): (i) the duration of incubation (from first egg laid to hatching of all eggs), (ii) the duration of brooding (from first egg laid to chick fledging), (iii) hatching success (%; calculated as the number of eggs hatched/clutch size × 100), (iv) fledgling success (%; calculated as the number of fledglings/number of hatchlings × 100), and (v) breeding success (%; calculated as the number of fledglings/clutch size × 100).…”

“…The number of broods per year is species-specific and depends on (i) extrinsic factors: ecological conditions of the region and the quality of climatic conditions during the breeding season (especially precipitation which influences food resources), quality of the nesting site, etc., and (ii) intrinsic factors: age and breeding experience of parents, fertility of the female, etc. (Reynolds et al 2019, Metallaoui et al 2020. According to Behidj-Benyounes et al (2013), the synchronization of reproduction depends on climatic conditions, which influence the abundance, quality and availability of food and thus affect breeding success and population demographics (Bendjoudi et al 2015.…”

A 143 años de la migración de la garza bueyera Bubulcus ibis (Linnaeus, 1758) desde África hacia los Andes

“…Actualmente, se encuentra ampliamente distribuida entre África, Europa, Asia, Oceanía y América y sus poblaciones son consideradas en algunos países residentes reproductivas, residentes no reproductivas, migratorias, errantes y en estado extinto (BirdLife International, 2019;Senner et al, 2020). Además, los estudios ecológicos sobre Bubulcus ibis se han incrementado en los últimos años debido a que se comporta como un buen indicador de las perturbaciones provocadas por la acción antropogénica del hombre en los diferentes ecosistemas que coloniza (Metallaoui et al, 2020).…”
